[Question] - Running/Fitness Music App

My apologies if I am posting "without due care and attention". I read the rules and did my best! First posted in r/androidapps - it was suggested I re-post my question here:I am primarily a music composer and producer - not an App Developer. I use a DAW (Propellerhead | Reason), which provides the ability to change the tempo of a music track (BPM) during the editing and composing process - without detriment to the pitch, tone, chords and melody. Tracks can be output in high quality as .WAV, .MP3 and - with some degree of detriment - as .MIDI. I am looking for interested App Developers to collaborate on producing a new type of Running/Fitness App, which allows the user to set the tempo (BPM) of their chosen tracks (which I will produce) - or to chose an automated setting which utilises the smartphone's gyro- or cardio-features to determine a pace/beat and set the tempo accordingly.According to the research I have completed, no such App exists - although there are many fitness/music player Apps - none have a feature or function which sets the tempo to a user-, gyro- or cardio-specified requirement. I'd be happy to be corrected on this research, if such does exist!Thanks!
