Great app!, nothing but good things to say (its the best FC app out there).
One thing I would love to have added (event if its somewhat counter intuitive to the application name) is a multiple choice option/mode (these are indispensable when studying for certification tests). I know you can create the card to show multiple choices with the correct answer on side 2 but it would be great to have the ability for the answers to be randomized each time the card is displayed and graded by selection (and of course being greedy the repeat card features you already have would be great for this review method as well). I've searched the app store and there are few 'create your own' multiple choice tests for iPhone and none iPad.
Even if you don't opt to add this request - thanks for a great App
