Tempo is a music statistics application designed specifically for Android devices that tracks listening activity across over 20 different music platforms and services. It functions as a comprehensive music tracker that unifies listening data into a single timeline, providing users with detailed insights about their music consumption patterns.

The application works with 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 offers real-time "Wrapped-style" insights that can be viewed for any time range including today, week, month, or all-time periods. The app generates cinematic story cards specifically designed for sharing music listening experiences.

Tempo operates by leveraging Android's native NotificationListenerService to track music playback across supported applications. This approach ensures minimal battery consumption while maintaining full functionality. The app processes all data locally on the user's device without requiring cloud uploads or backend servers.

The primary benefit of Tempo is its privacy-first approach where all listening history remains exclusively on the user's device with zero data leakage. Users gain access to deep statistics including discovery dates, fan badges, engagement scores, moods, and listening personalities without compromising their personal data. Optional Spotify integration is available solely for enhanced metadata retrieval such as high-resolution album art and genre information.

Tempo targets Android users who want detailed music statistics without sacrificing privacy. It's particularly useful for music enthusiasts who use multiple streaming services and want unified insights. The app is open source and currently offers data export/import functionality with Google Drive backup capabilities under development for seamless device transitions.
