Kyomei
Read full descriptionHide full description
When you and someone nearby are listening to the same song or artist, a quiet signal appears — a moment of connection through music. No profiles. No chatting. No noise. Just music, and the moments it creates. Features: • Detect nearby music resonance • See which song created the moment • Keep a private archive of where it happened • Runs quietly in the background Currently, Kyomei supports Apple Music and locally played audio on your device. Support for additional music players may be added in future updates. Kyomei focuses on simplicity and subtlety. It doesn’t interrupt — it reveals. Privacy-first design: • We only access your currently playing song title and artist • No audio data is collected or stored • No full listening history is accessed • Your location is only used to record your own resonance moments • We do not identify, track, or store information about other users Music is usually personal. Kyomei makes it shared — just for a moment.
