Pinbook vs When2meet
When2meet makes everyone fill a grid.
Pinbook reads the calendars.
When2meet is a free, no-frills classic: you create a grid, send the link, and everyone drags to mark when they’re free. It works — but it’s entirely manual, and the availability people enter is a guess, not their real calendar. Pinbook reads each attendee’s actual calendar and surfaces the first time they’re all genuinely free.
The core difference
With When2meet, every attendee re-enters availability by hand on a heatmap, and you then eyeball the darkest column to choose a time. Nothing connects to a real calendar, so a “free” block can be wrong the moment someone’s calendar changes.
Pinbook removes the grid entirely. Each attendee connects a calendar once (no account), Pinbook scans real free/busy across Google, Outlook, Apple, Yahoo and Fastmail, finds the first slot everyone is free, and then creates the event and sends the invites.
