Looking for a Strong alternative?

Only what you turn on

Heart starts simple: a workout, its sets, and a timer. Most of the rest is a switch. RPE, the muscle map and the lock-screen workout are off until you want them, and the social features on the roadmap will work the same way. Two people can use Heart very differently, and both are using it right.

Your data works the same way. You don't need an account to log, everything can be exported at any time, and what Heart reads from your health app stays on your phone. The full list of what it does is on the features page.

Bringing your Strong or Hevy history

Your past workouts can come with you, so your charts and records start where you left off.

1. 1

   In Strong, open Profile → Settings → Export Strong Data. In Hevy, open Profile → Settings → Export & Import Data → Export Workouts, or export from hevy.com. Either app emails you a CSV file. Save it somewhere your phone can reach.

2. 2

   In Heart, sign in with Apple, Google or email. The import is saved to your account, so this is the one step that needs one. Anything you've already logged in Heart comes with you.

3. 3

   Open Settings → Your data → Import workout history, say which app the file is from and pick it. Heart shows how many workouts and sets are ready, and lists any exercises it doesn't recognise so you can choose which to bring over as your own.

Warm-up, drop and failure sets, RPE and exercise and workout notes come across with the numbers, and from Strong each exercise's rest timer too. A Hevy export works in any of Hevy's languages. Supersets don't carry over from either. Importing the same file again is safe: workouts already in Heart are skipped, never duplicated, so you can import again later if you keep using both for a while.

Also worth a look

Heart won't be the right fit for everyone, and that's fine. A few others people often mention:
