aCalendar review
A calendar-focused Android app with eight widgets and views from day to year.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
aCalendar is an Android app for managing events, birthdays, and Google Calendar data, aimed at people who want calendar views and widgets on their home screen. Its day, week, month, agenda, and year views bring different planning horizons into one calendar app. Eight widgets offer a calendar-specific alternative to assembling a broader set of home-screen tools.
Calendar synchronization runs through Android’s native calendar backend. aCalendar supports flexible event recurrences and birthday calendars drawn from contacts or created without contacts, and it can export calendars as ICS or CSV. Optional task management connects with Google Tasks or CalDAV/OpenTasks. These features make it a fit for users whose planning centers on calendar events, with task handling available as an adjunct rather than a general widget-builder feature set.
The free version is ad-supported and has optional premium in-app purchases. aCalendar+ is a separate paid app and includes available in-app extra purchases; the vendor says upgrades are one-time purchases rather than subscriptions. That gives buyers a free way to start, while the paid route is a separate app rather than simply a named tier within the free version. Choose aCalendar for calendar views, event management, and dedicated calendar widgets on Android. Look elsewhere if you need a custom widget builder or widgets for weather, music controls, shortcuts, notes, or tasks.
