No problems, worked

unlike another app I tried which only worked on the iPod touch, this one actually works on the iPhone 5s. Easy enough to use

I agree....the guy who gave it one star must be doing something wrong. It DOES work and it WORKS very well! Kudos to the author. PS dude....its not rocket science
