I originally got this product through my Plus membership back in 2022. Because it is positioned as a Calendly alternative, I wanted to compare the two solutions. That comparison link is at the bottom of this review.
The short version: for the AppSumo audience, TidyCal is hard to beat. It covers the core use cases, booking pages, paid appointments via Stripe and PayPal, unlimited booking types, Google Calendar sync, automated reminders, and intake forms, without a monthly bill attached to it. Setup is fast and the interface is frictionless.
The one gap worth knowing before you buy: there is no mobile app. If you manage your schedule from your phone throughout the day, that creates real friction. It is not a dealbreaker for everyone, but it is the most consistent complaint and you should know it going in.
For most solo operators, freelancers, and small service businesses, TidyCal is likely everything you need long-term. Where Calendly earns its subscription pricing is team scheduling, CRM integrations like Salesforce and HubSpot, advanced routing logic, and enterprise compliance requirements. That is not the AppSumo buyer.
