Show HN: Planorio, a booking management system

Hello! For the last year I've been working on a side project, a booking management system. Among others, it allows anyone who owns a business that accepts bookings to manage them, to communicate with customers, to easily create a personalized website or to embed a calendar widget on any existing website.

There is still a long way to go, but I feel that now it is ready for some very direct feedback. :)

It mainly consists of an Angular frontend, a backend written in Node.js and some small tools written in PHP and Kotlin. I also created a hybrid mobile application in Ionic.

Thanks in advance to everyone who takes a look at it!
