【實用教育app】Key Signature Tool|最夯免費app-綠色工廠好玩App

This app is written for musicians to learn their key signatures. It is written from the perspective that your instrument of choice is a C instrument.

Further Improvements may include allowing the user to select their instrument of choice beforehand and providing the key signature based on the instrument selected.

Note: This is my first android application. I am publishing this as a learning experience. Thank you for your support. I hope to get better as I continue to learn.
