MAKE THE ROOM MOVE WITH THE MUSIC RhythMic turns nearby sound into a full-screen light show. Pick a color, animated pattern, or occasion theme, then watch every beat reshape the screen in real time. ADAPTIVE SOUND ENGINE RhythMic listens through your microphone and continuously adapts to the room. Recalibrate at any time, adjust sensitivity manually, or let Adaptive Mic Sensitivity keep the response balanced as the music changes. BASS, VOCALS, AND TREBLE Real-time frequency analysis separates low, mid, and high energy. Bass can drive powerful pulses, vocals can animate the center of the scene, and treble can add detail and sparkle. You can also tune Bass Response in Settings. 50 MUSIC-REACTIVE VISUALS Explore solid and dual colors, flowing gradients, glowing ripples, particles, waveforms, equalizer shapes, tri-band visuals, and celebration scenes for birthdays, weddings, graduation, New Year, Ramadan, Eid, and more. LIVE PERFORMANCE Build a scene timeline, choose manual or timed transitions, set each scene's intensity, reorder the running show, and control the result from one dedicated performance workspace. SYNC THE ROOM Host a secure multi-phone party over local Wi-Fi so nearby iPhones follow the same colors. Extend the show to Apple Watch, the flashlight strobe, Live Activities, and a connected external display when supported. CREATOR RECORDER Record the screen alone or combine it with the front camera, back camera, or both cameras at once on supported devices. Choose microphone audio, trim the result, frame it for 9:16, 1:1, or 16:9, and export a ready-to-share video.
