Im writing my dissertation and Ive tried other similar apps. This one is far superior. The various settings are very helpful. I also really like that I can track my progress over time. It is easy enough to say, oops I guess I didnt make my goal today, when the evidence would disappear by morning. But if every day is logged on a graph it is easier to hold myself accountable. One suggestion would be to start averaging with the first day. As it is now each day of work is averaged against the previous 30 days which is demoralizing when you just start.
