The app works as advertised, although for 3.99 it doesnt work any better than the other free one that I downloaded. The description is a little misleading, as it claims to dial directly from the calendar...note that they are not referring to your native calendar...its the calendar within the app that you have to dial from. Also, the app doesnt recognize events that are tentative on my calendar, so I still have to manually dial those, but the free app didnt have this problem.
dumbbear about ApptDialer, v3.8
