The 9 best apps, ranked

Ranked for a general user who wants to lose, maintain, or gain weight against a calorie target. The right app for you may sit lower on this list — a keto dieter should jump straight to Carb Manager, and a data nerd to Cronometer.

1. FindCals — best for FindTDEE readers

   Full disclosure: FindCals is our own app, built by the team behind this calculator — so weigh this placement with that in mind. We rank it first for FindTDEE readers specifically, and here’s the honest reason why. Every other app makes you re-enter your stats and guess at an activity level during setup. FindCals imports the exact TDEE, macro split, and goal you just worked out here in a single tap, so you skip onboarding entirely and start logging against the right number from day one.

   Beyond the hand-off, it covers the fundamentals you’d expect: fast food logging, protein and macro targets front and center, and a clean interface that doesn’t bury the one number you came to hit. It’s free to use, with no five-logs-a-day cap. The honest trade-offs: it’s newer than the giants here, so its food database is still growing and it has fewer third-party integrations than MyFitnessPal.

   Best for: anyone who calculated their numbers on FindTDEE and wants to start tracking in seconds. Calculate your TDEE, then send it straight over.

2. MyFitnessPal — biggest database

   MyFitnessPal is still the default for a reason. Its database tops 20 million foods, so almost anything you eat is already in there, and logging is quick once your regular meals are saved. With 200M+ users it also has the best recipe importers, integrations, and community.

   The catch: it has paywalled hard. The free tier now caps you at five food logs a day, which most people blow past by lunch, and the barcode scanner, custom macro goals, and an ad-free experience all sit behind Premium ($19.99/month or $79.99/year), with a pricier Premium+ tier above that. Because entries are user-submitted, the same food can also show very different calorie counts, so verify anything that looks off.

   Best for: most people who want the fastest path to a habit they'll keep.

3. Cronometer — most accurate

   Cronometer is the choice when data quality matters more than database size. Its entries are drawn from verified sources like the USDA rather than crowd-sourced, and it tracks more than 80 micronutrients — vitamins and minerals most apps ignore. That makes it the strongest pick for keto, vegan, or any diet where you're watching specific nutrients.

   Barcode scanning stays free, and Gold runs $10.99/month (about $49.99/year on the App Store). The trade-offs: a smaller database than MyFitnessPal and a slightly steeper learning curve.

   Best for: accuracy obsessives and anyone tracking micronutrients.

4. MacroFactor — smartest targets

   MacroFactor's pitch is its adaptive algorithm. Instead of a single up-front estimate, it watches your real intake and weight trend and recalculates your TDEE and macro targets week to week. If your loss stalls or your appetite shifts, it adjusts for you — no guilt-trip prompts when you go over.

   Built by evidence-based fitness professionals, it logs fast and the database keeps growing. The downside is the price model: no free tier at all, just a 7-day trial, then $11.99/month or about $71.99/year.

   Best for: serious lifters and dieters who want their numbers to self-correct. Pairs naturally with a TDEE calculation as a starting point.

5. Lose It! — easiest to use

   Lose It! gets the basics right. The interface is clean and friendly, the free plan is genuinely usable, and the Snap It photo-logging feature is a nice shortcut. It's the app to recommend to someone who has bounced off tracking before because it felt like a chore.

   Premium is one of the better deals here at $39.99/year. The limits show up at the edges: a smaller database than MyFitnessPal and lighter exercise and integration support.

   Best for: beginners and anyone who wants tracking to feel simple.

6. FatSecret — best free option

   FatSecret quietly has the most generous free tier in this list. Barcode scanning, a solid professional food database, meal planning, and a helpful community are all available without paying — a real advantage now that MyFitnessPal has moved its scanner to Premium.

   It does now sell a Premium tier (roughly $39–$60/year depending on your country), but most people never need it. The interface isn't as polished as Lifesum's, and it leans less on the gamified motivation some apps push.

   Best for: anyone who wants to track for free without losing the barcode scanner.

7. Lifesum — best design

   Lifesum is the best-looking app here, and that's not nothing — a pleasant interface helps you keep logging. It's strongest at structured diet plans and meal suggestions tailored to your preferences, so it suits people who want guidance, not just a blank food diary.

   Premium starts around $30.99/year (it varies by region and promotion). The trade-off is depth: the food database and macro tooling don't go as far as MyFitnessPal or Cronometer.

   Best for: people who want a guided, good-looking experience.

8. Carb Manager — best for keto

   Carb Manager is purpose-built for keto and low-carb eating. Net-carb tracking is front and center, with keto-specific insights and a large library of low-carb recipes. If you're counting net carbs rather than total calories first, this is the most natural fit.

   The free version handles basic net-carb tracking; Premium runs about $39.99/year. Outside of keto, more general apps will serve you better.

   Best for: keto and low-carb dieters.

9. AI photo trackers — handle with care

   A newer wave of apps logs meals from a photo using AI. They're fast and great for accountability, but image recognition still struggles to judge portion size, hidden cooking oils, and mixed dishes — the exact things that move a calorie count. Treat them as rough estimators, not precise trackers.

   Best for: people who'll log more often if it's effortless, and who accept a looser number in exchange.

How to choose

The best app is the one you'll open every day. Beyond that, weigh four things in this order.

• Will you actually use it? If logging feels like a chore, you'll quit. Lose It! and Lifesum win on ease; MyFitnessPal wins on speed once your meals are saved.
• Database size vs accuracy. MyFitnessPal has the most foods but user-submitted errors; Cronometer has fewer foods but verified data. Big database for convenience, verified database for precision.
• Your diet. Keto points to Carb Manager. Full nutrient profiles for a vegan or restricted diet point to Cronometer. General weight management fits the big three.
• Budget. Most apps have a free tier that's enough to lose or gain weight. Only pay once a specific feature — the barcode scanner, custom macros, adaptive targets — is something you'll genuinely use.

How accurate is calorie tracking?

The app's database is rarely your biggest source of error — you are. Studies consistently find people underestimate their intake by 20 to 30 percent, mostly from eyeballed portions and forgotten extras. A verified database like Cronometer's narrows the gap, but no app can fix a guessed portion size.

Two habits fix most of it. First, weigh solid foods on a kitchen scale instead of using cups or estimates — grams are far more accurate. Second, log everything, including the oil you cooked in and the bites off someone else's plate. Do that, and even a free app gets you within a useful margin.

Using an app with your TDEE

A calorie app answers “did I hit my number?” — not “what should my number be?” That part comes from your TDEE. Set the target first, then let the app hold you to it.

1. Calculate your TDEE

   Get your maintenance calories from the FindTDEE calculator. Most in-app calculators use one basic formula and a vague activity slider, which can be off by hundreds of calories.

2. Set a custom goal in the app

   During setup, choose “custom” or “manual” rather than letting the app guess. Subtract for fat loss or add for muscle gain — a 250–500 calorie deficit for losing, a 200–500 surplus for gaining. See how to lose weight for the full method.

3. Enter your macros

   Split your target into protein, carbs, and fat with the macro calculator, then plug those numbers in. Hitting protein is what protects muscle while you diet.

4. Track two to three weeks, then adjust

   Log honestly and watch the scale trend, not single days. If results don't match the target after a couple of weeks, adjust by 100–200 calories — or check your logging first, since under-counting is the usual culprit.
