"Free" hides a lot of asterisks in this category, so let us be precise. If your one rule is never pay a cent, two apps stand out and it is not particularly close: Cronometer, which hands you verified data, full micronutrients, and barcode scanning for nothing, and FatSecret, which gives away almost the whole logging workflow. Those are the free champions, and the rankings below stay honest about it. Our own pick for how logging should feel is Joules, built around a photo, a daily health score, and a calm ad-free screen. After that it gets choosy: MyFitnessPal is free but paywalled its barcode scanner, YAZIO hides your macros unless you pay, and Lifesum keeps most of the good parts in Premium. Here is what each one actually gives you for free.
Our pick for the experience: Joules
Full disclosure before anything else: Joules is our app. So take this as our opinion, not a neutral verdict. What we built it to fix is the reason most people quit tracking, which is that logging takes too long. You photograph the plate, the AI reads it, and you confirm or correct the estimate in about a second. Then it shows one daily health score that explains itself, macro rings, an intermittent fasting timer, habit streaks, and Apple Health and Google Fit sync, on a calm screen with no ads. If your hard requirement is a tracker that never charges you, be honest with yourself and lean on Cronometer or FatSecret below; if it is a tracker you will actually keep opening, start with the download page. Either way, the free calculators here need no signup.
The six free tiers, compared
| App | Free barcode | Free macros | Best free for |
|---|---|---|---|
| Cronometer | Yes | Yes, plus micronutrients | Accuracy and nutrient depth |
| FatSecret | Yes | Yes | Most complete free workflow |
| Lose It! | Premium | Yes | Simple, beginner-friendly logging |
| YAZIO | Yes | No, calories only | A free fasting timer |
| Lifesum | Premium | Premium | Design, if you upgrade |
| MyFitnessPal | Premium since 2022 | Yes, with ads | The largest food database |
Best free overall: Cronometer
What is free: nearly everything that matters. Unlimited logging, more than 80 nutrients per food from verified data, and barcode scanning, none of it behind a paywall. This is the rare free tier that a serious user can live on for years.
The catch: the interface is dense and the fasting timer is a Gold feature. You trade a bit of friendliness for the best free data anywhere. Our Cronometer review goes deeper.
Most complete free workflow: FatSecret
What is free: barcode scanning, macro tracking, a large database, and a recipe builder, all without paying. It is the app to recommend when someone wants the full logging experience at zero cost and does not need deep nutrient data.
The catch: micronutrient depth is basic, and the interface is more functional than lovely. For everyday calorie and macro logging, though, little is missing.
Simplest free start: Lose It!
What is free: food logging and basic macros, wrapped in the friendliest first-run in the category. Streaks and a clean layout make it easy to stick with in week one.
The catch: Snap It photo logging, barcode scanning, and the fasting timer are Premium at $39.99 a year. The free tier is a good on-ramp, not a destination. More in our Lose It! review.
Free fasting timer: YAZIO
What is free: calorie logging, barcode scanning, and one basic fasting timer, which is genuinely handy if you want fasting and calories in one place.
The catch: and it is a real one, the free tier shows total calories but not your protein, carb, and fat split. Macros mean PRO. See our YAZIO review.
Prettiest, if you pay: Lifesum
What is free: basic calorie logging inside the best-designed app here. The free tier is enough to see whether you like the interface.
The catch: macros, diet plans, and Snap AI logging are all Premium, so the free version is thin. Lovely, but gated. Details in our Lifesum review.
Biggest database: MyFitnessPal
What is free: food logging, macros, and the largest database in the category, more than 20 million claimed entries, so obscure foods usually show up.
The catch: ads, and no barcode scanning, which moved to Premium in October 2022. Free MyFitnessPal now means typing rather than scanning.
What about MacroFactor?
One app people expect to see here does not qualify: MacroFactor has no free tier at all, only a 7-day trial, and the company has said it will stay that way. It is an excellent paid tracker with the best adaptive algorithm around, and our MacroFactor reviewcovers it, but a "best free" list is the wrong place to recommend it.
