Making Music Adapt to Your Sleep in Real Time - iPhone + Apple Watch
An app that plays music whilst you’re falling asleep and continuously adapts it to your state throughout the night. Connect Spotify or Apple Music, put on your Apple Watch, and the app will start tracking your heart rate and movements. As soon as you fall asleep, it switches to ‘sleep companion’ mode: it tracks your sleep stages and selects the next track based on your current state. We joined the team that was already working on this product to develop new features and fix critical bugs.
