I am having the exact same problem as AAAME. After buying this program and downloading the sound files, iTunes will not back up my iPhone because the backup progress hangs forever. Deleting the program from my iphone solves the backup problem. Renkara, please fix this asap!
Otherwise, after playing with the program for a little while, I find it useful, but the process of adding words to ones own study set could be improved. I worked through about 100 words thinking I had added them, when I hadnt. If the user has only 1 study set, the word should be added automatically, without having to touch the set name to get the check mark.
But, first of all, the backup problem needs to be fixed before I can give this a thorough review.
