aCalendar vs DigiCal

aCalendar

• Android users who want a full calendar without a subscription
• People who want Google Tasks or Microsoft To Do lists inside their calendar
• Anyone who prefers to buy only the upgrades they need

DigiCal

• Android users who want more views and widgets than the stock calendar
• People who like weather forecasts next to their appointments
• Following sports, TV or holiday calendars inside the schedule

aCalendar

• Android only. The vendor states there is no iOS, web or PC version and that none is planned.
• The free version shows ads, and tasks, attendees, profiles, public holidays and the wider color choices all need a paid upgrade.
• In-app upgrades cannot be shared through Google Play Family Library; only the separate aCalendar+ app can.
• Licenses are tied to the store account and cannot be moved between Google Play and Huawei AppGallery.

DigiCal

• Android only; no iOS, desktop or web version is listed.
• The free app contains ads. The year view, the two month widgets and the widget color picker need DigiCal+.
• The premium weather forecast is a separate yearly subscription, priced at €2.50 on the vendor's site, and is not included in DigiCal+.
• Google Play shows in-app purchases of $1.09 to $5.49 per item without naming them, and the site gives no price for calendar subscriptions.

aCalendar

Day, week, month, agenda and year views

Swipe vertically to move through time and horizontally to switch views. Day and week views can show a mini month or a graphical week overview alongside.

Eight home screen widgets

Widgets include agenda, date, day and week layouts and a birthday widget added in version 2.9. Accent colors can be set per widget with the Colors upgrade.

Tasks next to events

The Tasks upgrade shows to-dos on their due dates in day, week and month views, with subtasks and a tasks widget. It works with Google Tasks, Microsoft To Do, CalDAV through Tasks.org, and local lists.

Business features

An upgrade adds attendee management, linking contacts to events, free or busy status, private events, and profiles that separate work and personal calendars.

Print and export

Calendar views can be printed or exported as PDF or PNG, and events exported as ICS or CSV files. Multi-select applies an action to several events at once.

Uses Android's calendar sync

The app runs no servers of its own. It reads and writes the calendars Android syncs, including Google Calendar, Microsoft Exchange accounts and CalDAV servers, plus local calendars.

DigiCal

Seven calendar views

Agenda, day, week, week agenda, month and text month views in light and dark themes. The seventh, a year view with a heat map of busy periods, is part of DigiCal+.

Six widget types

Agenda, day, day list and day grid widgets come with the free app, and DigiCal+ adds text month and month widgets. The site lists nine preset widget themes, and widgets can go on the lock screen.

Syncs with Android calendars

Works with every calendar server Android supports, including Google Calendar, Outlook.com and Exchange. A local calendar that does not sync is also available.

Built-in weather forecast

A free 3-day forecast appears in the calendar and widget views. The premium weather subscription extends it to 14 days with a graph and several saved locations.

Calendar subscriptions

A catalog of public holidays for more than 100 countries, sports fixtures, TV schedules, religious days and company events can be subscribed to and added to the schedule.

Location search and action bar

Typing a place name fills in the address and adds a map. Tapping an event opens an action bar to move, copy, edit or delete it, and notifications carry snooze and navigation shortcuts.
