Cool idea. Unfortunately I signed up and linked my fitbit, and it didn't load any of my data. Though I did enjoy the "creating suspense.." loading animation.
Ha, glad you liked that part. Right now it's setup to only show the last month or so of data, so if you haven't tracked any steps since 3/27 it won't show you much. (if you've logged some steps since then though, please shoot me an email and we'll figure it out!)
I use it every day, including tracking separate workouts so it should be loaded w/ data. Now it's telling me 'something is wrong with my username' when trying to login. Where can I find your email?
FYI - on a side note, I'm the creator of fitbolt.com, which also integrates w/ FitBit. It's cool to see the different uses of their API people are coming up with!
