DigiCal vs One Calendar

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

One Calendar

• People who mix Google, Microsoft, iCloud and CalDAV calendars
• Households or workers split between Android, iPhone and Windows
• Buyers who want a one-time payment and no subscription

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.

One Calendar

• A Premium license is needed per platform group: Android, iOS and Windows are each bought separately, because the stores do not allow cross-platform licensing.
• The free version syncs 6 months of past appointments and leaves out search, theming and appointment colors.
• The Microsoft Store page lists the Windows app as free with in-app purchases but does not show the Premium price.
• No web or Linux version is listed. Printing and automatic day rollover are Windows-only Premium features.

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.

One Calendar

Many calendar services in one app

Connects to Google Calendar, Outlook, Office 365, Exchange, iCloud, Yahoo, GMX, Synology, Nextcloud, ownCloud, Mailbox.org and other CalDAV servers, and shows them together.

Five views with week numbers

Day, week, month, year and list or agenda views, all with week numbers. A quick filter narrows what is shown by calendar color.

Appointments and invitations

Add, change and delete appointments, set up recurrences, invite people to a meeting and accept incoming invitations. Appointments can be shared through apps such as WhatsApp.

Works offline

Appointments can be viewed and managed without an internet connection, according to the vendor's feature list.

Widgets and live tiles

Several widgets are available depending on the operating system, including live tiles on Windows. Choosing which calendars, birthdays and tasks a widget shows is a Premium feature.

Theming and colors

Premium unlocks 170 color options, a background picture, a custom text color and predefined themes, plus a separate color for any single appointment. A dark theme is supported.
