CalenGoo vs One 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

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

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.

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.

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.
