TidyCal

Was originally using Session for booking, but all of a sudden they lost their momentum, so Tidycal was in my mind already because they have been here for a while.

Solid solution, even some complain about lack of break time, but there is already and it's called Add unavailable dates, so yeah, not much more to ask.

It's impossible to find a Zoom alternative because they are the best by far.

All I was asking for was a booking link like this and to have it already send lead notifications to my WhatsApp so super reliable.
