Yarns found in Mary Beth Klatt's app, Yarn U, include Berroco, Debbie Bliss, Rowan, Classic Elite Yarn, Noro, Cascade Yarns, as well as the Knitpicks line, just to name a handful. Yarn can be searched for by weight, manufacturer, fiber, and washability through the handy filter tool at the top of the screen, or by scrolling through the entire list. For each yarn listed, there is a picture and a brief informational section that includes manufacturer, yarn weight, stitch gauge, fiber content, and yardage, as well as pros and cons of that particular yarn.
Bottom line: Yarn U is a convenient and helpful app for knitters and crocheters who frequent local yarn stores or shop online for yarns, who want to know more about a certain yarn at a glance, and are handy with an iPhone, iPad, or iPod (and soon Android, as Mary Beth Klatt tells me).
To find more information on or to download Yarn U, visit the App Store.
