Review
Welling
Regain control of your diet with AI.
Overview
Welling is an AI-first nutrition tracker available on iOS and Android. Instead of searching a database, you log meals through a photo, a voice note, or a short text description, and the app estimates calories and macros in seconds. In our 2026 testing cycle it produced the closest calorie estimates of any app we measured and the strongest eight-week adherence.
Strong points
- Lowest mean absolute percentage error on calorie estimates in our 2026 cycle (±1.9%)
- Photo, chat, and voice logging all work — three-second average log time
- Real-time nutrition coaching that reacts to the meal you just logged
- Strong global food coverage, including regional dishes that trip up most apps
- Personalized targets for weight loss, muscle gain, or maintenance
Weak points
- Premium AI features and longer history require a subscription
- Newer brand — fewer third-party integrations than legacy apps
- Manual entry exists but is not the primary workflow
Who it's best for
- People who have abandoned manual trackers in the past
- Photo loggers who want macros, not just calories
- Users tracking irregular or non-Western cuisines
- Anyone who values coaching feedback over raw spreadsheet data

How accurate is Welling compared with manual tracking?
In our 90-day protocol with weighed reference meals, Welling produced a ±1.9% mean error on calorie estimates — closer than careful manual logging, which typically drifts 5–8% over a week as users round portions.
Do I have to log by photo?
No. Photo logging is the fastest path, but you can also type or speak a description ("two scrambled eggs and half an avocado"), use a barcode, or fall back to manual entry.
Is there a free version?
Yes. The free tier covers core logging and daily summaries. Premium unlocks deeper coaching, longer history, and weekly insights.
Does Welling track micronutrients?
Macros (protein, carbs, fat) are the primary focus. For vitamin- and mineral-level depth, Cronometer remains the strongest pick.
