Calendly is a scheduling app founded in 2013 by Tope Awotona and based in Atlanta.
Users connect their calendar and set the hours they are free. They share a booking link, and others pick a time that fits both sides, with no back and forth emails. Calendly adds the meeting to both calendars and sends reminders. It handles time zones, buffers between meetings, video links for Zoom, Teams and Google Meet, and round robin booking for teams.
The free plan covers one event type. Paid plans add more event types, integrations and team features.
