How we grade them
| 3.2GPAVimcalVery good | 3.8GPAWorld Time BuddyExcellent | |
|---|---|---|
| Value for money | C$25 a month billed yearly ($300), or $35 monthly. A typical calendar app starts around $6, and the dear ones around $10. The assistant edition, Vimcal EA, is $68.75. Their terms say payments are non-refundable unless agreed in writing. | AThe website costs nothing. The only price anywhere is a $2.99 upgrade inside the iPhone app, for location groups, and the maker's own mobile page gives a workaround that unlocks it for free. |
| Free plan and trial | BThe iPhone app is free, with drag-and-copy availability, time zone conversion and duplicate merging. But desktop apps, booking links and polls are all paid. There's a free trial of the paid plan with no card needed. | AFree with every feature on the web since the maker dropped paid subscriptions in May 2022. The iPhone and Android apps are free downloads too. Most people will never pay a thing. |
| Features | ADrag-to-share availability, unlimited booking links, polls, overlapping working hours across time zones and a keyboard shortcut for every action. Google and Outlook show in one view with duplicates merged. It only works with those two, though. | BIt does one job, comparing time zones, and does it fully: hour tiles, daylight saving warnings a week ahead, a Google Calendar overlay and widgets for your own website. But it won't hold your events, and the App Store shows the last iPhone version as November 2020. |
| Ease of use | A4.7 from about 470 App Store ratings. Vimcal advertises response times under 100 ms, and you can use it straight in the browser without installing anything. | A4.8 from about 14,000 App Store ratings. Add your cities, drag across the hours you want, send them to your calendar. That's the whole thing. |
| Platforms and integrations | BWeb, Mac, Windows and iPhone, with Zoom, Google Meet and Microsoft Teams built in on top of Google Calendar and Outlook. But the site lists no Android app, so half the phones out there are left out. | AWeb, iPhone and Android, and a time you pick opens in Google Calendar, Outlook, iCal or Gmail. Do note Google Play labels the Android app as having ads, and shows its last update as January 2020. |
| Best for | people whose week is wall-to-wall meetings | comparing time zones at a glance |
