Almost perfect!

One thing that has to be fixed is inability to read extra long names (because they are incomplete and simply end with an ellipsis). For example, have a look at "Actinobacillus".
Well, as I have already mentioned in Drug Pronunciations.app, please, consider audio replay, alphabet column on the side and right-on-touching-names audio playback. Agreed with the aforementioned suggestion: make them icons prettier (for both apps)!

PS: I always re-rate. ;-)
