Words can't express how cool this is. I wasn't expecting the voice recordings, but they are there (not to mention in relatively fine quality, given that I listened to the pronunciations through the iPod speaker--not headphones).
In terms of the written transcriptions, I was delighted to see that ejective and stress markers are easily distinguishable (even if they weren't the recordings should help in that regard). Otherwise, it's not all-out IPA transcription, but it's close and easy enough to understand in context or with the help of recordings (for example underlined "a" is a reduction/schwa).
Overall, this is just a delightful app for anyone even remotely interested in the language!
