I like that you can track your time using this app, it's easy to use as well! Sometimes there are glitches when logging in but they usually fix them within an hour or two so not too much of a problem for me personally.
It does take some getting used with all their features however once everything is set up correctly (which isn't difficult) then tracking tasks becomes very simple which makes my life easier because now i have accountability for what hours go where every month - something we never had before!!
