A gym app with no account and no ads

In short

Without the optional features Butties and Strava, workouts, weights, nutrition and steps stay on your iPhone. GymButt has no ads and no analytics. You only need an account for Butties, the groups with friends.

What stays on your iPhone

Workouts, weights, nutrition, history and records are stored locally on your iPhone. GymButt needs no account or email address for that. The app reads steps from Apple Health, but only if you allow it.

What GymButt doesn't have

• No ads, in any version.
• No analytics and no tracking of app usage.
• No public profiles and no leaderboard.

What Butties stores

Only if you use Butties and sign in with Apple, GymButt stores your nickname, your Butt, level and streak, your daily status and your weekly challenge number at Google Firebase in Zurich. The members of your group can see these. If you send a Buddy a workout template, it stays on the server for 30 days at most, until it's accepted or declined. You delete your Butties account yourself in the app under “GymButties”.

What Strava gets

If you connect Strava, a workout only goes to Strava when you send it: name, start time, duration and exercises with sets, reps and weights. Your Strava sign-in is kept in your iPhone's Keychain.
