Release 26.37 — Updated September 8, 2026

Code on the Go

Code on the Go (CoGo) is a mobile-first, offline-capable IDE for building full Kotlin and Java apps on Android phones and tablets without any additional hardware 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. 

Breaking change next week: In the September 15 release (26.38), we will upgrade the core development stack for 64-bit devices. This will be a breaking change.

There was a time when developing a complete Android app without a PC felt like an impossible dream. But your app, "Code on the Go," turned that dream into reality for me.

[CoGo] has been incredibly helpful to me, especially as I do not own a laptop or a PC powerful enough to run Android Studio comfortably.

Building a full Jetpack Compose integration directly on a mobile device felt just like using Android Studio on a PC...It's a literal game changer for on-the-go development.

I’ve been using Code on the Go mainly for learning and building small Android projects. It’s been super helpful for practicing Java and understanding real app development directly on mobile.

[CoGo] is the most powerful IDE on Android I've ever seen.

FAQ goes here

This is a paragraph about something cool, but it’s super theoretical and there isn’t any kind of meaningful illustration for it. So I need a setup for that kind of content as a feature, too.
