I want to build the ultimate iPhone app for times table practice. The key thing about this app is that it should LOOK fantastic. I therefore want a designer with a large amount of experience and who can show me the previous projects he/she has worked on. The app needs to test both adults and children on their ability to do times tables up to 20. It should have a number of different ways to test this. It needs loads of features, for example it should keep high scores, previous results, times tables which a user gets wrong and those which they get right etc. I have not developed a full spec for this yet and I am open to ideas about how this can be done. Please PM me if you want a more detailed spec and give some sort of estimate of your cost. As I said, UI and graphics are very important to me, if you have ideas about possible themes or anything like that, let me know. I am very open for the designer to have a large amount of input.
