Not free
Couldn't be bothered
Garbage, at least for me
Secondly, it looks as though your inventory is held on a server somewhere, not your device (you can't do anything until you create an account and you can't create an account without state/zip, so I can't be sure). If the inventory IS in fact held locally, why does it insist on account creation?
Thirdly when it complains that you haven't completed all fields, it doesn't highlight the missing ones.
Very disappointing.
