Your own apps, built for exactly what you need
A planner for the road trip you’re taking next month. A tracker for your six-month fitness goal. Tell Claude, ChatGPT or Gemini what you need — CanvasRunner turns it into a real app on your phone. Private, offline, made for one person: you.
Works with Claude, ChatGPT and Gemini — or any app you can copy text from.
Made for you — not for a million users
App-store apps are built for everyone, so they’re full of things you don’t need. The apps you build here do one job — yours — with no sign-up walls, no ads, and no upsells.
From idea to app in seconds
No build step, no deploy, no link to open. Three moves.

CanvasRunner is a share target — send the app straight from your assistant’s app, or let CanvasRunner pick it up from the clipboard. It never auto-creates anything; you confirm each one.
Not quite right? Change it.
Open any app back up. There’s a real JavaScript console, a network log, and a storage view — the kind of thing Android won’t give you without a USB cable and desktop Chrome.
When something’s off, tap Copy fix prompt, paste it back to Claude, ChatGPT or Gemini, and get a new version. Your trip planner keeps up as the trip takes shape.
A shelf of apps only you have
Sign in with Google or email and your apps back up privately to your account, so they follow you to a new phone. Pin the ones you use to your home screen; delete everything from Settings whenever — it’s your data.
CanvasRunner does not proxy, embed, or render any third-party website. Every app it runs is authored by you.
