## What is aPix Builder?

aPix Builder — a mobile AI image & video studio that runs ComfyUI workflows on your own server or RunningHub in the cloud.

KEY FEATURES
• Connect to your own ComfyUI server (LAN or remote) or RunningHub Workflow/App via API key
• RunningHub AI App library: featured apps right on Home, browse by category, search, sort, and one-tap import
• Know the cost before you run: average run time, success rate, estimated coins; warnings for Plus GPU apps, Lite tier, and third-party model fees ($)
• Video & audio support: add video/audio inputs to apps; play and scrub video results right inside the app
• Import YAML templates — the input UI is generated to match your workflow exactly
• Shoot with the camera or pick multiple photos at once, each running as its own job (batch)
• Draw masks/inpaint directly on images with touch gestures
• Smart queue: tap Run repeatedly without cancelling previous jobs; ComfyUI and RunningHub run in parallel
• Multi-account: multiple ComfyUI servers + multiple RunningHub API keys with automatic failover when out of credits
• iCloud sync across devices (iPhone/iPad), toggle right from the quick settings popup
• Full gallery: favorites, multi-select, and one-tap reuse of a previous image's parameters
• Notifications when a job finishes, Live Activity progress on the Lock Screen
• Share images from other apps straight into the Builder, Home Screen widget, quick runs via Siri/Shortcuts
• Prompt history and library for fast reuse

The app collects NO analytics, shows no ads, and requires no account. Images and prompts are sent only to the server you configure or to RunningHub when you tap Run.

Requirements: your own ComfyUI server, or a RunningHub account (runninghub.ai) for an API key.
