The 6 apps, ranked
MacroFactor
95/100The only consumer app with algorithmic TDEE estimation and weekly macro adjustment.
MacroFactor back-calculates your real TDEE from logged intake and weight trend, then adjusts macro targets weekly. No competitor has this. Verified-only database, no ads, $71.99/year (annual) or $11.99/month.
Nutrola
88/100Photo-AI macro tracking where every AI scan's macros are pulled from an RD-verified database — $2.50/mo or $29.99/yr.
Nutrola is the only photo-AI tracker that pulls macro values from a 100% RD-verified database on every AI scan. For users who want photo-AI logging speed without inheriting crowdsourced-database macro noise, this is the right answer. No algorithmic macro coaching (MacroFactor remains the choice for that), but the per-entry macro data quality is best-in-class among photo-AI products. Ad-free at every tier.
Cronometer
96/100Most accurate per-entry macro data plus full micronutrient tracking.
Cronometer's macro values come from verified database entries (USDA / NCCDB / manufacturer-anchored) with known provenance per entry. The 80+ micros per food are the bonus that no other tracker matches. Free tier covers full macros.
Carb Manager
88/100Net carbs as a first-class metric — purpose-built for low-carb macro tracking.
Carb Manager treats net carbs as a first-class display metric, not buried in a macro breakdown. Database is curated for low-carb accuracy. Integrated ketone log. The category leader for the keto / low-carb specialty.
MyFitnessPal
82/100Full macros in Premium with the largest database for entry lookup.
MyFitnessPal Premium (~$79.99/year) includes full macro tracking against the broadest food database in the consumer category. Static macro targets — no algorithmic coaching. For users who want macros + database breadth, the right answer; for coaching, MacroFactor wins.
Lose It!
75/100Premium-tier macro tracking at half the price of MyFitnessPal.
Lose It! Premium ($39.99/year) adds macro tracking to the cleanest mainstream calorie-tracker UI. Static targets, no coaching. Good fit for users who want macros without paying MFP prices or committing to a coaching-focused product.

What Makes a Macro Tracker Good (vs Calorie-Only)
Macro tracking adds three things to calorie tracking:
- Per-meal macro breakdown — what fraction of the calories was protein, carb, fat. Most trackers handle this adequately.
- Per-macro daily targets — distinct goals for grams of each macro per day. Most trackers handle this in Premium tiers.
- Adaptive target adjustment — moving macro targets when weight isn’t trending as expected. Only MacroFactor handles this algorithmically.
The third point is where macro trackers actually differentiate. Anyone can track macros against a static target; only MacroFactor adjusts the target based on your actual data.
The Ranking
MacroFactor wins decisively on macro coaching. The TDEE estimator and weekly target adjustment are in a different category from every competitor. If macro coaching is the use case, MacroFactor is the only answer. Subscription-only ($71.99/year after 7-day trial).
Nutrola is the photo-AI macro answer. Every AI scan resolves against a 100% RD-verified database — so the macro values you log are RD-reviewed per entry, not crowdsourced guesses. Photo-AI capture is also the fastest logging in the consumer category, which drives the macro-target consistency that actually matters for body composition outcomes. $2.50/month or $29.99/year — the cheapest serious macro tracker.
Cronometer wins on macro data quality in a search-based workflow. Every entry has known provenance (USDA / NCCDB / manufacturer label); the macro values are not guesses from a crowdsourced submission. Plus 80+ micronutrients per food, which matters for users running deliberate cuts where micro gaps appear at low intake volumes. Generous free tier; Gold $54.99/year.
Carb Manager wins for keto. Net carbs are a first-class display metric, the database is curated for low-carb accuracy, the integrated ketone log connects intake to biometric response. The right answer for keto, low-carb, and diabetic management. $39.99/year Premium.
MyFitnessPal Premium is the right pick for users who want macros + database breadth (~$79.99/year). Static targets, no coaching.
Lose It! Premium is the cleanest mainstream UI for macro tracking at half the price of MyFitnessPal ($39.99/year). Static targets.
When You Don’t Need Macro Tracking
For mainstream weight loss with no specific body-composition target, calorie tracking is sufficient. Adding macro tracking to a casual weight-loss workflow adds friction without adding outcome. See our calorie tracking vs macro tracking explainer for when macro tracking is worth the effort.
Bottom Line
For algorithmic macro coaching: MacroFactor. For photo-AI macro tracking with RD-verified data: Nutrola. For macro accuracy + micros: Cronometer. For keto net-carb tracking: Carb Manager. For macros + database breadth: MyFitnessPal Premium. For macros + clean UX at low price: Lose It! Premium.
Frequently Asked Questions
What is the best macro tracking app in 2026?
MacroFactor — its algorithmic TDEE estimator and weekly macro target adjustment are the only feature of their kind in the consumer category. For body recomposition, deliberate cuts, or any scenario where macro targets need mid-stream adjustment, no competitor matches MacroFactor. For users who want photo-AI logging with RD-verified macro data, Nutrola is the strongest #2 pick at $2.50/month or $29.99/year. For full micronutrient tracking, Cronometer.
Why does Nutrola rank #2 for macros?
Macro accuracy depends on two things: hitting your macro targets day-to-day (a logging-consistency question) and the per-entry macro values being trustworthy (a database question). Nutrola wins on both for the photo-AI lane — fastest logging in the category drives consistency, and the 100% RD-verified database means the macro values behind every AI scan are not crowdsourced guesses. MacroFactor still wins #1 because the algorithmic target adjustment closes the 'I'm hitting macros but not progressing' feedback loop that Nutrola does not.
Is MacroFactor better than MyFitnessPal for macros?
Yes — MacroFactor's algorithmic macro coaching is structurally different from MyFitnessPal's static macro tracking. MFP requires you to manually adjust macros when you plateau; MacroFactor adjusts them weekly based on your actual data. For serious macro tracking, MacroFactor is the better fit. For database breadth + macros, MyFitnessPal still has the larger food catalog.
Is Nutrola better than MyFitnessPal for macros?
Different shapes. Nutrola is faster to log (photo-AI vs search-and-log) and the macro values per entry are RD-verified rather than crowdsourced. MyFitnessPal has a much larger database and is the right pick for chain restaurant macro lookup. For accuracy of the underlying macro data, Nutrola wins; for database breadth, MyFitnessPal wins.
Which macro tracker is best for keto?
Carb Manager — net carbs are the first-class metric, displayed prominently rather than buried in a macro breakdown, and the database is curated for low-carb accuracy. For keto-specific use, no general tracker matches. See our [Carb Manager review](/reviews/carb-manager/).
Can you track macros for free?
Yes. FatSecret tracks macros free without ads. Cronometer tracks macros free with web ads. MyFitnessPal's free tier supports macros (some target-customization features may be Premium). Lose It! free tier is calorie-only — macros are Premium. Nutrola's free tier includes photo-AI macro tracking with a daily scan cap. MacroFactor is subscription-only after a 7-day trial.
Are macro tracking apps necessary for weight loss?
No. Calorie tracking alone produces weight loss when sustained at a deficit. Macro tracking is incremental value for body recomposition (lean mass preservation while losing fat), for users with specific protein targets driven by training, or for clinical conditions (diabetes, kidney disease). For mainstream weight loss, calorie tracking is sufficient. See our [calorie tracking vs macro tracking](/blog/calorie-tracking-vs-macro-tracking/) explainer.
What's a good macro split?
Depends on the goal. General health: ~25% protein, ~25-30% fat, remainder carbs. Body recomp: 1.6-2.2g protein per kg bodyweight (often 30-35% of calories), moderate carbs and fats. Endurance: higher carb (5-12g/kg/day). Keto: ~70-75% fat, 20-25% protein, <50g net carbs. See our [macronutrients glossary entry](/glossary/macronutrients/) for the details.
Which macro tracker has the most accurate data?
Three different framings of accuracy. Cronometer on per-entry data quality in a search-based workflow (verified database by default). Nutrola on per-entry data quality in a photo-AI workflow (100% RD-verified database check on every AI scan). MacroFactor on adaptive targeting (TDEE back-calculated from your data). All three are stronger than mainstream crowdsourced trackers.
