The one major short-coming of this app. (and most other "habit trackers") is that it does not have any option to calculate a total number (amount of hours, etc.) for a week or month--only a number of days or per day...That is a gaping deficit in these app's (with the exception of one or two with less desirable formats), as it is a far better way to track things like sleep which may fluctuate from.day to day. The other dismaying factor is that Habitbull doesn't seem to have any customer service, as I e-mailed numerous times about issues trying to upgrade (because it is a really helpful/useful application), and never got any response in about a year's time. :-\ Aside from the tabulation inadequacy discussed above--which I really hope they'll address/include that capability, it is a really helpful and useful app., and can be especially helpful for people with issues such as depression or "OCD" who may have difficulty keeping a handle on self-care and/or productivity (though, it could, also have the opposite effect, if people with "OCD" get too immersed in tracking things in their day-to-day :-S). In general, it is a good tool to have, though, and can help you make a lot of progress on things like household projects, etc., but I really do wish that they'd adjust it so that you can calculate a total for a duration of time longer than a day, and that they would also be conscientious about customer service/support and responding to/fielding correspondence and issues people encounter. ~*Kristin Star*
