Tempo tracks listening across 20+ Android music apps including Spotify, YouTube Music, Apple Music, Amazon Music, Deezer, Tidal, Pandora, SoundCloud, JioSaavn, Gaana, Wynk, Poweramp, Musicolet, BlackPlayer, Resso, Audiomack, Trebel, Qobuz, VLC, and Samsung Music. It unifies your listening history into one timeline and provides "Wrapped-style" insights in real-time for any range—today, week, month, or all time.

Tempo offers deep statistics including discovery dates, fan badges, engagement scores, moods, and listening personalities. The app creates cinematic story cards built for sharing and provides rich metadata with high-res album art, genres, and heavy rotation insights from MusicBrainz and Spotify API (optional). All data stays local with no backend, and includes export/import functionality with Google Drive backup.

The app works by leveraging Android's native NotificationListenerService to track music playback across supported applications. It processes everything locally on your device, ensuring zero data leakage and full functionality without an internet connection.

Tempo provides privacy-focused music insights without requiring users to trade privacy for functionality. It works without any account needed and offers offline-first operation with minimal battery consumption.

Tempo is designed for Android users who want detailed music statistics while maintaining complete privacy. The app is open source and specifically caters to music listeners who use multiple streaming services and want unified tracking without cloud dependency.
