Does what its supposed to. Same as the Hipstamatic film, but the obvious advantage to this app is that it also uses the front camera for portrait work. And thats the whole point of this, since TinType film works particularly well for portraits.
Im pretty sure plenty of Hipstamatic users have been requesting just such a film for front-facing camera work. Well now we have it. Cant really complain about that.
