I've been using TidyCal for a while now, and honestly, it's one of those purchases I'm really happy I made.

It already had everything I needed from the start, but what I appreciate most is that the team keeps improving it. New features are added regularly, and they're actually useful (not just features for the sake of adding more features).

If you're looking for a scheduling tool that's simple, dependable, and keeps getting better, I'd definitely recommend giving TidyCal a try.
