Golf Pro Tempo

Edit: developer was really responsive and added all the improvements I suggested below. Changed my rating and am happy with it. Bought it for more speeds but I found that I preferred Speed Level 5, there is only one speed faster and I think I have a pretty slow swing speed. You also can’t customize at all, only the six presets. Most of the sounds are not good except Piano. Lastly there are no traditional music controls via lockscreen or headphones so it’s a real pain to open unlock your phone, open app to pause it

Tempo drills really help, and you can lock the phone and it keeps playing over headphones or speakers.

I like that this app is simple and serves a single purpose. Would be better if there was a count down to the first backswing tone, but otherwise I think I could just get use to it.
