Technical Made Easy, an American software company has a number of really great iPad and iPhone apps. The Knit-n-Count is particularly easy and useful.
I have come to use this regularly for working with lace or sweater patterns. I can add simple row and pattern repeat information so that as I knit and press the big green button at the end of each row the app records where I am in the pattern, sounding pre-set alerts for moments when I need to take note of the pattern once again. This easy to use app has made travel knitting so much easier… it has also helped me when I was too busy to knit, as coming back to the pattern I knew exactly where I left off and what I should be knitting next.
Check it out on iTunes and on the developer’s main site at http://www.technicalmadeeasy.com/
Have a wonderful day...
