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 July 21, 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 the permission, follow the instructions on the screen to open the App Info page and change the settings.
