Download Code on the Go
Code on the Go (CoGo™) is a mobile-first, offline-capable IDE for building full Kotlin and Java Android apps on Android phones and tablets, without needing a computer or internet access. With CoGo, you can:
- Write, edit, debug, and build Android projects on your phone.
- Extend the app’s capabilities with plugins (and build the plugins you need for your own unique projects).
- Try our Sketch to UI™ feature! Turn a photo of a hand-drawn UI sketch into Android XML.
- And much more!
CoGo was updated on June 23, 2026. Click here to read the release notes.

Installation and setup
Use the buttons above to download the app. Please follow the prompts during setup.
Note: CoGo requires the Android permission to display over other apps. Some phones, including Google Pixels, may restrict the permission so that you can’t enable it during installation. If you can’t enable a permission, follow these steps to resolve the problem:
- Open the device’s Settings.
- Navigate to Apps > Code on the Go, and tap the Code on the Go icon to display the app information page. (Your device may have a different name or path.)
- Tap the three-dot menu typically displayed at the upper right, and select Allow restricted settings.
- Verify your identity.
- When the process is complete, return to the Code on the Go setup page. You can now add the permission.
