Show HN: Cadence Sync – Run to any song, at your perfect pace

I love running to music but most songs are always just slightly too slow or too fast. Finding one that matches your exact cadence always feels awesome, and I thought-- there should be an app for that. So this is an attempt to make that happen for any song you have. Still ironing out some kinks here and there, but seems to work pretty well. TestFlight build available if you want to give it a shot.
