UACQ – Haptic Music Player

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.
