Best Free Macro Tracking App in 2026: 8 Apps Compared

MyNetDiary earns the top spot for free macro tracking because the everyday jobs are free. You can set protein, carbohydrate, and fat targets in grams or as percentages, scan barcodes, log water, and see up to 108 nutrients per entry where data exists, all without paying and without ads. That combination is rare in this category, where a scanner or a gram target is often the first feature moved behind a paywall.

The paid tiers still add value. Premium, at $59.99 per year, adds Meal Scan photo logging, recipe import, and advanced autopilot targets, while Premium Plus, at $99.99 per year, adds an AI coach. If you do not need those extras, the free tier covers the core job well. One practical note: starting without an account is easy, but back up your data with an account so a lost phone does not mean a lost history.

Cronometer is the best free macro tracking app for people who want to see beyond protein, carbs, and fat. Its free tier tracks up to 84 nutrients, uses verified food entries rather than a mostly crowdsourced list, and includes barcode scanning at no cost. A full web app is also available, which helps if you prefer logging on a computer at the end of the day.

Gold, at $59.99 per year, removes ads and adds photo logging, voice logging, custom charts, and a macro scheduler for different targets on different days. The free interface can feel dense at first because so much nutrient detail is on screen. If you only care about three macro numbers, MyNetDiary is simpler, but if a vitamin or mineral gap is your real question, Cronometer is the stronger free choice.

MyFitnessPal remains useful because its food database is enormous, with more than 20 million entries, including many restaurant dishes and branded products that smaller databases miss. Free users can search foods, log meals, view macros, track weight, and connect many fitness apps and devices. If you eat a lot of packaged or restaurant food, that breadth can save time, even if some entries are user-submitted and need a second look.

The free limits matter for macro tracking. Percentage macro goals are free, but gram-based goals, per-meal macro targets, barcode scanning, Meal Scan, and voice logging sit in Premium, at $79.99 per year, with Premium Plus at $99.99 per year adding meal planning. Try the free tier first with foods you eat often. If you find yourself typing every packaged item by hand, compare that daily friction with the Premium price.

Lose It suits first-time trackers who want a simple daily budget rather than a wall of nutrient charts. The free tier covers basic food logging, a calorie budget, weight logging, and a basic macro view, and its social features, including challenges and groups, help some people stay consistent. The diary is easy to read at a glance, which is a real strength when logging feels like a chore.

For serious macro work, the paywall arrives sooner. Custom macro targets, per-meal macro views, barcode scanning, photo logging, and device syncs sit in Premium. Recent listings put Premium at $79.99 per year in some comparisons and $39.99 per year in others, so check the price inside the app before you decide. If your goal is mainly a calorie budget with a rough macro split, the free tier is enough.

FatSecret is a strong free pick for packaged-food shoppers because its barcode scanner and core macro tracking are free. You can log food, track weight and exercise, and use community features without paying, and the app supports many languages. For someone whose main question is if a supermarket item fits their protein target, that free scanner is the deciding feature.

Premium, at $59.99 per year in US app store listings, adds photo logging, quick logging tools, water tracking, and dietitian-designed meal plans. The free interface is less polished than MyNetDiary or Cronometer, and some ways of saving and repeating whole meals sit in Premium. Check the serving size on scanned items against the label, since a scanner identifies a product but does not measure your portion.

Carb Manager is the best free macro tracking app for low-carb and keto eaters because net carbs are central to its design, not an add-on. The free tier covers daily macro targets, food logging, and fasting tracking, and it does not show third-party ads. That focus helps when your main daily question is how many net carbs remain, rather than a general calorie total.

Premium, at $39.99 per year, adds per-meal targets, day-of-week targets, and deeper analysis. The food database is smaller than MyFitnessPal or Lose It, so unusual branded items may need manual entry. If you follow a standard balanced diet, a general tracker may fit better, but for keto and low-carb plans, Carb Manager's free setup is hard to beat.

MacroFactor is not a free app, and we include it because many people searching for the best free macro tracking app end up comparing it with free options. It costs $11.99 per month, $47.99 for six months, or $71.99 per year after a 7-day trial. What you pay for is its expenditure algorithm, which estimates your energy needs from logged intake and weight trend and adjusts calorie and macro targets each week.

That coaching only works if you log most days and weigh in regularly. Skip logging for a week and the algorithm has little to work with. There is also no web app, so logging happens on a phone, and micronutrient tracking is thinner than Cronometer. Choose MacroFactor if you want structured cutting or bulking phases with weekly adjustments, not if you need a free diary.

Carbon Diet Coach is another paid coaching app that often appears in free macro app searches, so it is worth placing honestly. It costs $11.99 per month, $59.99 for six months, or $99.99 per year, with no ongoing free tier. Each week you check in, report your results, and Carbon adjusts your macros, which suits people who stall on a fixed target and want a clear next step.

Carbon includes a food tracker, but it does not offer meal planning, and its database is verified and therefore smaller than crowdsourced rivals. That trade can mean more manual entries for unusual foods. If you want a coach that tells you what to change next week, Carbon is a good fit. If you want a free diary, start with MyNetDiary or Cronometer instead.
