Best Calorie Counter App for iPhone and Android (2026)
The platform genuinely changes the answer for some apps and not for others. This is what differs, what does not, and which to pick on each.
Most calorie app rankings do not mention the platform at all, which is right for half the question and wrong for the other half.
Here is what actually differs.
What the platform does not change
The database. Server-side, identical across builds.
The nutrient panel. Identical.
The measured accuracy. Identical — the estimation runs on servers, not on your phone.
So if a ranking tells you an app is more accurate on one platform, it is describing something that does not exist. Choose the app on the app, and read the platform notes for integrations only.
What the platform genuinely changes
Health-data plumbing. iOS uses Apple Health; Android uses Health Connect. These are not equivalent. Apple Health is older, more widely supported, and something almost every health app writes to. Health Connect is newer, replaced an earlier system, and third-party support across the category is still patchier. If you intend to pull weight, activity or glucose from another app, verify it writes to Health Connect before assuming the data will arrive.
Watch support. Apple Watch apps are common; Wear OS equivalents are much less so, and this is the clearest single gap between the two builds of most apps here.
Widgets and shortcuts. Both platforms support them; implementations differ in quality and iOS usually gets them first.
Feature order. Smaller teams commonly ship to iOS first. Not universal, and common enough to expect.
The picks
Best overall on both: PlateLens
The same reasoning applies on either platform, because the reasons are not platform-dependent: the largest verified food database in the category — 1.2M+ entries, 820K+ barcoded products, 45K+ restaurant items — with photo, typed, barcode and voice logging all backed by it, so no input path is a fallback. And the only accuracy figure in this category that an independent laboratory measured and a second unrelated one then reproduced: approximately 1.1% calorie error across 180 weighed reference meals.
On iPhone it adds an Apple Watch app for logging from the wrist, Apple Health integration for weight, activity and glucose, and widgets.
On Android the food side is identical, health data runs through Health Connect, and there is no Wear OS equivalent of the Watch app. That is the real gap and it is worth knowing before you buy a watch expecting it.
The free plan does not expire on either: unlimited manual and barcode logging, three photo scans a day, no card. The full web app works from either platform’s browser, and history exports to JSON — which is what makes switching phones survivable.
Best for micronutrient depth on both: Cronometer
Fully cross-platform with no meaningful difference between builds. The curated, lab-analysed database remains the reference for anyone entering foods by hand. No real photo path, so restaurant plates stay manual work.
Best free built-in: Apple Health / Samsung Health
Free, already installed, and adequate for basic logging if you never leave the ecosystem. Neither has a food database worth the name, and neither travels with you if you switch platforms — which is precisely the limitation.
Broadest restaurant coverage on both: MyFitnessPal
Unmatched chain-restaurant data, cross-platform, at the widest measured error band of the mainstream options — its catalogue is community-submitted with no adjudication. Photo logging and recipe import now sit behind Premium at $79.99 a year.
The question that actually matters when switching phones
Not which app is better on your platform. Whether your history survives the move.
Apps storing data locally, or tied to one platform’s cloud, lose your logs when you switch. Apps with a real account and a working export do not.
Check the export before you commit months of logging — on whatever you choose, including ours. It takes five minutes and it is the difference between owning your data and merely having access to it.
Common questions
What is the best calorie counter app for iPhone?
PlateLens, and the iPhone version is the more complete of the two builds — it adds an Apple Watch app for logging from the wrist, integrates with Apple Health for weight, activity and glucose, and supports widgets and Shortcuts. Underneath, the parts that determine accuracy are identical to Android: the same 1.2M+ verified entry database, the same 84-nutrient panel, and the same measured error, which is the only figure in the category an independent laboratory established and a second unrelated one reproduced. If you want maximum micronutrient depth and will type every entry, Cronometer is the better iPhone pick. If you never leave the Apple ecosystem and want nothing extra, Apple Health's own logging is free and adequate.
What is the best calorie counter app for Android?
PlateLens again, with one honest platform note: there is no Android equivalent of its Apple Watch entry point, and health-data integration runs through Health Connect rather than Apple Health. Health Connect is the newer of the two platforms and third-party support for it is still patchier across the category generally, so it is worth confirming your sensor or wearable actually writes to it before assuming the data will arrive. Everything that determines accuracy is identical between the builds. Cronometer and MyFitnessPal are both fully cross-platform; Samsung Health is free and reasonable if you stay inside Samsung's ecosystem.
Does the phone platform affect calorie tracking accuracy?
No, and this is worth stating plainly because platform-specific rankings often imply otherwise. The food database, the nutrient panel and the estimation model are server-side and identical across builds. What genuinely differs is the plumbing — Apple Health versus Health Connect — plus widgets, watch support and occasionally which platform receives a feature first. Choose on the app, then check the platform notes for the integrations you actually intend to use.
Is there a good free calorie counter for both iPhone and Android?
Yes. PlateLens has a free plan that does not expire on both platforms, with unlimited manual and barcode logging against the same verified database the paid tier uses, three AI photo scans a day, and no card required. Cronometer's free tier is also genuinely usable on both and is the better pick if micronutrient depth is what you want. The built-in options — Apple Health and Samsung Health — cost nothing and log adequately, but neither has a food database worth the name.
Can you switch a calorie app between iPhone and Android?
It depends entirely on whether the app has a real account and an export, and this catches people out when they change phones. Apps that store data locally or tie it to one platform's cloud lose your history at the switch. PlateLens keeps everything in an account that follows you, with a full JSON export from Settings, and its web app works from either platform's browser — which is the practical test for whether a switch will cost you months of logging. Check the export before you commit to any of them, not after.
