Once great, now buggy.

Ive been using Mental Case for several years, now. It used to be a fantastic, easy to navigate SRS flashcard app. Over time, development has focused on a flashier but less appealing user interface, & has done so at the expense of speed & stability. Ive used the current app on two MacBooks & two iPod Touches. It has crashed frequently on all. iCloud sync is unreliable, & I often cant update my study deck for days. I used to hold out because I figured that kinks would be worked out thru updates. After years of decline, however, I now only stick with Mental Case because I havent made the time to learn Anki.
