TidyCal

I’m genuinely surprised by how aggressively TidyCal pushes its own branding — even with a premium account. On mobile, the “powered by” branding feels like the main call to action, which is a pretty frustrating experience when you’re trying to offer a professional booking flow. Even most free tools keep branding more subtle than this.

At the very least, premium users should have the option to disable or tone it down. Until then, it’s hard to recommend TidyCal for anyone client-facing.
