Good value
Ive found this app to be the best of its kind so far. The variety of options it offers to learn a song are well thought out. The sound remains clean when the recording is slowed down, which is essential. The chord recognition feature often supplies too many chords, but you can figure out which ones are most important. Pretty easy to use, fairly intuitive. One thing I havent found is a button to return to the start of the song. Seems pretty basic - hopefully it will be included later.
