Microtonal tuning app for Android

Hi all,
I just recently released my microtonal tuning app for Android. It was built using a combination of JUCE as a dynamic library, for the audio and custom GUI stuff, and Kotlin for the rest.

You can check it out on Google Play: https://play.google.com/store/apps/details?id=com.nodeaudio.entonaltuner

There are lots of features in the pipeline. Feedback welcome!
