TidyCal

TidyCal is a simple, affordable online scheduling tool from AppSumo that lets you create booking pages so people can schedule time with you without back-and-forth emails. You set your availability, share a link, and clients or colleagues pick an open slot that syncs to your calendar. Positioned as a budget-friendly alternative to pricier scheduling apps, TidyCal is best known for its one-time lifetime deal — pay once and keep access — which makes it especially popular with solopreneurs, freelancers, and small businesses watching recurring costs.

The platform covers the essentials of booking. Multiple booking-page types handle one-on-one meetings, group bookings, and paid sessions; calendar connections (Google, Outlook, iCloud) show real availability and prevent double-booking; and you can collect payments (via Stripe/PayPal) for paid appointments, add buffers, set date ranges, and send reminders. TidyCal supports embedding, custom questions, and integrations, focusing on doing straightforward scheduling well at a low price rather than offering enterprise-grade complexity.

TidyCal serves solopreneurs, freelancers, coaches, and small businesses that want cheap, no-fuss scheduling. It offers a Free plan (limited, around 10 bookings and one calendar connection), a Pro subscription around $12/month (or about $99/year) with more calendars and features, and — its signature — one-time lifetime deals via AppSumo (Individual Lifetime around $29, Agency Lifetime around $79). It competes with Calendly, Acuity Scheduling, SavvyCal, and Doodle, differentiating on very low cost and a pay-once lifetime option.
