UK ENGLISH

The app uses British English spelling and conventions (colour, favourite, etc.) with support for multiple languages including US English, French, German, and Spanish.

PRIVACY FOCUSED

No account required. No data collection. All your presets are stored locally on your device. Optional iCloud sync keeps your workouts backed up across your devices.
