This app is so much fun. It does basic draw downs and has a color wheel picker. It is fairly easy to figure out, but I suggest you play with some of the samples and learn how to save and manage files and poke all the icons/do the different things before starting to work on your next real project. You can save as wif files which can be read by the computer programs and you can print. The woman who wrote it is a weaver, so she knows what she is doing. If you want to add on yardage estimators and heddle counters and things like that, there are add on packs for $7 each. Even if you bought everything it would still be a third the price of a computer sized program. Its not so fancy as those, but it does everything I need, it is a sixth the price and I can do it on my iPad! I have had zero problems with crashing or anything like that.
