First one needs to know basic functionality
is it a sports calendar, a shift scheduler or a general use calendar?
I say this because I am brainstorming myself with a name for a similar (or not so) app.
My girlfriend is a cleaning lady and sometimes has trouble keeping up with the schedule and with month's stats and individual incomes/client...
for the moment I settled with "Cleaners Diary" but "Cleaning Lady Log" is a strong possibility too...
"DaysWare" to me sounds more like a clothes app than a calendar...
"App2Date" sounds like an app updater...
