My first thought: What should I do here? Ooooh, two shiny buttons! tries one. Huh? Oh, I should probably start in that tiny, tiny bar…
I also thought it was odd that the "you should upgrade here" balloon pointed at my status bar.
before i would sign up (and 2.99 seems fair. doubt i would pay more) i would want to see some reports, and i would want an android app that is equally as easy to use.
