The free TidyCal does 99% of everything I need it to do. I would have purchased it even if I didn't need the additional features because it is such an easy to use, pleasant looking, and perfectly functional booking app, but I purchased it because I needed the multiple attendee booking feature. Regardless of the price - this is the best app of this kind I've ever seen/used, but it also happens to be the cheapest. TidyCal is what sold me on the whole AppSumo world of apps. Can you tell how happy I am with it? 🤗
