Sample rate issue
I installed this on an iPhone 6 with iOS 9.1, recorded a quick voice memo (mono, 44.1, 128), and emailed the file to myself. Upon playback within the iPhones Mail app, it sounded like the file was playing at a slower speed/lower pitch. Havent checked to see the actual sample rate, but this will need to be fixed before this app can be useful.
