My favourite (and Ive tried them all!)

Dont like the name, but everything else works just great. I have had questions answered in minutes, so support is good too. The app has many, many options, and you can get lost and confused in there, changing stuff, but as they say, thats a feature, not a bug. I have used it with the Google calendar, and now just with iCloud, and I like it either way.
