Pulse: Music Player & Auto DJ

Pulse plays the music already on your phone, and mixes it like a DJ.

DJ KAIROS
Turn on DJ Kairos and it picks the next song and mixes it in. It listens to the tempo, key and energy of your songs, so one song flows into the next. Choose a smooth blend, or a beat match that locks both songs to the same beat. Kairos tells you why it picked each song.

MIXES THAT SOUND LIVE
- Vocal swap: the next song sings over the last beat, then its own beat drops in
- Beat only in mixes, so two voices never clash
- Automatic rewinds and beat repeats on high energy songs
- Bass boost, beat only and echo while the DJ plays

YOU SHAPE THE SET
Pick when the next song comes in: after 30 seconds, 1, 2, 3 or 5 minutes, or at the end of the song. Build up or cool down the energy, or give the set a shape for 30 minutes, 1 hour or 2 hours.

YOUR PLAYLISTS, YOUR RULES
Start the DJ from a playlist or from your Favourites, and it only plays songs from that list.

EVENT DJ
Planning a party, a workout, a chill night or a road trip? Pick the event and its length, and the DJ builds the whole set. Save your events and open them again later.

SESSION HISTORY
See every session you have played, and replay the ones you loved.
