As a designer, if you search for Iphone apps to suit your needs, you end up finding a lot of them, even on lists made by other designers, that are not actually useful and don’t justify their price. I wanted to check the market for Iphone apps to see how they can improve my life as a designer since a friend of mine was interested in creating apps. From what he told me, it seemed that a lot of time and effort was invested in these applications and that meant only good things for the ones that will use them, that is a promising thing with high expectations. So I investigated throughout the AppStore to collect the most useful apps for a designer or developer. I was glad to find out that some of these are free, only some of them. For the rest, the price per quality rule applies.
