Questions.

Is marble free?

Yes. Every feature is free, with no subscription, no ads, and nothing to unlock.

Does marble work offline?

Yes. Logging, parsing, progress, and storage all run on your iPhone or iPad. There is no marble account or server to connect to.

Does marble need Apple Intelligence?

No. Where Apple Intelligence is available, marble uses it on device to structure workouts written as prose. Gym notation such as “Squat 5x5 @ 225” and Hevy or Strong CSVs are read by an on-device parser on every supported device. Either way, you review everything before it is saved.

Can I import my history from Hevy or Strong?

Yes. Bring in a Hevy or Strong CSV export through Add, then review each workout, exercise match, and set before anything is saved.

Does marble work with Apple Watch or Garmin?

Yes, through Apple Health. marble imports Apple Watch workouts and Garmin workouts that sync to Health, and can optionally send your strength sessions back to Health with an effort score. There is no separate Apple Watch app.

How do I find marble on the App Store?

Search for marble.fit, or use a Download button on this page. The App Store listing is called marble.fit; the app itself is marble. It needs iOS or iPadOS 26 or later.

Is marble a good alternative to Hevy or Strong?

If you want a private journal rather than a social feed or a subscription, yes. Every feature is free, there is no account, and your Hevy or Strong CSV imports on your iPhone. There is no Android app, web app or cloud sync. See switching from Hevy and switching from Strong.

Does marble sell my data or show ads?

No. The app has no ads, marble account, marble server, or third-party tracking, and your data is never sold. Its App Store privacy label reads Data Not Collected, and the source code is public. This website uses anonymous, aggregated Vercel Analytics.
