Allows much more customizability than other timer apps I've found. That means I can keep my schedule in the Goldilocks zone of productivity and enjoyment. Thus I don't need to keep using willpower to reset it every time I want to avoid certain sites, and don't risk "forgetting" to use it.

However, the UI could be more intuitive - I often accidentally set it to do things I don't want. The override also doesn't work for me even though it displays a messages saying it has. This is a problem when I need to use certain sites. It happens whether I activate override before or after I run out of time.
