Google Calendar

Calendly, Acuity Scheduling, Setmore, Square Appointments, and SimplyBook.me stand out as the most popular and widely used appointment scheduling tools, based on market share data, review volume, expert roundups, and user adoption across sources.

These tools help eliminate email back-and-forth by letting clients book directly from your calendar availability, with features like automated reminders, payments, team scheduling, and integrations (e.g., Google Calendar, Outlook, Zoom, CRMs). Popularity varies by use case—general meetings vs. service businesses (salons, clinics, consultants) with payments or custom workflows.
