Timing 2 for the Mac is a really fantastic time tracking tool. Why would you want to track your time? There could be multiple reasons, but it could be tracking time for clients or just holding yourself accountable. Timing 2 offers automatic tracking (with options for manual), so this lets you easily track without having to actually remember to track.

At the end of the day, it builds a fantastic interactive graph. It also has automatic suggestions for blocks of time that belong together. This lets you assign hours of time at once to easy categorization for clients.

I ran Timing 2 for a few months before writing about it here. It's really easy to use, and requires no cloud service (all of your data stays local).

You can buy Timing 2 for $29-$79 depending on which version you want. There is a free trial available.
