TidyCal is a scheduling tool built by the AppSumo team. You share a booking page, clients pick a slot based on your synced calendars, and the meeting lands in Google, Office 365, or Apple iCal.
It goes past basic scheduling: one-on-one, group, and recurring booking types, custom availability and buffer rules, paid bookings through Stripe or PayPal, packages, subscriptions, coupon codes, and reviews collected after each completed booking. It is aimed at online coaches, solopreneurs, and small businesses that want to stop paying a monthly scheduling fee.
The AppSumo deal is a one-time purchase with two plans. Individual ($29) gives 10 integrated calendars, basic integrations, and unlimited bookings. Agency ($79) adds Zoom and Teams, 4 team members, SMS reminders (U.S. & Canada), team pages, collective and round-robin meetings, and custom reply-to. The deal is only for people without an existing paid TidyCal account.
