We're now set up and running with TinyCal and we're really happy with it so far. We came over from Calendly, which whilst did nothing wrong, was maybe overkill for what we needed.

The setup was a bit clunky at times and it took me a while to get my head around what settings I needed to set things up how we wanted them, but the customer support (shout out to Luka!) was absolutely fantastic. He talked me through every question and gave me exact instructions where I needed them and I can't praise him highly enough. Thanks Luka and I'm looking forward to using the app.
