Patchd - Audio Visual Camera

Patchd is a collection of 20 audiovisual mini-apps that transform your camera feed and live data into interactive art and sound. Each app patches together computer vision, audio synthesis, and creative visuals into a unique experience.

No subscriptions. No ads. No data collection. Pay once, own everything.

VISION APPS
• Face Patch — Detects faces and wraps them in retro-styled frames (Win98, VHS, terminal, polaroid, and more) while sequencing beats to your expressions
• Text Patch — Reads text through your camera and turns live Hacker News headlines into rhythmic visual collages
• Pet Patch — Detects cats and dogs, draws skeleton overlays on their poses, and triggers sounds from their paw movements
• Face Puppet — Tracks 52 facial blend shapes with ARKit and maps your expressions to a multi-pattern sequencer

SOUND APPS
• Body Synth — Full-body pose detection drives a 5-pattern sequencer. Raise your arms, move your head, spread your legs — each body region activates its own instrument
• Hand Theremin — Pinch your fingers in the air to play a theremin. Distance controls pitch, hand position controls volume, with 10 selectable scales
• Object Orchestra — Point your camera at everyday objects. Each recognized object triggers its own sequencer pattern synced to a master clock
• Data Synth — A camera-free data-driven sequencer. A generated Bitcoin chart, live Hacker News stories, simulated weather, real-time clock, and random color palettes drive 8 independent sequencer patterns

VISUAL APPS
• ASCII Camera — Converts your camera feed into real-time ASCII art with adjustable character density
• Emoji Camera — Replaces every pixel region with color-matched emoji in real time
• Motion Trail — Moving objects leave ghostly trailing echoes while static areas stay sharp
• Slit Scan — Captures vertical slices of your camera over time, creating surreal time-stretched imagery

PHOTO FX
• Emoji Mosaic — Rebuilds your photo entirely out of color-matched emoji
• Pixel Sort — Sorts pixel rows by brightness, hue, or saturation for a signature glitch-art look
• Channel Shift — Offsets RGB color channels to create chromatic aberration effects
• Dither — Applies Floyd-Steinberg, Bayer, and other dithering algorithms to your photos
• Data Mosh — Simulates digital video corruption with block shuffling and channel swaps
• Fractal Mirror — Kaleidoscopic reflections that tile your photo into fractal symmetry
• Posterize — Reduces color depth for bold, graphic poster-style images
• Voronoi Shatter — Breaks your photo into geometric Voronoi cells with adjustable density

AUDIO ENGINE
All sound apps share a built-in synthesizer with 10 instruments (kick, snare, hi-hat, acid bass, tom, cowbell, and more), adjustable BPM, musical scale/key selection, reverb, and 16-step beat sequencing.

PRIVACY
Everything runs on-device. Your camera feed is never recorded, stored, or transmitted. No analytics, no tracking, no accounts. The only network request is fetching public Hacker News headlines for Text Patch and Data Synth.

Requires iOS 17.0 or later. Camera access required for all apps except Data Synth. Show More
