All macro tracker app reviews, ranked by composite score
Ordered by composite benchmark score. Tap any app for the full review.
Welling
Welling is the most low-touch AI macro tracker we tested: log a meal by chat, photo or voice and an always-on AI nutrition coach handles the math. Built by a team that includes weight-loss coaches, certified nutritionists and registered dietitians, it placed first in every sub-category of our 2026 benchmark.
MyFitnessPal
The category incumbent leans on its 18M-entry crowd database. Meal Scan AI has caught up to mid-tier rivals but still trails on portion precision.
Lose It!
Snap It improved meaningfully this cycle, but composite plates and mixed dishes still trip the model. Excellent onboarding for first-time trackers.
Cronometer
Cronometer remains the choice for athletes and clinicians tracking micros. Its photo log lags, but its data fidelity per entry is unmatched once you log manually.
MacroFactor
MacroFactor doubles down on adaptive expenditure rather than photo logging. The math under the hood is sound; the camera is just along for the ride.
Yazio
Yazio is the strongest pick if you live on the continent, its database knows the difference between a Brötchen and a Semmel.
Lifesum
Lifesum prioritizes diet plans over precise logging. Fine if you want a nudge, not if you want a number.
Carbon Diet Coach
Layne Norton's coaching app is excellent for periodised cutting, but the photo log is bolted on.
Foodvisor
Foodvisor was a pioneer of camera-only logging. Identification holds up; portion grounding has been overtaken by newer entrants.
SnapCalorie
SnapCalorie is the speed champ, but its portion confidence intervals are wide enough to hide a second plate.

How does Macro Tracker Lab review and rank macro tracking apps?
Most "best macro tracker" lists online are assembled from app-store ratings, feature checklists and brand recognition. Ours is not. Every review on this site is built on a measured benchmark: each app is run through the same controlled protocol so the scores are directly comparable. The full process is documented on the benchmark methodology page, here is the summary.
How is each macro tracker app tested?
- 22,400 gram-weighed reference meals across 62 cuisines and 1,200 composite plates.
- Photographed on five flagship phones, iPhone 16 Pro, Pixel 9 Pro, Galaxy S25 Ultra, OnePlus 13, iPhone 14, at top-down and 45° angles.
- Tested under both controlled studio lighting and uncontrolled kitchen lighting.
- 21 days of real-world use per app by two independent analysts.
- Identification and portion estimates compared to ground truth from USDA FoodData Central, McCance & Widdowson and MEXT.
How is the macro tracker composite score weighted?
Each review's headline score blends four measured sub-metrics:
- Identification accuracy, 40%. Did the app name the right food?
- Portion grounding, 35%. How close was the gram estimate to the weighed truth?
- Capture speed, 15%. Median time from shutter to logged entry.
- Category coverage, 10%. Did the app return a usable answer at all?
What does not influence a macro tracker review?
- App-store ratings and social-media sentiment.
- Marketing claims and unreleased roadmap features.
- Affiliate revenue, we accept none for the apps reviewed; subscriptions are paid at retail.
- UI polish and onboarding aesthetics, except where they affect day-30 usability.

Five factors decide whether a tracker fits you. Read each review with these in mind.
1. Logging accuracy
How close the estimates are to the truth. Our top-rated app hits ±0.9% portion error; the field ranges to ±12%. Accuracy is decisive for cutting and bodybuilding.
2. Logging friction
How fast a meal is to log. Friction is why most people quit tracking, it dominates the beginners and weight-loss use cases.
3. The right nutrients
Net carbs for keto, protein for muscle gain, micronutrients for micronutrient tracking. Check each review's macro coverage against your goal.
4. Database & cuisine coverage
Whether the app knows the foods you eat, branded goods, restaurants, international cuisines. See the restaurant-dining category.
5. Coaching & adaptivity
Whether targets adapt over time from real data. A static target eventually stops working. Compare apps directly on the comparison page.
