Great Concept but executed poorly. I added 2 events between 6.30am and 9.30 but when I tried adding one for 10.30am it would let me, saying it overlapped with another event which it did not. I even checked my calendar and nothing was there for that time. It's now 11.42am, I tried adding an event for 3.30pm and it said its saved but hasn't showed on the clock or anything so it's pretty useless at this point.
