This update fixes many, many bugs, most notably a problem with adding words during advanced study where the new words wouldn't show up (and sometimes would just keep adding). I can't even remember all the bugs we fixed, but yeah; go grab it:

After you update, we'd love it if you'd update your App Store / iTunes review of Skritter to point to the latest version, 'cause otherwise it doesn't really show up.
Another change we made in this version is to allow new users to start studying on Skritter, with lists and everything, before making an account. They can then name their account later when they want to sign up or change settings. Hopefully, this will be more friendly for people wanting to check it out beyond the tutorial.
This update doesn't have the example sentences in yet--we need to test them a while longer on the website first--but the next one will, oh yes!
