iPhone
Turn your phone into a magic instrument. Flash through your own screenshots full-screen — advanced by a tap, a shake, or a hand the camera sees.
AC Matrix turns your phone into a magic instrument. Everything an audience sees looks like an ordinary phone doing ordinary things. Everything you do to control it is invisible.
SLIDE EFFECTS
Flash through your own screenshots and clips, full-screen. Because the media is yours, the effect can be anything a phone screen can show — a home screen where the icons gather into one corner, a photo that changes when you turn the phone around, a lock screen that shouldn't exist yet.
• Cut instantly, or cross-dissolve over a length you choose
• Hold a slide for a set delay before it changes
• Let a slide advance itself, so a beat lands on time and not a moment late
• Name your slides so a long routine stays readable while you build it
TRIGGER IT HOWEVER YOU LIKE
Every slide chooses its own way in: a tap anywhere on the screen, a shake of the phone, or a hand gesture seen by the camera. Mix them inside one routine — tap, tap, shake, pinch — so no single tell repeats.
AI CLEANUP, ON DEVICE
Box out a clock, a notification, a status bar, anything that gives the game away. An inpainting model rebuilds the area from its surroundings, on your phone, and stores the cleaned copy alongside the original. One toggle switches between them. Works on stills and on video, either as a single patch or frame by frame.
Cleanup runs in the background with a Live Activity, so you can watch a long job finish from the Lock Screen instead of holding the app open.
BUILT FOR PERFORMING
• Two-finger swipe down to leave — there is no visible quit button, and that is the point
• Swipe right to step back a slide if you need to
• The screen stays awake and the status bar stays hidden
• Open the app straight into a performance, so nothing is ever seen but the effect
LEARN IT BY WATCHING IT
Every setting that describes a behaviour over time is shown as a small looping animation, not a paragraph. A "?" next to any control opens the tutorial already scrolled to the right topic. There is a filmed clip of one routine being performed, start to finish, if you would rather just watch one first.
PRIVATE BY CONSTRUCTION
AC Matrix has no network code functionality. Nothing is uploaded, nothing is analysed, no account is required. Camera frames are read for hand detection and discarded — never recorded, never saved, never sent. The AI cleanup model runs entirely on your device.
Requires iOS 17 or later. Camera gesture triggers need a physical iPhone.
