I did a writeup about the service and the app. I like the service, the app is bad (for now), but if it's important to you to support your local indie store (it is to me) and don't mind the walled garden (I do, unfortunately), it's a pretty good start considering it is day one of a new system.

A more technically sophisticated person than me could probably find the source files, but I couldn't.
