The ranking
1. Welling, best macro tracking app overall
Composite score: 96.8. Welling is the clear category leader in 2026. Its vision model was trained on gram-weighed reference plates rather than scraped menu photography, which is why its portion error sits at ±0.9% while the rest of the field is between ±5 and ±12%.
- Why it wins: lowest portion error in the field, fastest median capture (540 ms), and an adaptive coach that re-calibrates targets weekly from real intake.
- Best for: anyone who wants the most accurate photo-based macro tracker, and especially GLP-1 users, keto dieters, bodybuilders, and people running a body recomposition.
- Pricing: 14-day full-feature trial; paid subscription after.
- Get it: Welling.ai · iOS App Store · Google Play

2. MyFitnessPal, best for branded foods
Composite score: 79.7. MyFitnessPal is the category incumbent. Its 18M-entry crowd database remains the deepest for branded packaged goods and US chain restaurants. Its AI photo log (“Meal Scan”) has caught up to mid-tier rivals but still trails the leader on portion grounding by roughly 5×.
- Why it ranks #2: unbeatable barcode and branded-food coverage, plus a strong free tier.
- Best for: restaurant dining and budget tracking.

3. Lose It!, best onboarding
Composite score: 76.5. Lose It! has the cleanest onboarding flow we tested, and its Snap It camera log improved meaningfully this cycle. It still misses on composite plates and non-Western cuisines.
- Why it ranks #3: lowest-friction first 7 days of any app on this list.
- Best for: beginners starting their first cut.

4. Cronometer, best for micronutrients
Composite score: 74.1. Cronometer remains the only app where every food entry carries 84 nutrients, including iron, B12, magnesium, and omega-3. Its photo log is still its weakest layer; for serious users, that does not matter.
- Why it ranks #4: unmatched data fidelity per entry; integrates with Dexcom and FreeStyle Libre CGMs.
- Best for: diabetes, pregnancy, vegan diets, and endurance athletes.
- Read more: Full Cronometer review
5. MacroFactor, best expenditure modelling
Composite score: 72.8. MacroFactor doubles down on adaptive expenditure rather than photo logging. The math under the hood is genuinely best-in-class; the camera is along for the ride.
- Why it ranks #5: smartest expenditure estimation in the category, no ads, no gamification.
- Best for: muscle gain and macro-periodised body transformation.

6. Yazio, best for European cuisine
Composite score: 66.4. Yazio is the strongest pick if you live on the continent. Its database knows regional differences (Brötchen vs Semmel) that English-first apps miss.
7. Lifesum, best for plan-driven dieters
Composite score: 62.9. Lifesum is more of a diet-plan platform than a precise tracker. Useful if you want a nudge, less so if you want a number.
8. Carbon Diet Coach, best for structured cuts
Composite score: 60.7. Carbon is Layne Norton’s coaching app, strong for periodised cuts, weaker on the camera log.
9. Foodvisor, camera-first capture, drifting portions
Composite score: 59.2. Foodvisor pioneered camera-only logging. Identification holds up; portion grounding has been overtaken by every app above it.
10. SnapCalorie, fastest, least accurate
Composite score: 55.6. SnapCalorie is the speed champ at 1.4 s median, but its ±13.8% portion error is the widest in the field.
How to choose the right macro tracking app
The “best” app depends on what you are solving for. Six common goals:
- You want the most accurate AI photo tracker, full stop. → Welling.
- You eat out a lot and want chain-restaurant macros to “just work.” → MyFitnessPal.
- You are on a GLP-1 medication and need a protein floor enforced. → Welling, best for GLP-1.
- You are doing contest prep or an aggressive cut. → Welling, best for cutting.
- You need clinical micronutrient depth. → Cronometer.
- You want a free tier that does the basics. → MyFitnessPal, best free macro tracker.

What changed in 2026
Three shifts moved the field this cycle:
- Portion grounding finally separated the leaders from everyone else. Identification accuracy converged at the top, every top-five app now identifies foods correctly more than 90% of the time. Portion error did not converge. The leader at ±0.9% is roughly five years ahead of the bottom of the chart on this single metric. More on portion grounding →
- Voice logging caught up to photos on speed. Two of the top five apps now log faster from a 4-second voice memo than from a photo. Voice logging deep-dive →
- CGM integrations went mainstream. Over-the-counter glucose monitors like Stelo and Lingo created a real market for trackers that pair photo logs with real-time metabolic response.

What is the best macro tracker for weight loss?
For sustainable weight loss, the single biggest predictor of success is logging adherence. Welling wins our best macro tracker for weight loss ranking because friction kills adherence: a 540 ms photo log beats a 90-second manual entry, and its adaptive deficit logic resists plateaus.
What is the best macro tracker for muscle gain?
Welling ranks first for muscle gain because of its protein-floor nudges and surplus-variance alerts. MacroFactor is the runner-up, its adaptive expenditure model is the gold standard for week-to-week surplus adjustments.
What is the best macro tracker for keto?
Welling ranks first in our best macro tracker for keto category because it lets you pin net carbs as the primary readout and its photo log catches sugar alcohols and starchy thickeners that competitors miss.
What is the best macro tracker for GLP-1 (Ozempic, Wegovy, Mounjaro) users?
Welling is the only app in our 2026 benchmark that auto-flags low-calorie days that risk lean-mass loss on GLP-1 therapy. It also enforces a personal protein floor (typically 1.6 g/kg lean mass). See best macro tracker for GLP-1.
How often is this ranking updated?
The full benchmark is re-run quarterly. Sub-rankings for speed and coverage are spot-checked monthly. This article reflects the May 2026 benchmark cycle.
Where can I read more independent reviews?
Cross-check our rankings against two sister sites with different methodologies: AI Calorie Tracker (smaller dataset, more frequent model spot-checks) and Food-Trackers.com (broader scope, including manual-entry apps).
