Recently I was realizing how horrible the built in calendar app was. You can barely even see the events because theyre crammed below the month view. So, i decided it was time for a change but I was unsure of which calendar app to get. After some searching I narrowed it down to Agenda, Calvetica Classic and Tempus. I ended up buying them in that order. (I ruled out Calvetiva v4 because generally people seem to think it has so many features that it became harder to use. I dont need or want a task manager with my calendar. Wunderlist works great for that as a separate app. What I was looking for was speed, simplicity and ease of use.) After trying all three, Tempus is by far my favorite. If youd like some comparison, read on.
Agenda was my first purchase, and I nearly stuck with that. The scrolling week view was perfect and easy to use. The problem was that it used the built in calendars event creation page, with its multiple taps. It just takes too long to create an event. Plus, of these three apps, Agenda has the biggest footprint being over 3mb. Not big, but I like lean apps.
The next one I tried was Calvetica Classic. This one had much faster event creation and seemed quicker all around. Small footprint at 1.7mb too. However, after getting used to the scrolling week events view of Agenda, the click on date and press back button after method just seemed like too many steps to view a days events. This brings me to Tempus.
Mysterious Trousers really got it right here. It took the best parts from Calvetica Classic and Agenda and combined them. Smallest footprint of all three at 1.5mb. Super zippy performance. Scrollable weekly events that can be set as the startup view (although default is Month view). Easy gesture based controls. Plus, the most options of all three. One option I was especially happy to see was the ability to change the color of calendars from inside the app. With the others I had to go to the default calendar apps settings. Overall, this is exactly what I was looking for. Congratulations to Mysterious Trousers for getting it spot on!
