aCalendar vs Google Calendar

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

Google Calendar

• Anyone who already has a Google Account and wants a free calendar
• Organizations standardizing on Google Workspace for mail, files and meetings
• Taking bookings through a single free appointment page

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.

Google Calendar

• The paid version is only sold as part of Google Workspace, which also includes Gmail, Drive and Meet.
• Personal accounts and Business Starter get one booking page; extra schedules, payments and reminders need Business Standard or higher, or an eligible Google One plan.
• Time Insights and working hours and location are limited to work or school accounts, and Time Insights can only be viewed on a computer.
• No desktop app is listed; Google offers it on the web and as Android and iOS apps.

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.

Google Calendar

Appointment booking pages

Publish a page where others pick a time on your calendar. Eligible paid plans allow several schedules, Stripe payments, email verification and up to 20 co-hosts.

Shared and layered calendars

Create calendars shared with a team or a whole organization, and view several calendars together, color-coded by category.

Scheduling from Gmail with Gemini

On Workspace plans, Gemini in Gmail can suggest meeting times and add events detected in an email with one click.

Google Meet and attachments

Events can carry a Google Meet video link and attached files, so the call and its documents open from the invitation.

Time Insights and working location

Work and school accounts can see how much time goes to meetings and who they meet most, and can share working hours and location.

Tasks on the calendar

Items from Google Tasks appear on the calendar next to events.
