What is aCalendar?

aCalendar is an excellent alternative to the out-of-the-box calendar, which is much wider in terms of functionality, and also has a more beautiful and friendly interface with a spectacular design. First of all, this application is aimed at business people who live in a high rhythm, for whom drawing up a plan and strictly following it is a priority – this calendar will remind you of upcoming business and events, allowing you to do everything on time and not lose sight of anything. You can interact with the program in two modes, combining them if necessary.

The first format aCalendar is presented in the form of miniature tiles, inside which primary events and tasks for the current day are marked in different colors. The second format allows you to consider in detail the list of tasks for each day, which is useful if a person has quite a lot of them, and everything is scheduled, so to speak, by the minute. It is worth warning about some inconveniences in using this novelty, the fact is that all events are automatically duplicated with a built-in calendar, so it is possible to receive a large number of notifications for the same event from these two applications.

In order not to enter the aCalendar program every time, you can use the convenient and nicely designed widget (there are seven options). The process of navigation in the application is simple and involves the use of the user’s usual gestures (tapa, swipe, drag), as well as side volume rockers. You can advise the utility to people who want to get a calendar with a design that is different from the built-in application, which has more functionality and flexibility in settings.
