Hong Kong Radio Schedule

https://radio.benleungcreative.com/
Hong Kong Radio Schedule is my self-initiated project. I started this project when I was studying at the university and used Android as my first entry point to mobile app development. Also, I've improved the project from time to time, working on the third-party managed back end or self-hosted server. This app has been downloaded more than 70 thousand times in total for both iOS and Android.
