I found an iPhone app that I'd love to see for Android. I'm a knitter, and I mostly knit charted lace. I use my tablet (Asus Transformer Prime) for my patterns, but it is hard to keep my place in complex charts.

knitCompanion - Join the Knitting Revolution!
I contacted the developer, and they say they're not able to create an Android version of the app. I do know lots of other knitters using Android devices that are interested in an app like this. I'd be willing to pay, too.
Specifically, I am looking for an app that you can mark what row you're on in a charted knitting pattern. It doesn't have to be as complex as Knit Companion.
Here's an overview of charted lace knitting.
All I need the app to do is to mark what row I'm on. That's it.
