Switched from Calendly (too expensive) to "Appointment scheduling with Google Calendar" since I have Google Workspace and it was included. But that's super basic and missing a lot of functionality I was used to in Calendly. Luckily I was recommended TidyCal by a colleague and am loving it! I wish I'd discovered it sooner. For the price it's a no-brainer. And it works. And it looks great. What else could you ask for?
