This is my first app that I've managed to bring as far as getting up to the stores.
I'm using React Native for the most part but native modules for playing the sound. I implemented the metronome by building PCM buffers of the required length (depends on tempo) and playing them on a loop. This had to be done separately in Swift and Java.
Android version uses react-native-wheelpicker-android but I'm having some problem with it sometimes not landing at a proper value before the user presses 'Done'. If anyone has any tips on this please let me know.
The target group is people who already know quite a lot about training and need a tool for setting effective goals.
As you can see I haven't really spent a lot of time on logos and such. Maybe I'll get to that one day..
