I really like Tidycal for a number of reasons: the superb pricing, and the neat design. Also I was happily surprised by all the settings that where available, such as private link, redirect to your own URL, and the very smooth way you can add integrations such as payments and online meetings.

Overall I am very happy. The only thing I would like to be improved is the way the booking calendar behaves on mobile phone. For customers who wants to book, there's a lot of scrolling going on and I would like the calendar to be full width.
