Hello, I wanted to get any recommendations on flashcard apps. I need to study up on a new aircraft I am going to pilot, and was looking for any suggestions from others how have actually used these programs. It would be easier to create the cards on a mac, as typing is much easier than the iphone. I would also like to be able to upload/transfer the cards to other pc/phone users in the future, either via direct download or a link they can use. Of course, randomizing the cards, and tracking errors are also important features. Any suggestions?
