Once you start up the app you will see an overview of the current week that's split up into eight fields. Seeing as the week only necessitates seven fields the eighth is used as a monthly overview (similar to what you might be familiar with if you've used the Windows calendar). Long press on the month overview and a dialogue window pops up via which you can jump to any given day.
This view affords all sorts of options. Swipe down to get to next calendar week, up to get to the previous one. You can also check the month and day views.
Long press on a day in order to make an entry (including time details). A new menu pops up in which you can add details regarding when the appointment will end as well as an option for giving the appointment a name. A reminder is automatically set up for 15 minutes prior to the appointment, and more reminders can be added.
Editing or deleting an appointment is a piece of cake: simply tap and a pop up window with lots of options opens up. This includes displaying the appointment as a QR code, which you can then scan with other devices in order to have all of the information with you.
aCalendar - Android Calendar also features a moon calendar and birthday entry option. It even integrates events and invitations from Facebook!
In short: there are tons of settings and editing options, ranging from switching the moon calendar on or off to just about everything else.
aCalendar - Android Calendar offers a wide range of options that users can play around with and adjust according to what suits them best. There are lots of fun, innovative features that should please even very experienced calendar users, such as the QR code option and the moon phase calendar.
Adding appointments is a cinch.
Screen & Controls
To be honest, I found aCalendar - Android Calendar to be somewhat muddled at first. Once I got used to controls I found it easy enough to navigate however, and found its set up and controls clever.
The UI is a bit imposing at first, but that's because it comes with a bunch of settings options other calendar apps don't have.
Speed & Stability
aCalendar - Android Calendar runs smoothly and without major lagging although, it being a comprehensive app, there is some minor lagging here and there.
aCalendar - Android Calendar is free of charge and can be found in Google Play. It has tons of functions and it's free—what more can you ask for.
By the way: if you love the app and want to support the developers you can also download cCalendar+ for EUR 1.99. It comes with a widget that has a month view, sharing feature and settings related to privacy and availability. More features to come, according to the devs!
