From the Rav group:
knitCompanion is designed to turn your library of PDF patterns into highly interactive knitting instructions! Its patented^ knitter inspired design enables you to interact with your patterns like never before. For the first time, you will be able to easily use the patterns in your PDF library directly in electronic form. No more flipping pages to find your key or knit a larger chart. You get reminders as you move along your rows, so those pesky “at the same time” instructions appear right when you need them. Supports advanced capabilities for charts and written instructions including row markers, stitch markers, highlighting, and much more!
Currently the product is only available for Apple users, but the developer is trying to develop an Android version and is using Kick Starter to fund it. The campaign ends tomorrow morning.
I don't have any affiliation with the company or the app and won't receive anything in exchange for this post. BUT, I really want to see this app for Android. Several friends have this app and love it and I love what they can do with it. As of now there is no app for Android users that comes close to what this app can do.
So, if you get a moment please check out the Rav group and if you think you might be interested, please consider contributing to the Kickstarter.
That's all from this side of the screen!
