Hi Cassandra,
The one thing that drew me to Toggl.com is its flexibility on tracking time. At first use, you can toggle your time on/off per task. And from there you could gauge how much min. or hours you spend on a certain project/task. From there you can fix up a time to finish per project. Time tracking is just a Toggl On/Off. And the reporting system is great to! And the best part is, its very easy to use, compared to Rescuetime.com. Ill elaborate further in awhile. Need to go take a rest. Ive been up for more than 24hrs now!
