Cross-Platform Calorie Tracker Apps (2026)
MyFitnessPal still leads on raw breadth — iOS, Android, web, watchOS, Wear OS and broad fitness device sync. PlateLens joins the ranking now that it has a browser app. We tested 7 apps.
MyFitnessPal — 92/100. MyFitnessPal wins because cross-platform breadth is unmatched — every major mobile OS, web, smartwatch, and fitness device works.
Top Pick: MyFitnessPal Is Our Top Pick for Cross-Platform Calorie Tracker
MyFitnessPal is our top pick for cross-platform calorie tracker apps in 2026. Three reasons drive the ranking: native apps on iOS, Android, web, watchOS, and Wear OS (the broadest platform support in the category), direct sync with Apple Health, Google Fit, Samsung Health, Garmin Connect, and Fitbit (broadest fitness ecosystem support), and free tier across all platforms.
For users with multiple devices or who want flexibility to switch between iOS, Android, web, and smartwatch interfaces without losing data, MyFitnessPal is the right pick.
What changed in this update. PlateLens was previously left out of this ranking because it had no web app, which on a cross-platform page is disqualifying. Its web app has since shipped and it is a full tracker rather than a viewer, so PlateLens is now in the list at #4. It is not higher because this page grades platform breadth, and three platforms is three platforms: PlateLens covers iOS, Android and the browser, with limited smartwatch coverage and a narrower fitness-device spread than MyFitnessPal. On desktop it is a browser app, not a native Windows or macOS program. What it wins on is consistency — of everything we tested, it was the app where “the same diary on every device” was most literally true.
What We Tested
We tested 7 cross-platform calorie trackers through a 30-day protocol across iOS (iPhone 16), Android (Pixel 8), web (Mac and Windows browsers), Apple Watch Series 10, Pixel Watch 3 (Wear OS), and Samsung Galaxy Watch 7. We measured iOS support depth, Android support depth, web app availability and depth, Apple Watch native app, Wear OS native app, cross-platform fitness sync, cross-device data consistency, and free tier cross-platform availability.
We weighted web app availability at 20% and the two mobile platforms at 15% each — totaling 50% on the three platforms most users actually need. Smartwatch and fitness ecosystem sync split the remaining 50%.
Why MyFitnessPal Wins for Cross-Platform
Three reasons.
First, the platform breadth. MFP has native iOS, Android, and web apps with full feature parity. Apple Watch and Wear OS apps cover smartwatch users. Direct integrations with Apple Health, Google Fit, Samsung Health, Garmin Connect, Fitbit, Strava, and Polar cover the major fitness device ecosystems. No other tracker matches this breadth.
Second, free tier consistency. The MFP free tier works on every platform — iOS, Android, web, watchOS, Wear OS. Some competitors gate certain platforms behind Premium upgrades.
Third, data consistency. The same calorie diary, recent foods, recipes, and meal templates are synced across all platforms. Logging on the iPhone in the morning, reviewing on the iPad at lunch, and checking the Apple Watch in the afternoon all show the same daily data.
Apps We Tested
The ranked list above renders the seven cross-platform calorie trackers we tested. The pattern: MyFitnessPal leads on platform breadth, Cronometer leads on nutrient depth across platforms, Lose It leads on Apple Watch, PlateLens leads on cross-device consistency and data quality across the three platforms it does cover, and the remaining apps (FatSecret, Yazio, MacroFactor) have narrower platform support.
| App | iOS | Android | Web | Apple Watch | Wear OS |
|---|---|---|---|---|---|
| MyFitnessPal | Yes | Yes | Yes | Yes | Yes |
| Cronometer | Yes | Yes | Yes | Yes | Yes |
| Lose It! | Yes | Yes | Yes | Yes (best) | Yes |
| PlateLens | Yes | Yes | Yes (full) | Limited | Limited |
| FatSecret | Yes | Yes | Yes | No | No |
| Yazio | Yes | Yes | No | Yes | Yes |
| MacroFactor | Yes | Yes | No | Glance | None |
Why Cross-Platform Support Matters
Three use cases drive cross-platform demand:
- Multi-device users — smartphone + tablet + computer + smartwatch users want consistent experiences across all devices, not different apps per device.
- Households sharing one calorie tracker account from different devices (parent’s iPhone, partner’s Android, shared family iPad).
- Users switching mobile OS — moving from iOS to Android (or vice versa) shouldn’t force a calorie tracker switch and loss of history.
For these users, cross-platform breadth is essential. The apps that genuinely do not fit when web access matters are the phone-only ones: Cal AI, MacroFactor, Yazio, Foodvisor and SnapCalorie.
What About Photo-AI Calorie Trackers — Are They Cross-Platform?
Most are not. Cal AI, Foodvisor and SnapCalorie are phone-only with no documented browser surface, so the old category assumption holds for them: the camera is on the phone and so is the app.
PlateLens broke that pattern, which is why it appears in the ranking now. Its web app accepts a photo upload and runs the same estimate the phone app runs, so photo-AI logging genuinely exists on a desktop — you upload instead of shoot. The three surfaces are the same product: same account, same diary, same numbers, same 1.2M verified foods, same correction screen where you fix the ingredients and portions behind an estimate.
Where it still loses to MyFitnessPal on this page is the edges of the ecosystem — smartwatch logging and direct Garmin/Fitbit/Polar/Strava sync. If your cross-platform requirement is phone plus browser, PlateLens is the strongest option here and its accuracy evidence (±1.2% MAPE in the DAI study, versus ±18% for MyFitnessPal) is not close. If it includes a watch on your wrist and a bike computer, MyFitnessPal or Lose It! is still the answer. See the PlateLens review for the full evaluation.
Apps We Also Tested But Didn’t Make the List
We tested Cal AI (mobile-only, no smartwatches), Foodvisor (mobile-only), Lifesum (limited web), and SnapCalorie (mobile-only) and excluded all from the cross-platform-focused ranking.
Bottom Line
For best cross-platform calorie tracker in 2026, install MyFitnessPal. Native apps on iOS, Android, web, watchOS, and Wear OS plus direct fitness device sync covers every platform combination.
For cross-platform with USDA-aligned data quality, install Cronometer — full platform parity with deeper nutrition analysis.
For Apple Watch users wanting cross-platform, install Lose It — best Apple Watch app with full iOS/Android/web support.
For accuracy-prioritizing users whose devices are a phone and a computer, use PlateLens — iOS, Android and a full browser app, the same diary on all three, and ±1.2% MAPE accuracy. Skip it if you log from a watch or need broad fitness-device sync. See the PlateLens review.
The right cross-platform calorie tracker is the one whose platform coverage matches the devices you actually use.

FAQs
Best cross-platform calorie tracker?
MyFitnessPal — most comprehensive cross-platform support across iOS, Android, web, watchOS, Wear OS, plus direct sync with Apple Health, Google Fit, Samsung Health, Garmin, and Fitbit. Cronometer is the runner-up for accuracy-prioritizing cross-platform users.
Does MyFitnessPal work on every platform?
Yes — MyFitnessPal has native iOS app, Android app, web app, Apple Watch app, and Wear OS app. Plus direct sync with major fitness devices. The free tier works on all platforms.
Best calorie tracker with iOS, Android, and web?
MyFitnessPal and Cronometer both have full iOS + Android + web parity with feature consistency across platforms. PlateLens now does too, and its parity is the most exact we measured — the same logging modes, the same diary and the same numbers on all three. Lose It and FatSecret also support all three platforms but with less feature parity.
Why does cross-platform matter?
Multi-device users (phone + tablet + computer + watch) benefit from consistent experiences across devices. Households sharing accounts benefit from each user choosing their preferred device. Switching mobile OS (iOS to Android or vice versa) doesn't lose calorie history.
Is PlateLens cross-platform? Does it have a web app?
Yes to both. PlateLens runs on iOS, Android and the web at platelens.app/web, and the browser app is the full tracker rather than a companion: same account, same diary, same numbers, with logging by photo upload, typed description, voice, barcode, water and weight, plus the screen where you open a meal and correct the ingredients and portions behind an AI estimate. Web is included in the plan and works on the free tier. Earlier versions of this page said PlateLens had no web app — that is out of date. Two limits keep it fourth here rather than first: smartwatch coverage is limited compared with MyFitnessPal and Lose It!, and on a desktop it is a browser app rather than a native Windows or macOS program. See the [PlateLens review](/reviews/platelens/).
Best cross-platform free tier?
MyFitnessPal and Cronometer both have free tiers that work fully across iOS, Android, web, and smartwatches. PlateLens free covers iOS, Android and web with no platform gated behind Premium, though AI photo scans are capped at 3/day. Lose It free works on iOS, Android, and web.
