Does not do anything – DataRocket - Track mobile data usage widget Review

I had the app for a couple of days now, but the startscreen still reads "0Bytes", when in fact I have used about 200MB. Swiping to the right gives sort of a static result and another one on top of it. None of those make any sense. This is either broken or a bad joke.
