Phone apps
What a Mistflow phone app is, what ships today on Android and iPhone, and what you need for each step.
Mistflow turns a description into a real Expo / React Native phone app. You can build it, preview it on your own phone, hand it to testers, and keep changing it, all from a browser.
The path
describe → shape the screens → make it real → build + verify
→ preview on a phone → share an Android build → keep changing itEach stage has its own page:
Describing your app
The one input that most changes what you get back.
Shaping the prototype
Fix the screens before anything is built.
Make it real
What happens between pressing the button and getting an app.
Changing a live app
Edits, Keep or Discard, and what happens to your data.
What you get today
- A real Expo / React Native app, not a web page in an app shell
- A browser-based builder for creating and changing it
- A preview that opens in Expo Go on iPhone or Android
- An installable Android build you can share with a link or QR code
- An owner console on the web when your app has someone running it
- Sign-in, a database, file uploads, and AI features when the app needs them

Do not buy an Apple Developer membership for Mistflow yet
iPhone previews work today. Signed iPhone builds, TestFlight delivery, and App Store submission are not finished. If you already have an Apple account, previews work fine in the meantime. See iPhone and the App Store.
What you need
| Goal | What it takes |
|---|---|
| Create the app | A browser |
| Preview it on a phone | Expo Go, free |
| Install an Android build | An Android phone that allows installs from a browser |
| Publish to a store | A developer account with Apple or Google, plus a store-ready build |
Apple and Google run their own developer accounts, fees, identity checks, and reviews. Those apply to every app builder, Mistflow included.
What is not in this version
Some things are deliberately out of scope for now, with a workable fallback in each case:
| Not yet | Use instead |
|---|---|
| In-app subscriptions and digital purchases | Sell physical goods or services through hosted checkout, or charge on the web |
| Real-time multiplayer | Turn-based play over ordinary requests |
| AR and 3D | 2D games and canvas animation |
| Health data (HealthKit, Google Fit) | Manual entry |
| Background work beyond audio | Foreground-only |
See What your app can do for the full list, including what works today.
Costs
Previewing is free. Building and Android release usage come out of your plan. If you choose to publish to a store, the developer fees are paid directly to Apple or Google.
