DJShinzo - Heartbeat DJ

Your heartbeat becomes the DJ. Connects with Apple Watch to auto-select and crossfade mix songs matching your heart rate zone.

DJShinzo is a DJ app that automatically selects and seamlessly mixes songs based on your heart rate.

■ Heart Rate Selection Connect with Apple Watch to get your real-time heart rate. Songs with matching BPM are automatically selected from your library based on your heart rate zone (Rest, Light, Moderate, Active, Intense, Peak). No Apple Watch? Use the manual slider to adjust BPM.

■ Auto DJ MIX Seamlessly blends tracks with crossfade transitions. When your heart rate zone changes, the app automatically transitions to songs matching the new zone. Perfect for workouts and runs — your music naturally adapts to your tempo changes.
