WaveRhythm – Music & Motion Reactive Color Light Turn your iPhone into a living color light that reacts to music beats and your hand waving. Whether you’re at a concert, dancing in your living room, or creating a cozy vibe, WaveRhythm fills your screen with smooth, rhythm-driven hues. Main Features: Music Reactive Mode – Detects ambient sound through the microphone. Watch screen colors pulse and change with every beat, chord, or chorus. Wave Motion Mode – Just swing your phone rhythmically (like a light stick) and the color transforms. Uses the motion sensor, no camera needed. 9 Preset Scenes – Natural, Warm, Cool, Soft, Girly, Smooth, Snowflake, Purple, Tech Blue – each with tuned brightness, saturation, and hue. Multiple Color Change Styles – Random Hue, Random Scene, Ordered Hue, Ordered Scene, Reverse Ordered – you control the flow of the light show. Full Manual Control – Adjust hue, saturation, and brightness sliders anytime to create your perfect color. Fine-Tuned Sensitivity – Customize threshold, cooldown time, and animation speed for both music and motion modes. Haptic feedback on each trigger. Clean & Minimal UI – Tap to hide controls for a full-screen immersive experience. Swipe horizontally to cycle scenes, vertically to adjust device brightness. Perfect for live concerts, music listening, parties, vlogging fill light, baby night lamp, or just relaxing ambient mood lighting. Note: Music reactive mode requires microphone permission (audio is only used locally to detect sound level, never recorded or stored). Wave motion mode uses device motion data. Download WaveRhythm and feel the flow of light in your hands!
