Who each one suits

Dato

  • Mac users who want their schedule one click away in the menu bar
  • People who keep missing the start of video meetings
  • Anyone working across time zones who wants several clocks in view
  • Buyers who want a one-time purchase and no subscription

World Time Buddy

  • Picking a call time for people in different countries
  • Showing a webinar time in each website visitor's local time

Worth knowing

Dato

  • Mac only. The current version requires macOS 26 or later; older macOS releases get older versions of the app.
  • The vendor calls it a read-only view of your events: it can create events, but editing one or answering an invitation opens Apple's Calendar app.
  • It has no sync of its own. Google, Outlook and other accounts must first be added to the built-in Calendar app.
  • Natural-language entry is not supported yet, and the menus and settings are in English only.

World Time Buddy

  • Renaming locations and grouping them in tabs on the website require signing in.
  • The iOS app lists a $2.99 in-app upgrade, although the maker's mobile page gives a workaround that unlocks it free of charge.
  • The App Store shows iOS version 1.28 from November 2020, and Google Play shows the Android app last updated in January 2020.
  • Google Play labels the Android app as containing ads and in-app purchases.

Key features

Dato

Menu bar calendar and event list
A month calendar with optional week numbers and event indicators sits above a list of upcoming events and reminders. How many days and events it shows is adjustable.
Fullscreen meeting notifications
A notification fills the screen when an event starts. It can be limited to video calls, events with an alert or accepted events, and paused with a Focus Filter.
Join video calls
Join the next call from a notification, the event details or a global keyboard shortcut. Zoom, Google Meet, Microsoft Teams and more than 50 other services are recognized, and others can be added.
World clocks and time travel
Clocks for several time zones appear in the Dato menu or the menu bar, with custom names and offline search of 15,000 cities. A slider shows what time it will be elsewhere.
Upcoming event in the menu bar
The next event can be shown as its own menu bar item, next to a date and time display whose format, icon and color can be customized.
Shortcuts, widgets and quick entry
A global keyboard shortcut opens the new event window, which can also create reminders. Shortcuts actions switch calendars and notifications on or off, and widgets show the date, calendar and world clocks.

World Time Buddy

Hour-tile time comparison
Add locations by searching for places or time zones such as UTC, reorder them by dragging and mark one as home. Each location gets a row of hour tiles aligned with the others.
Select and share a time range
Click and drag across the hour tiles to pick a range, then open it in Outlook, iCal, Google Calendar or Gmail, copy it to the clipboard, or create a public event page.
Google Calendar overlay
Signed-in users can overlay Google Calendar above the hour tiles to find open slots. The mobile apps can show the device's calendars in the same position.
DST warnings and weekend marking
Daylight saving warnings appear a week before a change. Weekends are highlighted, including in countries where the weekend is not Saturday and Sunday.
12-hour, 24-hour or mixed format
Hours can be shown in 12-hour or 24-hour format, or in a mixed mode that uses each location's native format.
Embeddable widgets
A world clock widget and an event widget can be placed on a website. Both detect each visitor's time zone, and the event widget shows the event in the visitor's local time.
