Flow

Turn motion, face, body, and sensor data into real-time OSC streams for creative tools, devices, and interactive apps.

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 interface inspired by tools like 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, generators like signal, noise, counter, timer, clock, and array sequencer, plus API request nodes with JSON extraction.
• Processing: Math operations, trigonometry, normalize, quantize, smooth 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 nodes that broadcast to sequential IP addresses with per-device value offsets for LED installations, coordinated displays, and multi-device performances.

REAL-TIME LIVE DATA

Monitor every node in real time. Source nodes show output data, processing nodes show both input and processed output, and destination nodes show 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 Flow sends to each device with optional per-device value offsets. Create wave effects, staggered animations, or 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 using dot-notation key paths. Auto-fetch on intervals or trigger manually.

30+ READY-MADE TEMPLATES

Start instantly 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

Live camera feed appears automatically on the canvas when running vision pipelines, with pose tracking, hand detection, or face landmarks overlaid in real time.

SAVE AND REUSE

Save workflows and destination presets. Quickly switch between network configurations. Load saved workflows from the template picker.

BUILT FOR CREATIVE TECHNOLOGISTS

Flow is designed for artists, VJs, installation designers, creative coders, and anyone who needs to get sensor data from iOS to other software or hardware. Works with TouchDesigner, Max/MSP, Processing, openFrameworks, Unity, Unreal Engine, Resolume, and any OSC, UDP, or TCP-compatible tool.
