Started using RescueTime today and it's fantastic for knowing how you spend your time on your devices, such as your computer or your phone. The coolest feature is the productive/distracting thing: you can see how much time you spent on work today and how much on distracting apps/webs! Definitely a must-have for me. No app for iOS though...
