I have only started to use it but I think it will be great. It is simple and it organizes tasks into the only categories you really need which is whether or not they are important and urgent. I would like to see the app sync with a website so that I can work from a computer if I dont have my iphone or iPad. I also would like to have the ability to see competed tasks. Overall I really like the app mainly for the simplicity and how it divides tasks in accordance with the seven habits.
