Flutter: Heartbeat Sync App

Feel their heartbeat across any distance. Flutter lets couples share real-time heartbeats through Apple Watch, turning every beat into a reminder they’re with you.

Flutter lets you feel a heartbeat directly on your wrist through Apple Watch.

Designed for calm, focused awareness, Flutter turns heartbeat into a live haptic experience you can physically feel in real time. During a session, Flutter reads heart rate, displays BPM clearly, and translates each beat into a precise pulse on your wrist. Different haptic styles let you choose the sensation that feels most comfortable or meaningful.

Flutter includes Solo Sync for personal heartbeat awareness and Partner Sync for sharing live heartbeats with someone you care about. Couples, friends, and family can connect through invite-based sessions and experience real-time heartbeats together, creating a simple and intimate way to stay connected across any distance.

Sessions are easy to start and stop, with a minimal interface designed to stay out of the way and keep attention on rhythm, presence, and connection.

Flutter is a quiet, modern way to feel rhythm, presence, and connection.
