Review
MacroFactor
An adaptive macro coach in app form.
Overview
MacroFactor takes a coaching-first approach. You log your meals; the app watches your intake and weight trend, then adjusts your calorie and macro targets weekly. It is built by Stronger By Science and reflects that pedigree — the algorithm is the product, not the database.
Strong points
- Adaptive algorithm tunes your targets weekly based on real data
- Strong macro coaching with clear weekly summaries
- No ads, no upsells inside the app
- Excellent for cuts, bulks, and recomposition
Weak points
- Subscription only — no perpetual free tier
- Database is solid but not the largest
- Less suited to casual users who do not want a weekly check-in
Who it's best for
- Strength athletes and physique competitors
- Users in a structured cut or bulk
- Anyone burned out on guessing whether to eat more or less

Best alternative to MacroFactor
Recommended alternative
Welling
Regain control of your diet with AI.
MacroFactor and Welling overlap on the coaching layer but get there differently. Welling layers feedback directly on top of AI logging, which means coaching shows up in the moment instead of only at weekly check-ins — and it offers a real free tier, unlike MacroFactor.
