Fantastical vs WeekCal

If you're locked into using an Exchange account, Google Calendar won't work without 3rd party syncing options. Fantastical works flawlessly with Exchange and with Google Accounts so you can have both. It also supports iCloud, Office365, Yahoo, and Facebook calendars.

You can copy and paste a line from a meeting note and Fantastical can copy down and present the relevant information

Week Calendar includes templates, which are files containing one or more events that can be duplicated from week to week. With each event, information such as address, time, or duration can be copied as well. This comes in handy for routine events like work, school, or exercise.

Week Calendar supports dropbox file attachments in collaborative calendars so other people are able to quickly see files relating to an event.

With the action menu, users can use up to 40 kinds of automated actions.

Just like with apps on the home screen, events on Week Cal can be moved with a tap and hold gesture.

Week Calendar displays a day's events just by tapping the date. The data can be tapped directly from year view.

Best thing is being able to set different colors, if you have multiple events during the day it really helps to set different colors to easily get an overview for school lessons as an example.
