Block Tool is perfect for a quilter. Has 102 common blocks in 5 sizes. Worth the $5 if you commonly struggle with figuring out what to do in a hurry for that next baby blanket or gifted lap quilt. If you already have Electric Quilt, the app is redundant. Quilt Block is by C&T Publishing.
Sewing kit is an app created for sewers. You can store your inventory of patterns to take with you. Each pattern has a place to keep yardages. While it can be used for quilting, it is clearly designed for garment sewing. You can create projects linked to pattern and fabric as well. I loaded it with 42 garment, accessory and household patterns. If you load the manufacturer and pattern number, the app searches a database for current patterns, and adds photos if there are any. If not, you can take a photo to add to the pattern.. I had a few crashes when taking photos of patterns not in the manufacturer's database, but it was still fast. I did it while watching 2 episodes of a Brit crime drama on Netflix.
Finally, many cross stitchers and other crafters like to keep track of the time worked on a project. If you charge $$, then you certainly need to do that. Hours tracker is intended to be used by jobbers. At $5, it's a good choice for cross stitchers as well. It runs in the background, so uses less power. It will also keep a history of your job. Do you need it? Nope. There's a free stopwatch as part of the programming even on a nano. Gadgets. I love them.
As I find other apps that are useful, I will tag them. Ok, well Polly is knocking over everything so that I will go to the quilting sewing area, so I will post another time. But, not by ITouch. This took forever to type.
