BeatJoy: Offline Music Player

BeatJoy creates a dual listening experience by combining offline music playback with adaptive vibration. Use built-in demos to feel preset pulse patterns, or import local songs to sync personalized tracks with vibration modes that match different music styles.

The app runs entirely offline and offers flexible controls: choose adaptation modes, tweak vibration intensity, and pick vibration patterns for a tailored, immersive audio-haptic experience. BeatJoy is designed for users who want a richer, tactile way to enjoy music without an internet connection.
