A rhythm and loop companion for practicing, organizing, and playing percussion patterns.
Loopsic for iOS is a practice companion built around the small decisions that make a rhythm useful: choose a pattern, set its tempo, repeat it, save it into a playlist, and return to it later. The shared SwiftUI layer and audio engine support that flow across playback, custom loops, shop access, background activity, and localization.
- Percussion and rhythm pattern browsing
- Loop playback with BPM control and repeat mode
- Custom loops and playlist management
- Saved tempo and practice-oriented playback state
- Premium rhythm packs and shop flow
- Shared views, view models, services, and models
- Background playback and Live Activity support
- Localized App Store metadata
- Google Mobile Ads and Firebase messaging/analytics integrations
