iPhone
You've always heard music. Now feel it in real time. Share the physical vibe with friends via Live Haptic Share and swipe through your daily discovery feed.
Your music. Now tactile.
UACQ turns your iPhone into a haptic music player — one that doesn't just pulse on the beat, but responds to the full texture and emotion of every track.
--- NEW FEATURES IN THIS BUILD ---
1. LIVE HAPTIC SHARE
Experience music physically, together. Using local peer-to-peer technology, UACQM2V4 lets you share your haptic playback with up to 4 friends nearby with millisecond-level synchronization. Feel the same bass drops, synths, and emotional changes simultaneously.
2. TIME CAPSULE (DAILY DISCOVERY FEED)
Swipe through your personalized daily music recommendations in a gorgeous, artwork-reactive gradient feed. Turn on Auto-Advance mode to glide through discoveries (at song end, or every 30/60 seconds), and double-tap to save your favorites with high-fidelity haptic feedback.
3. BUILT-IN AMBIENT STATION
Don't have Apple Music? No problem. Tap into the Station tab and choose from a selection of copyright-free ambient tracks. Experience the full depth of the haptic engine instantly, right out of the box.
---------------------------------
NOT JUST BEAT SYNC
Most haptic music apps work like a metronome: they detect the beat and vibrate on it. UACQM2V4 goes further. It listens the way you do — picking up on the energy of a bass drop, the tension of a rising synth, the calm of a sparse piano phrase — and translates all of it into sensation. The vibration changes not because the beat changed, but because the music did.
EMOTION, NOT JUST VOLUME
Louder doesn't always mean more intense. A quiet but tense passage should feel different from a quiet, peaceful one. UACQM2V4 tracks the emotional energy of a track in real time and adjusts haptic intensity accordingly. The result is feedback that feels musical, not mechanical.
ENTIRELY ON-DEVICE
Everything happens on your iPhone, in real time, with no cloud processing and no delay. The haptic response is synchronized to the audio — not scheduled ahead of time, not approximated from metadata.
HOW IT COMPARES
• Zero latency — haptics are driven by the live audio signal, not pre-scheduled to a beat grid.
• Any track, instantly — works on both built-in ambient tracks and everything in your Apple Music library.
• Adapts in real time — the response continuously updates as the music evolves, not locked to a fixed pattern.
• Emotion over volume — intensity follows the emotional energy of the track, not just how loud it is.
• Transparent logic — an optional overlay shows exactly what the engine detected and why, so the feedback is never a black box.
