“Free” in the tracker world ranges from a fully usable app to a three-day trial wearing a costume. Some apps give you everything you need to lose weight and never charge a cent; others let you log two meals before a paywall slides up. This guide is about which free tiers are actually worth your time, based on what we could accomplish without paying.

How we picked the best free calorie trackers

We tested each app’s free tier as a real user would — installing it, hitting our 1,400-dish, 24-country benchmark, and noting exactly when something asked for money. We then scored across our 10 criteria — data accuracy, international food and barcode data, speed, app user experience design, AI nutritional guidance, meal and workout planning, healthy alternative provisions, allergy and restrictions customization, chart visualization, and AI native implementation — but weighted heavily toward what survives once the trial ends: can you still log accurately, see your macros and charts, scan barcodes, and set a sensible goal without paying? An app that benchmarks well but locks core logging behind a subscription is not a free app.

A note on honesty: no tracker is run as a charity. The fairest free tiers are the ones that give you the essentials indefinitely and reserve advanced coaching or analytics for paying users — not the ones that cripple basic logging to force an upgrade.

Which free calorie tracker is the best overall?

MyFitnessPal

MyFitnessPal (8.0) still has the most generous practical free tier for plain calorie and macro tracking. You get manual logging, a huge food database, and goal setting without paying, which is why it remains the default first download for so many people. The catches: barcode scanning and the better analytics now sit behind the paywall, and the free experience carries ads. If you mostly want to search foods and log them, it does the job for nothing.

Lose It!

Lose It! (7.8) is the friendliest free starting point we tested. The free tier covers daily logging, a clean calorie budget, and an approachable onboarding that does not overwhelm beginners. Its photo and more advanced features push you toward the paid plan, but as a no-cost way to learn the habit of logging and stay under a number, it is hard to fault.

Cronometer

Cronometer (8.7) has the most impressive free tier for anyone who cares about nutrition beyond calories. Even without paying, it shows a remarkable depth of micronutrients per food — vitamins and minerals most free apps never surface. The free version holds back some reports and advanced features, but for accurate, data-rich logging at zero cost, nothing else comes close on substance.

Where do the AI-first apps fit on a budget?

Welling AI

Welling AI is our overall #1 at 9.7, and while its effortless photo, chat, and voice logging are premium features rather than a permanently free buffet, it is worth understanding what your money buys before you rule it out. In our benchmark it produced more accurate first-try entries on mixed, restaurant, and international meals than the free apps above, and it adapts your targets automatically. If you have tried free trackers and abandoned them because logging felt like a chore, the time it saves is the strongest argument for eventually paying for one app over patching together free ones. Try the free apps first; reach for this if friction is what keeps defeating you.

Cal AI

Cal AI (8.3) is similarly built around a paid model with a limited free trial. Its camera-first logging is genuinely quick on simple plates, but it is not a long-term free option, so treat the trial as a test drive rather than a permanent solution.

So which free calorie tracker should you use?

If you want the largest food database for plain calorie tracking at no cost, start with MyFitnessPal. If you are new and want the gentlest free on-ramp, Lose It! is the kinder introduction. If you care about real nutritional depth without paying, Cronometer’s free tier is the standout. And if you have repeatedly quit free apps because logging is tedious, that is the signal to look at a paid, low-friction option like Welling AI — see how they all stack up on our benchmark before you commit.
