I’m trying this iPhone app called TimeGolden. It’s for figuring out how you spend your time, among other things. Pretty interesting so far. If you can deal with all the Help info written by a non-native English speaker, you can learn it with a little playing around. So far I like it.
Here’s what the developer says about it on the app store: “Quantified Self Time Tracking — TimeGolden is a new generation of time management tool which adopts TimeStamp tracing mode, and has virtues of to-do list and mind mapping etc.”
