Best Protein Tracker App in 2026: 7 Apps Compared

#1

MyFitnessPal

Best for: Anyone who wants the largest food database and the most integrations

Visit myfitnesspal.com

MyFitnessPal is still the default calorie tracker, mostly because of the database: with over 20 million foods logged over two decades, almost anything you eat has an entry. That matters for protein tracking specifically, because the biggest source of error in macro totals is logging the wrong food entry. The Premium tier at $79.99 per year (or $19.99 monthly, per the vendor's own pricing materials) adds barcode scanning, custom macro goals in grams, meal scan photo logging and an ad-free experience; Premium+ at $99.99 per year adds meal planning.

The 2026 reality is the paywall. Barcode scanning, the single most-used feature, now sits behind Premium, and the free tier covers basic logging with ads. The crowdsourced database is both the strength and the weakness: huge, but full of duplicates with conflicting numbers. If you eat a lot of packaged and restaurant food and want the fastest logging, MyFitnessPal earns its price. If you mostly cook whole foods and want accuracy, Cronometer below gives you more for free.

#2

Cronometer

Best for: People who want detailed nutrition data, including micronutrients, without paying

Visit cronometer.com

Cronometer is the nutrition nerd's pick and the most generous free tier in this category. Where MyFitnessPal's free version shows five numbers, Cronometer's free version tracks dozens of micronutrients: individual amino acids, vitamins, minerals, omega fatty acids. Every database entry is verified against USDA or NCCDB sources or reviewed by the curation team, so the protein number you log is one you can trust. Barcode scanning is free, custom macro goals are free, and there are no scan limits.

The vendor does not publish Gold pricing on its public pages, so we list "See website"; third-party comparisons put Gold around $59.99 per year for ad-free use, photo and voice logging, and advanced reports. The interface is unapologetically data-dense, which delights detail people and overwhelms everyone else. For protein tracking with a accuracy-first mindset, and especially for anyone managing deficiencies or specific diets, Cronometer's free tier beats most competitors' paid tiers.

#3

MacroFactor

Best for: Lifters and athletes who want macro targets recalculated from their own data

Visit macrofactorapp.com

MacroFactor does something the loggers above do not: it coaches. You log your food and your weight, and its algorithm estimates your true energy expenditure, then adjusts your calorie and protein targets every week based on what actually happened, not what a formula predicted. Miss your targets and there are no red warnings or scolding; the plan simply adapts. The subscription is $11.99 per month, $47.99 per half year or $71.99 per year (per the official app store listings), with a 7-day free trial and no free tier.

That adaptive loop is why lifters swear by it: static macro calculators go stale within weeks as your body adapts, while MacroFactor's targets track your reality. The food database is verified, barcode scanning is included, and the interface is clean. The obvious catch is the price of admission: $71.99 a year with no free tier means you are buying on reputation. If you want a tracker that thinks, this is it. If you just want to log protein grams, the free apps above do that for nothing.

#4

Lose It

Best for: Beginners who want simple calorie and protein tracking without complexity

Visit loseit.com

Lose It has been doing one thing since 2008: giving you a daily calorie budget and making it fast to stay inside it. The interface is the simplest on this list, which is a feature, not a gap: set your goal, log by barcode, photo (Snap It) or voice (Say It), and watch the budget. Premium runs about $39.99 per year per reviewers, adding the scanner, smart camera, advanced nutrient tracking and pattern reports, and the app itself is free to download with a usable free tier.

For protein specifically, Lose It covers the essentials: macro tracking with personalized protein goals, without the 84-nutrient firehose of Cronometer. It will not adjust your targets from your weight trend like MacroFactor, and its database is smaller than MyFitnessPal's. But at $39.99 a year it is the cheapest paid upgrade here, and for someone starting their first serious protein goal, simplicity beats depth. Try the free tier for two weeks; if the ads and limits annoy you, Premium is the smallest bill on this list.

#5

MyMacros+

Best for: People who want to pay once and never see a subscription bill

Visit getmymacros.com

MyMacros+ is the last of a dying breed: a nutrition app you buy once. No subscription, no ads, no premium tier upsells. Reviewers report a one-time price around $4.99, though the vendor's homepage does not publish current pricing, so we list "See website." What you get is a complete macro tracker: a 5-million-food database, barcode and nutrition label scanning, unlimited custom meals (no breakfast-lunch-dinner straitjacket), macro goals in grams, and offline tracking.

There is no coaching layer. It will not adjust your protein target from your weight trend, detect your chords, or sync with forty devices. It logs what you ate and shows your macros, fast, forever, for the price of a coffee. For lifters who know their targets and just need a reliable logger without a monthly bill, that is the whole appeal. The tradeoff is a smaller development team and an interface that looks its age next to the big budgets. If subscriptions offend you on principle, this is your app.

#6

Carbon Diet Coach

Best for: Dieters who want evidence-based macro coaching with weekly check-ins

Visit joincarbon.com

Carbon Diet Coach is the other coaching-first app here, and its pitch is credibility: the system was built by nutrition scientists including Layne Norton, PhD, around flexible dieting and energy balance. You set a goal (fat loss, muscle gain, maintenance, reverse dieting), log your food, and check in weekly; the coach adjusts your macros based on your actual progress. Pricing is published right in the vendor's FAQ: $11.99 per month, $59.99 for six months, or $99.99 per year, with full features on every plan.

The food tracker itself is deliberately simple; the value is the coaching loop, not the database. That loop only works if you check in consistently, so casual loggers will not get their money's worth. There is no free tier. Compared with MacroFactor ($71.99/year), Carbon costs more annually but leans harder on the science-backed coaching brand and human support. Pick Carbon if you want a coach in the evidence-based dieting tradition; pick MacroFactor if you want the slicker algorithm at a lower price.

Easy Diet Diary

Best for: Australians who want a free tracker with a local food database

Visit easydietdiary.com

Easy Diet Diary is a free, ad-free diet tracker built by Xyris, the Australian company behind the professional FoodWorks nutrition software. The vendor's site states it plainly: free and ad-free, with all features included. The standout is the Australian food database built from official sources and local brands, which is exactly what global apps get wrong down under. Barcode scanning, macro and micronutrient tracking, exercise logging and kilojoule-or-calorie display are all included, and you can share your diary directly with a dietitian through FoodWorks.

The honest limitation is geography. Outside Australia and New Zealand, the local database advantage disappears, and the big global apps have deeper integrations and larger communities. But for its home audience it is remarkable: a genuinely free tracker with professional-grade data and no upsell. Australian readers chasing a protein target should start here before paying for anything. Everyone else should treat it as proof that free trackers can be excellent, then pick from the global options above.
