We have just made the Aeolian Meditation Control app open source. Feel free to grab it, edit it, bastardize it, learn from it, rip code blocks from it, laugh at it, eat it or whatever you want

If you are new this, all it takes is Android Studio which is free, and then just download the whole project and open it there. You will have to learn a bit on how to run the build and/or set up an emulator or your android device with Android Studio, but all the info is well documented online.
If you already know your way around then just build it and it should run ( we can only hope
