Add practice tracking app

I bought the Sound Brenner Core and it was absolutely amazing! But during my school day it had slipped or of the magnet. Unfortunately costumer support told me that they could not replace it for this mishap. If future versions had an in app tracker for the watch Itself I would buy it again. This is a great product and that can help many musicians improve.

Hey, it is not announced yet but we are currently working on a new version that will bring a Tracking app to the device itself :) It will be announced later this year

Changed the status to "Completed"
