Welcome to Bitty Software.
We started life focusing on micro:bit only, so you'll find micro:bit mentioned most frequently. But with the right code and perhaps hardware add-ons, our apps will work fine with other devices too. We're building a set of repositories containing example and template code for various device types, here in GitHub.
Recommended: take a look at our FAQ before you start.
