Mobile App
The Homecast mobile app lets you control your HomeKit devices from your phone, anywhere.
Platforms
- iOS / macOS: Built with Mac Catalyst from the
app-ios-macosproject. Only the macOS build acts as a HomeKit relay; the iOS version is a client-only viewer that connects to a Mac relay. - Android / Windows / Linux: Built with Tauri from the
app-android-windows-linuxproject. Wraps the web dashboard in a native shell.

What you get
- Homes tab — browse homes and rooms, control accessories with the same widgets as the web dashboard
- Collections tab — view and control your custom accessory groups
- Settings tab — account info and appearance preferences
Differences from web
The mobile app covers the core experience — browsing and controlling devices. Some features are web-only:
| Feature | Mobile | Web |
|---|---|---|
| Browse and control devices | Yes | Yes |
| View collections | Yes | Yes |
| Create/edit collections | No | Yes |
| Drag-and-drop layout | No | Yes |
| Background images | No | Yes |
| Room groups | No | Yes |
Create and edit collections on the web, then use them from mobile. See Collections for more.
Mobile screenshots
Screenshots for the mobile app will be added after the iOS and Android apps launch.
