We're in the process of designing an app that would behave well with tablets in the future when creating flashcards, but for the moment, Anki's your main option. The current process of creating flashcards involves having a few websites (Google Images, perhaps a dictionary, possibly forvo.com for audio files) open along with Anki, and dragging content from those websites onto boxes in Anki's input area. It's not something that works on Mac tablets. As for PC tablets, if you can easily switch apps and drag content from one app to another app, then that could work. We'd suspect something like a Microsoft Surface might be able to handle that, though we haven't tried it personally. If at all possible, a laptop/PC/MAC would be the way to go as far as Anki goes, especially if you are new to Anki.
