Great idea. One thing that bugged me out right away was the sign-up form: http://i.imgur.com/hfYmbXF.png

That needs to be a lot simpler and inviting. Let me play with the app first and then pitch me the membership and make it as light touch as possible. Keep in mind that I may see anywhere between 2 and 10 new apps a day and a speed bump such as the one you have up there doesn't make adoption easier.

Other than that, best of luck.
