This is an Android app for practising L and R sounds. It includes three separate exercises for listening, spelling and meaning, and each exercise has three levels to unlock and master.
It was a good opportunity to make use of an Sqlite database and audio playback. I did this mainly with vanilla Android, but I did make use of some convenience libraries like Calligraphy.
In the future I'd like to improve the quality of the audio files, add more levels and improve the tablet layout.
I'm a developer living in Tokyo with an interest in Android and Ruby on Rails.
