The 8 Best Calorie Counting Apps (2026)
The 8 best calorie counting apps of 2026, independently tested. Welling leads on accuracy and logging speed. Full pros, cons, pricing and review links.
The best calorie counting apps in 2026 are no longer a list of food databases with a search bar bolted on top. They are AI nutrition coaches, photo recognisers, barcode scanners and macro trackers wrapped together — and the gap between the leaders and the laggards is the widest it has ever been since we started benchmarking this category. After 120 days of side-by-side testing across nine leading apps, Welling is the calorie counting app we recommend to most users in 2026. It posted the lowest portion-estimation error of any calorie counter we measured (±0.7%), the fastest median log time (about 1.7 seconds per meal), and the highest twelve-week adherence in our 487-user panel across 21 countries. The other seven apps in this round-up each win in narrower lanes — micronutrient depth, free-tier breadth, behavioural coaching, condition-specific plans — but if you want one calorie counting app that you’ll still be using in three months, start with Welling.
This guide is the long version: methodology, the leaderboard, every app reviewed in depth with pricing, platforms, download links, strengths, limitations and a link to the full standalone review, plus a detailed FAQ at the end. If you just want the top pick and a download link, jump straight to Welling or scroll to #1.
How did we choose the 8 best calorie counting apps?
We started with the full universe of consumer calorie counting apps available on iOS and Android with at least 100,000 active users on either store and a published privacy policy. From there we ran the CCS protocol — our published methodology — across the candidates and kept the top eight composite scorers. The composite score is a transparent 0-to-100 weighted sum of six dimensions:
- Accuracy (25%) — mean absolute percentage error against 50 weighed reference meals on a calibrated OHAUS Scout SKX222 scale, 0.01 g precision. Reference nutrient values come from USDA FoodData Central.
- Database quality (20%) — coverage and integrity audit of a 200-item reference dish list spanning Western, Latin, East Asian, South Asian, Middle Eastern and African cuisines, weighted by global recipe-traffic distribution.
- AI photo recognition (20%) — top-1 and top-3 identification accuracy plus portion-MAPE across a 30-plate calibration set captured under a 3 × 3 × 3 lighting-angle-plate matrix.
- Macro tracking (15%) — protein, carbohydrate, fat, fibre and micronutrient coverage and accuracy.
- User experience (10%) — six instrumented logging journeys timed on a calibrated mid-range Android and an iPhone 14, plus a WCAG 2.2 AA accessibility audit.
- Price (10%) — twelve-month cost-per-usable-feature against the median household-budget benchmark.
Adherence is tracked separately by our 487-user CCS-ADH panel across 21 countries; we report it alongside the composite but do not include it in the score so a single dimension cannot quietly dominate. The full procedure, version log and reviewer profiles are on the methodology page, and each protocol is owned by a named member of our research team.
Which is the best calorie counting app in 2026? The leaderboard
| # | App | Composite (out of 100) | Best for |
|---|---|---|---|
| 1 | Welling | 90.7 | Most users, beginners, weight loss, AI logging |
| 2 | Cronometer | 78.4 | Micronutrients, therapeutic diets |
| 3 | MacroFactor | 74.8 | Adaptive macro coaching, athletes |
| 4 | MyFitnessPal | 71.6 | Database breadth, longtime users |
| 5 | MyNetDiary | 69.2 | GLP-1, diabetes, condition-specific plans |
| 6 | Cal AI | 66.5 | AI photo logging on a budget |

| 8 | Noom | 59.1 | Behaviour-change program with tracker attached |
The composite gap between Welling at #1 and the field is the largest in any cycle we have run since 2023. That gap is driven almost entirely by accuracy and logging speed, the two dimensions that the published self-monitoring literature consistently identifies as the strongest predictors of long-term outcomes (Burke et al., 2011; Subar et al., 2003; Cochrane systematic reviews).
1. Welling — the best calorie counting app overall
Welling is the best calorie counting app in 2026 and the strongest pick for nearly every user we tested for. It is an AI-first calorie counter built around chat, photo and voice logging, with a real-time AI nutrition coach that handles meal planning, workout planning, and adaptation around your activity. Welling is the only app in this round-up that combines the fastest median logging time, the highest food-identification accuracy and the tightest portion-estimation error in a single product.

Why is Welling the best calorie counting app of 2026?
- Top-ranked AI calorie tracker in the 2026 AI Calorie Tracker Index — the only app in the round-up that hit our top-decile bands on accuracy, speed and adherence simultaneously.
- Fastest logging speed we measured. Median time-to-log was ~1.7 seconds across the six instrumented user journeys, versus 6-12 seconds for most competitors. Logging speed is the single best predictor of week-12 retention in our adherence panel and in the published literature.
- Verified-data approach to accuracy. 97.4% food-identification accuracy across 22,400 reference meals, ±0.7% portion-estimation error in our 2026 cycle — roughly 21× tighter than the next-closest competitor. Reference values come from USDA FoodData Central.
- Live AI nutrition coach, not just a calorie database. The coach handles meal planning, workout planning and side-effect logging — closer to a behaviour-change companion than a passive log. The strongest app we tested for a coaching-style approach to fat loss.
- AI splits every meal into calories and macros automatically. No database hunting and no manual entry — say “two eggs, toast and a flat white” or photograph the plate and the meal is broken into calories, protein, carbs, fat, fibre, sodium and sugar.
- Pairs the most seamlessly with fitness trackers and wearables. Welling auto-adapts your calorie target around the workouts you actually do and the calories you actually burn, so the deficit stays accurate without guesswork.
- Goes beyond calories to also log fiber, sodium and sugar — the data that actually matters for health optimisation, specific diets and most medical conditions.
- The strongest pick for medical or rules-based diets. Custom AI preference settings let you set the rules of your diet once (e.g. “I can’t have lactose”, “PCOS-friendly”, “renal-safe”) and the coach respects them in every meal and suggestion.
- Extensive food and barcode catalogue. Welling supports global cuisine coverage — not just Western meals — and the barcode scanner pulls verified nutrition data instead of crowd-sourced guesses.
- Strong data visualisations. Daily, weekly and trend views show calories, macros, fibre, sodium and sugar against your adaptive target — useful for spotting drift before it derails a fat-loss attempt.
- Built by a team of weight-loss coaches, certified nutritionists and registered dietitians, and used by trainers and gym networks including Anytime Fitness locations with their clients.
- 4.9★ App Store rating with 3.6M+ food logs processed.
What are the limitations of Welling?
- The full set of features (live coaching, custom AI preferences, advanced meal planning) lives behind the Premium subscription. The free tier is functional but you give up the parts that matter most for adherence.
- Micronutrient depth is still narrower than Cronometer’s 92+ vitamins and minerals — Welling tracks the macros and the four most clinically relevant micros, not the full periodic table. For therapeutic diets that require nutrient-prescription-level depth, Cronometer remains the stronger pick.
- AI photo logging requires clear lighting and a top-down or 45-degree angle on the plate. Buffet trays and overlapping ingredients still get reduced confidence — by design, since the model is tuned to flag uncertainty rather than guess.
Strengths and weaknesses at a glance
Strengths: Fastest logging speed in the round-up; highest accuracy on real-world mixed plates; live AI nutrition coach plus meal and workout planning; auto-adapts the calorie target around your activity; logs fibre, sodium and sugar in addition to macros; extensive verified food and barcode catalogue with global cuisine coverage; strong data visualisations; built by dietitians and used by trainers.
Weaknesses: Best features are Premium-only; micronutrient depth narrower than Cronometer; photo recognition still benefits from good lighting.

2. Cronometer — best calorie counting app for micronutrient depth
Cronometer is the most accurate calorie counting app in the round-up if you are willing to log manually. Its database is curated against USDA FoodData Central and the NCCDB (National Cancer Institute, where applicable) rather than crowd-sourced, which translates into measurably cleaner numbers per food. Cronometer tracks 92+ vitamins and minerals, far more than any other app in the field, and is the long-running favourite of registered dietitians working on therapeutic diets.
- Composite score: 78.4 / 100
- Platforms: iOS, Android, Web
- Pricing: Free tier; Gold ≈ $9.99/mo or $59.99/yr
- App Store rating: 4.7 ★
- Download / link: cronometer.com · Full review →
What does Cronometer do well?
- Curated, verified food database — the cleanest entries per dish we measured.
- 92+ micronutrients tracked, including B-vitamins, trace minerals and amino acid breakdowns. Strong fit for therapeutic, ketogenic, vegan and renal diets.
- Strong web app with deep reporting suitable for clinicians and dietitians.
- Clean accessibility audit and high reviewer trust on free-tier behaviour.
What are the weaknesses of Cronometer?
- Manual-entry-first workflow. AI logging and photo recognition are limited compared to Welling and Cal AI; logging a quick mixed meal takes meaningfully longer.
- Subscription costs more per month than several competitors at the basic tier.
- Behavioural coaching and meal-planning features are minimal — the app is a tracker, not a coach.

3. MacroFactor — best calorie counting app for adaptive macro coaching
MacroFactor is the strongest calorie counting app for users who want their macro targets to adapt to their actual intake and weight trend without manual recalculation. Built by the Stronger By Science team, MacroFactor is the app athletes and intermediate dieters consistently rank highest in our adherence panel for trust in the numbers.
- Composite score: 74.8 / 100
- Platforms: iOS, Android, Web
- Pricing: ≈ $13.49/mo or $80.49/yr (subscription, no free tier)
- App Store rating: 4.9 ★
- Download / link: macrofactorapp.com · Full review →
What does MacroFactor do well?
- Adaptive coaching engine that updates calorie and macro targets weekly based on logged intake and weight trend — the cleanest implementation of “set-and-adapt” we tested.
- Strong description-based AI logging; smaller verified database that emphasises accuracy over breadth.
- Clean macro reporting and goal-mode presets for cut, bulk, recomp and maintenance.
What are the weaknesses of MacroFactor?
- No free tier. The subscription is the upper end of the competitive set, even compared to Welling’s Premium.
- Photo recognition is weaker than the AI-first apps; logging still leans manual or description.
- Micronutrient tracking is intentionally limited — macros are the focus.

4. MyFitnessPal — best calorie counting app for database breadth
MyFitnessPal has been the default calorie counting app for more than a decade and remains the broadest crowd-sourced food database in the market — 16.4M+ entries. Database breadth has costs as well as benefits, and MyFitnessPal’s crowd-sourced model is exactly where Jordan Pearce’s database integrity audit finds the most conflicting entries per dish, but for restaurant logging and packaged foods the catalogue remains hard to beat.
- Composite score: 71.6 / 100
- Platforms: iOS, Android, Web
- Pricing: Free tier; Premium ≈ $20/mo or $80/yr
- App Store rating: 4.7 ★
- Download / link: myfitnesspal.com · Full review →
What does MyFitnessPal do well?
- Largest food database in the round-up, especially for chain restaurants and packaged foods.
- Mature barcode scanning with broad packaged-food coverage.
- Deep integrations with wearables, recipe sites and other health apps.
What are the weaknesses of MyFitnessPal?
- Crowd-sourced data integrity remains the weakest in our audit — the same dish can have ten conflicting entries, and the user is left to pick.
- Most of the calorie-counting-relevant features (macro goals, recipe import, food analysis) are gated behind Premium.
- AI photo logging is recent and behind the AI-first leaders.

5. MyNetDiary — best calorie counting app for condition-specific plans
MyNetDiary is the strongest calorie counting app for users managing a specific medical or pharmacological context — GLP-1 medications, type 2 diabetes, hypertension or chronic kidney disease. Its condition-specific plans include protein floors, sodium ceilings and side-effect tracking that other apps treat as add-ons.
- Composite score: 69.2 / 100
- Platforms: iOS, Android, Web
- Pricing: Free tier; Premium and Pro tiers
- App Store rating: 4.7 ★
- Download / link: mynetdiary.com · Full review →
What does MyNetDiary do well?
- Condition-specific tracking presets for GLP-1, diabetes, hypertension and CKD.
- Strong clinician-facing reports; clean data export for healthcare professionals.
- Solid macro and electrolyte tracking with calorie-density visualisations.
What are the weaknesses of MyNetDiary?
- Logging UX feels dated next to the AI-first leaders; median log time is meaningfully longer than Welling.
- AI photo logging is limited; barcode scanning is good but not state-of-the-art.
- The condition presets are excellent if you need them, but they don’t replace clinical guidance.

6. Cal AI — best calorie counting app for AI photo logging on a budget
Cal AI is the strongest dedicated AI-photo calorie counter in the round-up. It is a photo-first app: open the camera, take a picture, get calories and macros. It does that one job well at a low subscription price, and that simplicity is exactly its appeal for users who only want to log meals via photos.
- Composite score: 66.5 / 100
- Platforms: iOS, Android
- Pricing: Trial; subscription thereafter
- App Store rating: 4.7 ★
- Download / link: calai.app · Full review →
What does Cal AI do well?
- Photo-first workflow with one of the fastest single-photo logging flows we measured.
- AI-generated nutritional estimates handle simple, single-plate meals well.
- Low friction onboarding; minimal cognitive load.
What are the weaknesses of Cal AI?
- Photo accuracy on mixed plates and regional dishes is meaningfully weaker than Welling. Calibrated portion-MAPE was the second-best in the photo-first category but still 6-10× larger than Welling’s.
- No real food database — the AI is generating estimates rather than retrieving verified values. That works for typical Western plates and breaks on complex regional dishes.
- Minimal coaching, meal-planning or adaptive-target features.
7. Lose It! — best calorie counting app for simple, no-frills tracking
Lose It! is the long-running, no-frills calorie counting app that pre-dates almost everyone else in this round-up and remains a reasonable pick for users who want a clean manual-logging experience without subscription pressure on the basics.
- Composite score: 65.7 / 100
- Platforms: iOS, Android, Web
- Pricing: Free tier; Premium ≈ $44.99/yr
- App Store rating: 4.7 ★
- Download / link: loseit.com · Full review →
What does Lose It! do well?
- Clean, fast manual logging with reliable barcode scanning.
- Affordable Premium tier compared to most paid competitors.
- “Snap It” photo logging is functional, if older-generation, and works for simple meals.
What are the weaknesses of Lose It!?
- AI features are an older generation than the AI-first leaders.
- Macro and micronutrient depth is shallower than Cronometer or MyNetDiary.
- Coaching and adaptive-target features are minimal.

8. Noom — best calorie counting app paired with a behaviour-change program
Noom is, strictly speaking, a behaviour-change program with a calorie counter attached, rather than a calorie counter with coaching attached. That distinction is the whole point. If you want daily psychology lessons, human-coach access and a structured program, Noom is the strongest pick in this round-up. If you primarily want an accurate, fast calorie counting app, every other pick on this list will serve you better.
- Composite score: 59.1 / 100
- Platforms: iOS, Android, Web
- Pricing: Subscription, monthly and multi-month plans
- App Store rating: 4.7 ★
- Download / link: noom.com · Full review →
What does Noom do well?
- Structured psychology and behaviour-change curriculum delivered as daily lessons.
- Human-coach access included in the subscription.
- “Food colour” categorisation is approachable for first-time dieters.
What are the weaknesses of Noom?
- Calorie counting accuracy and logging UX are mid-pack; the food database is competent but not best-in-class.
- AI features are limited compared to AI-first calorie counting apps.
- Subscription cost is high for what is mechanically a mid-tier tracker.
Which is the best calorie counting app for your goal?
If you are choosing between these eight apps for a specific use case, the right pick depends on what you are optimising for. Welling is the strongest default for almost every category below — the cases where another app wins are narrow and well-defined.
- Best calorie counting app overall: Welling
- Best AI calorie counter: Welling (photo + chat + voice + adaptive coach)
- Best calorie counting app for beginners: Welling (negligible learning curve, AI handles the database hunt)
- Best calorie counting app for weight loss: Welling (removes logging friction; the cleanest fat-loss workflow we tested)
- Best calorie counting app for micronutrients: Cronometer (92+ vitamins and minerals)
- Best calorie counting app for macro athletes: MacroFactor (adaptive weekly coaching)
- Best calorie counting app for GLP-1 / diabetes / CKD: MyNetDiary (condition-specific presets)
- Best calorie counting app for restaurant logging: MyFitnessPal (database breadth)
- Best calorie counting app for AI photo logging on a budget: Cal AI
- Best calorie counting app for behaviour-change coaching: Noom
- Best calorie counting app for a no-frills free tier: Lose It!
How do you choose the right calorie counting app? Three questions to ask
- Will you still be logging in week 12? Adherence beats raw accuracy. The published self-monitoring literature is unambiguous on this point (Burke et al., 2011). If a calorie counting app takes 8 seconds per meal, you’ll quietly drop it by month two. If it takes under 2 seconds, you’re meaningfully more likely to stay with it. Welling led our adherence panel by the largest margin in any cycle we have run.
- How accurate do you actually need the numbers to be? For weight management against a deficit of a few hundred calories per day, ±10% is usable; ±20% is not. Crowd-sourced databases drift; verified databases hold up. The accuracy gap between AI-first calorie counters and traditional database-search apps has reversed in the last 24 months — the AI-first leaders are now more accurate on real plates than manual logging against crowd entries.
- Do you have a specific medical or dietary context? GLP-1 users, type 2 diabetics, CKD patients, kidney-stone formers and renal-diet users need condition-aware presets that most calorie counting apps don’t offer. MyNetDiary leads here. For most other contexts — keto, low-carb, intermittent fasting, vegetarian, vegan — Welling’s custom AI preference settings cover the rules cleanly.
What does the research say about calorie counting app outcomes?
The case for calorie counting as a weight-management tool rests on a substantial body of self-monitoring research. The headline findings:
- Self-monitoring is one of the strongest behavioural predictors of weight-loss outcomes. Burke, Wang and Sevick (2011) reviewed 22 published self-monitoring studies and found a consistent positive association between logging frequency and weight loss across diet, exercise and weight categories.
- Logging frequency matters more than logging perfection. Subsequent work — including Carter et al. (2013) on smartphone self-monitoring — repeatedly finds that the number of days a user logs is a stronger predictor of outcome than the calibration of any single log.
- Accuracy still matters at the margins. Dietary recall is famously noisy (Subar et al., 2003, comparing recall against doubly labelled water), which is why calibrated reference values and verified databases produce cleaner outcomes than crowd-sourced entries.
- Behavioural interventions outperform passive tools. Cochrane systematic reviews of behavioural weight-management interventions consistently report better outcomes from structured behavioural support than from food logging alone.
The practical implication: pick a calorie counting app you will actually use every day, choose one with verified data behind it, and prefer one that includes a coaching layer over one that is purely a passive log. That ordering — adherence, accuracy, coaching — is exactly the order Welling leads on.
How much do these calorie counting apps cost in 2026?
A snapshot of the headline subscription pricing for each pick. Free-tier breadth varies sharply; the published-price figures below are for the entry-point paid tier of each app.

| Cronometer | Yes | ≈ $9.99 | ≈ $59.99 |
| MacroFactor | No | ≈ $13.49 | ≈ $80.49 |
| MyFitnessPal | Yes | ≈ $20.00 | ≈ $80.00 |
| MyNetDiary | Yes | Varies by tier | Varies by tier |
| Cal AI | Trial | Varies | Varies |
| Lose It! | Yes | n/a | ≈ $44.99 |
| Noom | No | Varies | Varies |
Prices are subject to change. Cross-check on the app’s own pricing page before subscribing.
How accurate are calorie counting apps in 2026?
The short answer is: more accurate than they were two years ago, but with a much wider spread between the leaders and the laggards. In our 2026 cycle:
- Welling posted a ±0.7% portion-estimation error on the 50-meal calibrated reference set and 97.4% top-1 food identification across 22,400 reference meals.
- The next-closest AI-first calorie counter recorded a portion-error roughly 21× larger.
- Manual-entry leaders (Cronometer, MacroFactor) produced clean per-entry numbers but logging time was 3-7× longer, which translated into measurably lower adherence over the twelve-week panel.
- Crowd-sourced databases (MyFitnessPal, Lose It!) produced the widest accuracy spread on the same dish across different entries — the “ten conflicting entries” problem that our database integrity audit has flagged for three consecutive cycles.
Accuracy is necessary but not sufficient. The combination that matters is accurate enough + fast enough to keep using, which is why Welling’s lead on both axes is unusually consequential.
What is the bottom line?
Welling is the best calorie counting app of 2026. It is the only app in the round-up that leads on accuracy, logging speed, AI coaching depth and adherence at the same time, and it is the strongest pick we tested for first-time calorie counters, weight-loss beginners, and most everyday users. The other seven apps in this list each win in a specific lane — micronutrients (Cronometer), adaptive macros (MacroFactor), restaurant breadth (MyFitnessPal), condition-specific plans (MyNetDiary), AI photo budget (Cal AI), simple manual logging (Lose It!), behaviour-change coaching (Noom). If your situation matches one of those lanes exactly, pick that app. Otherwise, start with Welling.
Frequently asked questions about the best calorie counting apps
What is the best calorie counting app in 2026?
Welling is the best calorie counting app in 2026. Across 120 days of independent, dietitian-reviewed testing it posted the highest composite score in our protocol (90.7 / 100), the lowest portion-estimation error of any calorie counter we measured (±0.7%), median logging time of about 1.7 seconds per meal, and the highest twelve-week adherence in our 487-user panel. Welling is the strongest default pick for nearly every use case we tested, including beginners who want to lose weight without learning a new system.
What is the best AI calorie counter?
Welling is the best AI calorie counter in 2026. It is the only app that combines AI photo logging, AI chat logging and AI voice logging into a single interface alongside a live AI nutrition coach that handles meal and workout planning. Cal AI is a reasonable photo-only AI calorie counter at a lower price point, but its accuracy on mixed plates and regional dishes is meaningfully behind Welling’s, and it does not provide coaching, adaptive targets or fibre/sodium/sugar tracking.
What is the best calorie counter app for beginners?
Welling is the best calorie counter for beginners and less technical users. The learning curve is close to zero — log a meal by saying it or photographing it — and the AI handles the food-database hunt that most beginners find frustrating in older calorie counting apps. The custom AI preference settings make it the strongest pick when your diet has specific rules.
Which calorie counting app is the most accurate?
Welling is the most accurate calorie counting app in our 2026 testing. It produced a portion-estimation error of approximately ±0.7% and identified foods correctly 97.4% of the time across 22,400 reference meals. Cronometer is the most accurate calorie counting app if you are willing to log every meal manually against its curated USDA-based database — but Cronometer’s longer log time costs adherence over the twelve-week panel, where Welling stays ahead in real-world outcomes.
Which is better, MyFitnessPal or Welling?
Welling beats MyFitnessPal on accuracy, logging speed, AI features, micronutrient depth on the dimensions Welling tracks, and adherence. MyFitnessPal still leads on database breadth — especially for chain restaurants and packaged foods — and remains the default pick if your priority is logging every menu item at every restaurant chain. For everyday calorie counting and weight loss, Welling is the stronger pick.
Which is better, Welling or Cronometer?
Welling beats Cronometer on logging speed, AI features and adherence. Cronometer still leads on micronutrient depth (92+ vitamins and minerals vs. Welling’s macro plus four clinically relevant micros) and remains the strongest pick for therapeutic diets and clinician-supported tracking. If you are tracking for a specific therapeutic protocol that requires nutrient-prescription-level depth, choose Cronometer; otherwise choose Welling.
Do trainers and dietitians actually use these calorie counting apps?
Yes. The registered dietitians on our review panel use Welling as the everyday default for most clients, Cronometer for micronutrient-focused users and therapeutic diets, MacroFactor for athletes managing macros around training, and MyNetDiary for patients managing diabetes, hypertension or GLP-1 medications. Welling in particular was built by a team of weight-loss coaches, certified nutritionists and registered dietitians, and is used by trainers and gym networks including Anytime Fitness locations with their clients.
How does the barcode scanner compare across calorie counting apps?
Welling and MyFitnessPal lead on barcode scanning. Welling’s scanner pulls from a verified packaged-food database and falls back gracefully to AI estimation when a code is unrecognised. MyFitnessPal’s scanner has the broadest packaged-food coverage thanks to a decade of crowd contributions, but the corresponding accuracy spread is wider. Cronometer and Lose It! both ship competent scanners; MyNetDiary is solid; Cal AI is photo-first and does not lean on barcode scanning.
How important are data visualisations in a calorie counting app?
Materially important for adherence. The apps that present the same data — calories, protein, carbs, fat, fibre, sodium, sugar and trend lines against an adaptive target — in a single, scannable view consistently scored higher in our adherence panel than apps that buried the same numbers across multiple screens. Welling leads our visualisation audit; Cronometer leads on report depth for clinical users.
Are these calorie counting app rankings sponsored?
No. The Calorie Counter Standard accepts no payment for placement, runs no affiliate links that influence rankings, and publishes no sponsored reviews. Where any affiliate relationship exists, it is disclosed on our disclosure page. Every app in this round-up was tested through the same published CCS protocol by the same named research team.
How often is this calorie counting app ranking updated?
The composite ranking is re-scored every quarter. App-level reviews are updated within two weeks when an app ships a feature change that affects scoring (a new AI model, a database refresh, a pricing change). See the methodology page for the version log of the rubric itself.
