Good start

It works fine, has a intuitive interface and good logic behind. I’m not a programmer, so I can’t comment about the quality of coding, but so far so good – no conflicts or errors. Many features are under development as I can see in your roadmap, but please reevaluate priorities since some important points are “in discussion” (like recurring appointments, buffer time, user dashboard and profile…) In my opinion these are more important than niche solutions, for example)

Overall this is a very promising solution! Waiting also for SaaS version!
