I have something that works, and is usable for someone that is determined. The next step is something that is fun, easy to use and motivating.
I'll need:
- a rock solid foundation, users should always get correct feedback about their progress
- notifications, training plans
- dunk mode: just put your hands up and it will tell you how much you have to improve if you want to dunk. Maybe give a training plan for that
- mobile apps: for Android maybe a PWA is enough, but can't do that for IOS ( I'd do it but Apple won't let me )
- better UI / UX
- social tools: share a GIF about your highest jump everywhere etc.
