Do you ever get lost in a project and wonder where the time went? If so, you should consider downloading 30/30, an app that keeps you on task.
It lets you set up a list of various jobs, each with a designated amount of time to complete them. Start the clock, and when it runs out, it will tell you to move onto the next thing.
30/30 helps you focus in a clean, colourful interface that you can control with gestures. Say, hypothetically, you tend to get lost down a YouTube rabbit-hole (not that any of us knows anyone like that). You could say you want to spend 30 minutes looking at videos followed by an hour working on your taxes. It alerts you when its time to move on so you don't waste too much time.
30/30 is a free download for the iPhone and iPad
