When? (when.direct) is a social scheduling tool: you share one link, each person connects a calendar, and the overlap appears. WhenMeet.me solves the same group-time problem — connected Google and Microsoft calendars are read live as Free/Busy and everyone else paints their free time by hand — and then goes on to booking: it writes the event to the host’s calendar, and also offers personal and team booking links with reminder emails. Facts about When? come from its own homepage, read on 17 October 2026.
| Feature | WhenMeet.me | When? (when.direct) |
|---|---|---|
| Group availability | One shared heat-map of every participant’s availability, with ranked best slots | Overlapping free time shown as people connect their calendars |
| Calendars supported | Google + Microsoft live; public iCloud feed read-only; other calendars via hand-marked availability | Google Calendar, Microsoft Outlook, Apple iCloud and CalDAV calendars, per its homepage |
| Account | Host signs in with Google or Microsoft; guests need no account | Its homepage says no account or signup is required |
| Someone without a connected calendar | Paints free time on a two-week grid at /free and confirms by email, no account needed | Not described on its homepage |
| Calendar data read | Availability only: event titles and bodies are not stored or shown to anyone | Free/busy only, per its homepage |
| Booking links | Personal link ready the first time you open Booking links after connecting a calendar; more link types on one page | Not described on its homepage |
| Team links | Everyone must be free, or round-robin to whoever is free, each in their own hours | Not described on its homepage |
| Reminder emails | Emails 24 h and 1 h before by default (15 min to 2 days, or off); no SMS | Not described on its homepage |
| CRM, Slack and webhooks | HubSpot, Pipedrive, Slack and signed webhooks (Zapier, Make, n8n) | Not described on its homepage |
Both tools start from the same idea: instead of a poll where everyone types availability, read the calendars. When? asks each person to open the shared link and connect a calendar. WhenMeet.me does that too — anyone with a connected Google or Microsoft calendar appears automatically — and keeps a hand-marked grid for the people who will not connect one, so a group isn’t blocked just because someone won’t connect a calendar. Confirming a time writes the event to the host’s calendar and emails ICS invites.
When? describes itself as a group tool and its homepage does not list booking links, team links, reminders or integrations. WhenMeet.me also covers the one-to-one side: connect a calendar and open Booking links, and a personal booking link is live with default settings, team links route a booking to whoever is free, reminder emails go out before the meeting, and bookings can sync to HubSpot, Pipedrive, Slack or a signed webhook.
If every person in your group uses Apple iCloud or another CalDAV calendar and you want them to connect it directly, When? says it supports those, while WhenMeet.me reads only a public iCloud feed and relies on hand-marked availability for other calendars. And if you want to avoid creating a separate account, When? says none is required — people just connect a calendar; WhenMeet.me needs the host to sign in with Google or Microsoft.
WhenMeet.me is the better fit when you need real cross-provider Free/Busy matching without polls, where guests need no account, or a personal booking link that is ready the first time you open Booking links after connecting your calendar. A meeting can include up to 50 participants.
When? (when.direct) can be a better fit if your team is already standardised on it or if you need features it offers that WhenMeet.me does not.
Both overlay calendar free/busy to find a time for a group. WhenMeet.me adds hand-marked availability for people who do not connect a calendar, writes the confirmed event to the host’s calendar, and offers booking links, team links, reminder emails and HubSpot, Pipedrive, Slack and webhook sync. When? says it needs no account and supports iCloud and CalDAV calendars.
No. Anyone with a connected Google or Microsoft calendar appears automatically; others paint their free time at /free and confirm by email, no account needed.
Google and Microsoft calendars live, plus a public iCloud calendar feed (read-only). Anything else is covered by hand-marked availability. When? says it works with Google Calendar, Outlook, Apple iCloud and CalDAV calendars.
WhenMeet.me works from availability, not event details: titles and bodies are not stored or shown to anyone. For a public iCloud calendar feed the full file is fetched temporarily and only dates and busy status are used. When? also says it reads free/busy status only.
When your group is on iCloud or CalDAV calendars you want connected directly, or when you want no separate account for the organizer. WhenMeet.me needs the host to sign in with Google or Microsoft.
