It's got most of the data from the latest copy of Spocalc in it but you can add your own data just like with Spocalc.
Features:
* Lots of rim and hub data * Anyone can add data without registration * It will remember the rims and hubs you've used and make them available to you in convenient menus * You can get a link to a certain build for easy sharing/bookmarking * Works well with the iPhone
I would appreciate any feedback (off-list) that you have.
