CalenGoo vs Merkuro Calendar

CalenGoo

• Google Calendar users who want more views and settings than Google's own apps
• People who want to pay once per platform and avoid a subscription
• Anyone who wants calendar, tasks, contacts and email in one desktop window

Merkuro Calendar

• KDE Plasma users who want a calendar made for their desktop
• Linux users syncing Nextcloud, Google or Exchange calendars
• People who keep tasks and subtasks next to their events

CalenGoo

• The iOS, Android and desktop versions are different apps and each is bought separately.
• There is no free version. Android has a 72-hour trial and the desktop download can be tried first, but no iOS trial is listed.
• The desktop app costs $49.99 on the Microsoft Store; the site gives no price for the in-app purchase in its own downloads, and says Linux support depends on the distribution.
• Online booking is a separate product: the Booking System is free up to 20 booking hours a month and about $10 a month after that.

Merkuro Calendar

• Stable releases are for Linux. The Windows builds on KDE's site are nightly installers that KDE labels unstable and intended for testing.
• It depends on Akonadi and KDE PIM packages; without kdepim-runtime, the project says the calendar component is heavily restricted.
• The Kontact Flatpak that includes Merkuro lacks some desktop integration, such as the calendar applet plugin, so KDE recommends a distribution package.
• Proton Calendar cannot be connected, and services with non-standard calendars or task lists, such as Todoist, are not supported.

CalenGoo

Direct sync with Google and others

Syncs with Google Calendar, including all past and future events, and with iCloud, CalDAV servers such as Nextcloud, Exchange and the device's own calendars, depending on the platform.

Configurable views

Day, week, month, agenda and year views plus a landscape day view and a search view. The month view zooms and scrolls, and nearly every part of the display can be adjusted.

Tasks in the calendar

Google Tasks lists sync and appear on their due dates, with sub-tasks and recurring tasks. Small task lists can also be saved inside an event, such as a shopping list.

Templates and floating events

Events can be created from one template or several combined. Floating events move to the current day until they are completed, and drag and drop moves, copies or deletes entries.

Reminders, contacts and attachments

Up to five reminders per event by SMS, email or pop-up. Contacts can be linked to events, and files and Evernote notes attached.

Desktop app with movable panes

The desktop version arranges calendar, tasks, contacts, templates and email in panes you can drag around. It includes an email client for Gmail, IMAP and Exchange and a free-text quick add.

Merkuro Calendar

Month, week and schedule views

The month view gives an overview of the whole month, the week view shows each day hour by hour, and the schedule view lists upcoming events in order.

Tasks and subtasks

A separate task view shows tasks and their subtasks as a tree, with filters that can be customized.

Local and online calendars

Supports CalDAV calendars such as Nextcloud, Google and Exchange calendars, iCal files and folders, and Kolab and Open-Xchange groupware servers.

Sync through Akonadi

KDE's Akonadi framework fetches, edits, creates and deletes events on remote services. The project recommends installing the kdepim-runtime package before starting the app.

Plasma clock widget integration

Events can appear in the calendar of Plasma's digital clock widget by enabling the PIM Events Plugin in the widget's settings and choosing which calendars to show.

Desktop and mobile layouts

The interface is designed for desktop, mobile and sizes in between, and the listing includes a mobile view. The project describes it as syncing across a Plasma desktop or phone.
