Great App - Not buggy anymore

I have not had any crackling sound issues since the developer corrected the problem in Version 1.3. As a result, Im giving it four stars - up from three. The five star rating will come when users can add their own tunings in a later version. If this happens - this could be the best app available for tuning instruments. Loving it in the mean time. Heres hoping.
