There are several available, Fabric Stash is one of my favorites, and one of very few apps I have ever paid for (I think I paid for it!!) It is awesome, lets you take pics of fab and "catalogs" them!!! Love it, they also have an app called Pattern Pal.....then there's Quilt Fab and a couple of others that I know of you can search quilts, or fabric, or sewing.....
