Really good. Pricey though.
It's a wonderful all-in-one tracker, notepad, calendar, reminder, etc. Of course as with everything all-in-one, you'd think it wouldn't do any of them particularly well, but this one works great, provided you take the time to setup your system and invest effort and time in constantly using the system in managing or improving your life. I got it while it was on sale (free), which is good cos i would never have bought it at full price without knowing exactly how it works and how it'll benefit me.
