Koalendar vs TidyCal

Koalendar

• Solo professionals and teachers who want unlimited free bookings
• Small businesses that take payment when a client books
• Booking rooms or other shared resources alongside people

TidyCal

• Solo coaches, consultants and tutors who would rather pay once than monthly
• Selling paid sessions, packages and subscriptions from a booking page
• Small teams that want round robin on a flat-priced plan

Koalendar

• The Free plan syncs 2 calendars, offers only Google Meet for video links and has no reminders, payments, group sessions or custom form questions.
• Koalendar is testing new pricing: some new visitors are shown Pro at $9 per seat / month on annual billing ($12 monthly) with an added Business or Premium tier.
• A seat is any bookable user or resource, so rooms and equipment count toward the bill. SMS reminders cost extra.
• HIPAA support with a BAA is sold as an add-on on request.

TidyCal

• The Free plan connects 1 calendar and cannot auto-create Zoom, Google Meet or Teams links; those need a paid plan.
• Free and lifetime plans pay TidyCal a 1% platform fee on Stripe payments, on top of Stripe's own fees. Only Pro has none.
• Lifetime plans are bought through AppSumo, and Agency Lifetime licenses bought from September 1, 2026 are capped at 4 team seats.
• There is no iOS or Android app; TidyCal runs in a browser. The Pro subscription has no free trial.
