Show HN: Android guitar looper app for creating seamless practice loops

I’m a developer and hobby guitarist, and I built a small Android app to help with practicing.

I always wanted to make a cross-platform native app in C (C99), and this is my attempt. I started on macOS and then moved to Android. The hardest parts so far have been JNI integration and handling permissions. The GUI is custom and rendered with OpenGL ES.

The app records seamless, bar-perfect loops with a precount click, so you can strum chord changes and improvise over them.

Happy to answer questions or get feedback.
