The great people at Scrappypedia have created an iphone app for this!!! There is a droid version in the works but no date for release YET!!! You can still use the online version to track your stash, and use a webcam to scan in your barcodes.
I am so excited over this!!!! WAIT....I forgot the best part....it's FREE!!!! Yes, FREE!!!!
I have downloaded the app which was easy and didn't take 30 seconds. You do have to log in with twitter or facebook. I used twitter because I don't have as much personal information on twitter. (I use twitter to follow celebs and news-more reading than posting really!).
There are instructional videos on their site for more information how everything works. I will be playing with my app tonight and write more later how everything worked out for me. It gets RAVE reviews on scrapbook.com forums.
