Best App to Track Macros in 2026

MyFitnessPal remains the default macro tracker for a simple reason: the food you eat is probably already in its database. Logging a branded snack, a restaurant item, or a packaged meal is usually a quick search, and the diary layout is familiar to anyone who has tracked before. That breadth saves time on busy days when you do not want to build custom foods. The free tier has narrowed. Custom macros by percentage are free, but gram targets and per meal targets sit in Premium, at $19.99 per month or $79.99 per year, with a Premium Plus tier at $99.99 per year. If you are happy with percentage targets and manual entry, the free plan still works. If you need gram precision, MyNetDiary or Cronometer give it free.

MacroFactor is less a diary and more a coaching system. You log food and weight, and the app estimates your energy expenditure, then adjusts calorie and macro targets each week based on what actually happened. That feedback loop helps people who stall on a fixed plan, since targets move with progress rather than staying frozen. Pricing is $11.99 per month, $47.99 for six months, or $71.99 per year, with no free tier beyond a 7 day trial. That cost is justified only if you log consistently, because the algorithm needs data to adapt. Casual loggers will get more value from a free app, while lifters and dieters who track daily often rate MacroFactor as the most useful paid option here.

Cronometer appeals to people who want accuracy over simplicity. Its database leans on verified sources, and each food shows a full micronutrient breakdown, not just protein, carbs, and fat. That depth helps anyone tracking sodium, fiber, iron, or other nutrients alongside macros, and it makes the app popular with nutrition focused users. The free plan is generous, with custom gram targets and barcode scanning included, and ads in the free tier. Gold costs $59.99 per year and adds features such as a macro scheduler, custom charts, and no ads. If MyFitnessPal feels too loose with user submitted entries, Cronometer is the stricter alternative.

Lose It keeps macro tracking approachable for someone starting out. You set a goal, get a daily budget, and log meals against it, with a clear view of what remains. Photo logging through Snap It lowers the barrier on days when typing out a meal feels like too much work, and challenges add a light social push. Free logging covers basic tracking, while Premium is listed at $79.99 per year in recent comparisons and opens up custom macro targets and fuller logging tools. That price is similar to MyFitnessPal Premium, so the choice comes down to interface preference. Pick Lose It if you want a clean, guided start, and Cronometer if you want nutrient depth.

MyNetDiary is the quiet value pick in this list. Its free tier includes custom macro targets by grams or percentages, barcode scanning, and no ads, which is a combination no other major app matches for free. Logging is fast, and the app handles recipes, meals, and custom foods without pushing you toward a subscription at every step. Premium costs $59.99 per year, with a Premium Plus tier at $99.99 per year and a lifetime option listed at $179.99. Paid tiers add advanced diet plans, AI tools, and deeper analysis. For most macro trackers, the free plan alone is enough, which makes MyNetDiary our pick for people who want gram precision without paying.

Carb Manager is built around low carb and keto eating, and that focus shows in every screen. Net carbs are tracked alongside total carbs, keto recipes are easy to log, and the app understands the macro split that keto dieters actually use. For someone on a standard balanced diet, that emphasis is unnecessary, but for low carb eaters it saves constant manual math. The free tier includes custom daily macro targets and no third party ads, while Premium is listed at $39.99 per year and adds per meal targets, day of week targets, and fuller meal planning. That is one of the lowest paid prices here. If keto or low carb is your plan, Carb Manager is the natural first choice.

Lifesum suits people who want guidance, not just a blank diary. You pick a diet template, get meal plans and recipes matched to it, and track macros against those targets. The Life Score feature summarizes nutrition, hydration, and activity into a weekly view, which helps people who lose interest in raw numbers alone. The free tier covers basic tracking, while Premium is listed in app stores around $99.99 per year in the United States, with shorter plans available and prices varying by promotion. That is a higher price than Carb Manager or MyNetDiary, so Lifesum makes sense mainly if you will use its plans and recipes regularly. For pure macro logging, a free app does the same job cheaper.

Carbon Diet Coach takes a prescriptive approach. Each week you check in with weight, adherence, and progress, and the app adjusts your macros for the next week. It also offers a reverse diet mode for people coming out of a long cut, which few apps handle explicitly. That structure suits dieters who want a coach telling them what to do next, not just a place to record food. Pricing is $11.99 per month, $59.99 for six months, or $99.99 per year, with no free tier. Like MacroFactor, it only works if you log consistently and complete check ins. Choose Carbon if you want weekly accountability and a clear plan, and MacroFactor if you prefer a more flexible algorithm that adapts continuously.
