Good but needs extra features

For what this app does, its actually pretty decent. I was hoping for a tuner that actually listens to the strings and tells you flat or sharp, but instead it actually plays the notes and you tune your strings to the notes.

But it works surprisingly well. I have a super-sensitive acoustic 12-string (pain to keep In tune, even with my perfect pitch) that I actually tune to standard tuning, and this app helped me get the tuning down perfectly in under a minute.

This app is very bare-bones. No config, no nothing. Just tap the string you want to tune, and youll hear a sampled guitar string tuned to the proper note.

I had no trouble running this on my 16-gig iPhone 4 w/iOS 6. Dont know why others had trouble. Perhaps you need to try double-clicking your home key and shutting down those other apps running in the background?
