Could be the best with a little work, BUT...

This app definitely has the potential to be one of the best out there. You can search for patterns using a ton of different criteria, including designer, fabric type, category etc. I really like the ability to search for a pattern that matches a particular type of fabric that I have in my stash.
However, the app crashes on me every 15 min or so. It does seem to save all of your work prior to the crash though. Also, it is only letting me save 75 patterns to my wanted/already own list. This seems really counter productive to Simplicity if I want to purchase a lot of patterns and need to save them to my wish list.
Also, as many others have mentioned, it would be really nice to be able to purchase directly from the program. And many of the photos are missing. I have been unable to find any out of print patterns either, including ones purchased in the last couple of years. That makes keeping a database of my existing patterns impossible.
If the developers improved this app, Id be happy to purchase it. As it is, even as a free product, its pretty useless.
