A tempo bom detector with haptics for watches to help social dancers stay on beat.

I have heard from many dancers that they would love to have an application for their verbal watches that could listen to the music, understand the tempo, and give them feedback. Haptic feedback to stay on tempo on beat. Also, it would be ideal if it could recognize the phrasing of the music, the one and five, for example when you dance bachata or salsa
