GruKit

Flow turns your iPhone and iPad into a powerful sensor hub. Build visual data pipelines by connecting nodes on a canvas and stream camera, motion, and AR data to any device over OSC, UDP, or TCP. Visual Node Editor Drag, connect, and configure nodes on an interactive canvas. No coding required. Build complex sensor routing in minutes with an intuitive drag-and-connect workflow inspired by TouchDesigner and Max/MSP. 50+ Nodes in 3 Categories Sources: Camera and Vision data including body pose, hand tracking, face landmarks, device sensors such as accelerometer, gyroscope, magnetometer, barometer, and ARKit streams, plus generators like signal, noise, counter, timer, clock, array sequencer, and API request nodes with JSON extraction. Processing: Math operations, trigonometry, normalize, quantize, smoothing filters, map range, waveform modulation, oscillators, logic gates, comparators, thresholds, triggers, delay, sample and hold, looper, vector math, string formatting, and JSON building. Destinations: TCP client and server, UDP sender, OSC sender, plus multi-device broadcast nodes that target sequential IP addresses with per-device value offsets for installations, coordinated displays, and multi-device performances. Real-Time Live Data Monitor every node in real time. Source nodes show live output, processing nodes show both input and processed output, and destination nodes show exactly what they receive. Human-readable formatting covers JSON pretty-printing, pose joint details with confidence bars, hex blob previews, matrix grids, and sparkline history charts. Multi-Device Orchestration Set a base IP and device count and let Flow send to each device with optional per-device value offsets. Build wave effects, staggered animations, and synchronized installations across OSC, UDP, or TCP. API Integration Fetch data from any REST API with configurable HTTP method, headers, and request body. Extract values from JSON responses with dot-notation key paths, auto-fetch on intervals, or trigger requests manually. 30+ Ready-Made Templates Start with pre-built workflows for hand tracking, body pose, face landmarks, accelerometer streaming, ARKit world tracking, noise generation, signal processing chains, multi-device broadcasting, and more. Camera Preview When a vision pipeline runs, the live camera feed appears directly on the canvas with pose tracking, hand detection, or face landmark overlays in real time. Save and Reuse Save workflows and destination presets, switch between network configurations quickly, and load saved setups directly from the template picker. Built for Creative Technologists Flow is designed for artists, VJs, installation designers, creative coders, and anyone who needs to move sensor data from iOS into TouchDesigner, Max/MSP, Processing, openFrameworks, Unity, Unreal Engine, Resolume, or any OSC, UDP, or TCP-compatible tool. Technical Highlights iOS 17+ built with SwiftUI and Swift Concurrency 60fps pipeline engine with actor-based architecture Network.framework for low-latency TCP and UDP transport Full OSC 1.0 protocol support Vision framework for real-time pose estimation CoreMotion support for device sensors ARKit for world and face tracking

Patchd is a collection of 20 audiovisual mini-apps that transform your camera feed and live data into interactive art and sound. Each app combines computer vision, audio synthesis, and creative visuals into a distinct experience. No subscriptions. No ads. No data collection. Pay once and own everything. Vision Apps Face Patch: Detects faces, wraps them in retro-styled frames like Win98, VHS, terminal, and polaroid treatments, and sequences 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 ARKit facial blend shapes and maps your expressions to a multi-pattern sequencer. Sound Apps Body Synth: Full-body pose detection drives a 5-pattern sequencer. Arms, head, and legs each activate their own instruments. Hand Theremin: Pinch in the air to play a theremin where finger distance controls pitch and hand position controls volume across 10 selectable scales. Object Orchestra: Point your camera at everyday objects and let each recognized item trigger its own sequencer pattern synced to a master clock. Data Synth: A camera-free sequencer driven by generated Bitcoin charts, live Hacker News stories, simulated weather, real-time clock data, and random color palettes across 8 independent patterns. Visual Apps ASCII Camera: Converts the live camera feed into adjustable real-time ASCII art. Emoji Camera: Replaces pixel regions with color-matched emoji in real time. Motion Trail: Moving objects leave ghostly trailing echoes while static regions stay sharp. Slit Scan: Captures vertical slices of the camera feed over time to create surreal time-stretched imagery. Photo FX Emoji Mosaic: Rebuilds photos entirely out of color-matched emoji. Pixel Sort: Sorts rows by brightness, hue, or saturation for classic glitch-art textures. Channel Shift: Offsets RGB channels for chromatic aberration effects. Dither: Applies Floyd-Steinberg, Bayer, and other dithering algorithms. Data Mosh: Simulates digital video corruption with block shuffling and channel swaps. Fractal Mirror: Tiles a photo into kaleidoscopic fractal symmetry. Posterize: Reduces color depth for bold poster-style graphics. Voronoi Shatter: Breaks photos into geometric Voronoi cells with adjustable density. Audio Engine All sound apps share a built-in synthesizer with 10 instruments including kick, snare, hi-hat, acid bass, tom, and cowbell, plus adjustable BPM, musical scale and key selection, reverb, and 16-step beat sequencing. Privacy Everything runs on-device. Your camera feed is never recorded, stored, or transmitted. There are no analytics, no tracking, and no accounts. The only network request is fetching public Hacker News headlines for Text Patch and Data Synth. Requirements Requires iOS 17.0 or later. Camera access is required for every app except Data Synth.

Creative utility toolkit for mobile producers. Includes quick MIDI helpers, sample cleanup, and session assistant tools.
