Keeps track of all I'd forget, and proves it! – TDF Tracker Review

Along with a good calendar and appointment scheduler, this app keeps track of my time spent, not only for proper billing, but to show accurately where the week went. Easy to establish categories and jobs, and you can quickly email the proof of your busyness to anyone who questions where you spent your time. This app can save a project when cuts come by quickly showing the project's need by proving the time invested.
