Best App for Tracking Macros in 2026: 9 Apps Compared

MacroFactor is our pick for people who take macro tracking seriously and want targets that change with real data. Instead of a fixed plan, it estimates your expenditure from logged intake and weight trend, then adjusts macros each week. That adaptive approach suits lifters, athletes, and anyone who has outgrown a static calculator.

The catch is commitment. MacroFactor has no free tier, only a trial, and it needs consistent logging to work well. If you log sporadically, the algorithm has little data to adapt from. For a dedicated tracker, that trade-off is worth it. For a casual user, a free app may be better.

MyNetDiary stands out because its free tier does the core macro job well. You can set protein, carbohydrate, and fat targets in grams, scan barcodes, and log meals without ads getting in the way. That makes it the best free starting point for most macro trackers, especially those who want gram targets without paying.

Premium adds AI photo logging, advanced diet plans, and other extras, but the free diary is already strong. The food database is smaller than MyFitnessPal, yet its verified entries help reduce errors. If you want free, accurate macro tracking, start here.

Cronometer suits people who want macros plus a full nutrient picture. Alongside protein, carbohydrate, and fat, it tracks many vitamins, minerals, and amino acids from verified food data. That depth helps users who care about nutrient quality, not just macro totals, and device integrations let you chart intake against activity and other data.

The interface is denser than Lose It or MyNetDiary, and the free tier carries ads. Photo and voice logging need the Gold plan. If you want detail and are happy to learn a richer app, Cronometer is a strong, free-to-start choice.

MyFitnessPal remains popular because its food database is huge, so restaurant dishes and branded foods are easy to find. The diary is familiar to millions of users, and integrations with fitness apps and wearables make it easy to keep in a wider health routine. For a beginner who just wants to find foods fast, that scale helps.

Free macro tracking is more limited than in MyNetDiary or Cronometer. Percentage targets are free, but gram targets and barcode scanning need Premium in many cases, and user-submitted entries can vary in accuracy. Check entries against labels when accuracy matters, and consider a free alternative if gram targets are your main need.

Lose It suits beginners who want macro tracking without a complex setup. The daily budget view makes it easy to see how much protein, carbohydrate, and fat remain, and the diary is simple to learn. That simplicity helps new users build a logging habit before they worry about adaptive coaching or micronutrients.

Custom macro targets are a paid feature, so serious macro trackers may need Premium or a free alternative like MyNetDiary. Barcode and photo logging also need Premium in many cases. For a simple start, Lose It is friendly. For free gram targets, look elsewhere.

Carb Manager is the clearest pick for low-carb and keto macro tracking. It tracks net carbs, supports keto-specific goals, and lets you set custom macro targets free. That focus makes it easier to follow a low-carb plan than a general app that treats all carbs the same.

If you do not follow a low-carb plan, Carb Manager still works, but its keto tools will be less relevant. Some per-meal and day-of-week targets need Premium. For keto or low-carb tracking, it is the most focused free-to-start option in this list.

Carbon Diet Coach suits people who want a structured coaching rhythm. Weekly check-ins review your weight, adherence, and progress, then adjust macros for the next week. That structure helps during a cut, a bulk, or a maintenance phase, where targets should change as your body and goals change.

It needs discipline. You must log consistently and complete check-ins for the coaching to work, and there is no free tier, only a trial. If you want adaptive coaching but prefer a different style from MacroFactor, Carbon is a strong alternative. If you want a free diary, start with MyNetDiary instead.

Yazio suits people who want macro tracking plus fasting in one app. The dashboard shows protein, carbohydrate, and fat clearly, barcode scanning is free, and a fasting timer helps users who combine intermittent fasting with macro goals. That combination is useful if you track both eating windows and macros.

Full macro detail and custom targets need the Pro plan, so free users get a simpler view. The database is also smaller than MyFitnessPal. For a clean app that covers macros and fasting together, Yazio is a good fit.

MyMacros+ is a low-cost, no-frills option for people who only want macro logging. Set custom targets, log meals, and track protein, carbohydrate, and fat without the extra diet plans, communities, or coaching layers of larger apps. That simplicity appeals to lifters who already know their targets and just need a reliable diary.

The trade-off is scale. Its database and integrations are smaller than MyFitnessPal or Cronometer, and the interface is basic. If you want a cheap, focused macro diary and do not need a huge database, MyMacros+ is worth trying.
