We recently upgraded our cell phone service and ended up with Android phones that have "apps", which our old phones didn't have. The pre-installed apps don't appeal to me-- mostly games and such.

Can you recommend any useful apps for needlework enthusiasts? Where do I go to get said apps?

On my phone you go to a place called "MarketPlace" and there are tons of free apps. Good luck.

I just found one from Robert Kaufman and Quilting Paradise it is a quilting calculator that helps with quit a bit! It seems to be he only one though right now I have been waiting for others!

Also search for quilting and what ever other hobbies your interested in :)

Are there any apps for the ipad on quilting

Yes, not that I know how to use them.
I have quiltref, quiltfab, quiltcalc, blockfab, and quilting

Blueshift Software has several iPhone apps: Fabric Stash, Fabric Journal, Quilt Helper and they are working on others.

There are also apps for color selection, drawing, photo editing, one called Stitch Minder for knitting. Lots of them out there and more coming all the time!
Here's the Color Wheel one. http://itunes.apple.com/us/app/color...320157374?mt=8
