TidyCal

TidyCal is low-key solving the most annoying workflow problem in the service economy — you shouldn't need three subscriptions just to book clients and get paid. The pitch is clean: create a booking page in under a minute, pull in Stripe or PayPal payments, and let it handle your calendar syncs across Google, Apple, and Microsoft without you lifting a finger, and honestly, that's exactly how it should work. Session bundles and packages are a smart addition that most basic scheduling tools skip over entirely, which tells me they actually talked to coaches and consultants rather than just building a feature list. If you're still invoicing via PDF and chasing Venmo requests, this is the move — the free tier exists and requires nothing upfront, so there's no real excuse not to at least test it.
