Online booking for your clients’ websites

Zytfenster is the booking tool for practices, therapists, coaches and the self-employed. You build it into their website, their clients book in three steps, and the data stays in Switzerland.

This is the real booking page of a sample practice, in German for now. Nothing is stored or sent, promise.

What Zytfenster does differently

Data protection and an admin area that’s a pleasure to use

Most booking tools are built for sales teams. Zytfenster is made for practices and self-employed professionals who handle sensitive data and have no time for complicated software.

Sectors

For anyone who works by appointment

Medical practices and dermatology

The patient uploads a photo before the appointment. Afterwards, it’s deleted.

Therapy and physiotherapy

First consultation and follow-up appointments, with a buffer between treatments.

Coaching

Video call, with the link right in the confirmation.

Beauty and hairdressing

Treatments of different lengths, with a reminder the day before.

Consulting and the self-employed

Requests instead of fixed bookings. You confirm, and the appointment is set.

Admin area

The admin area, as simple as the booking

All appointments at a glance, absences in two clicks, your own wording for every email. I’m happy to show it to you myself in a short video call.

For agencies

Built in with a plugin or two lines of code

Zytfenster runs on standard Swiss hosting with PHP, and there’s no database to set up. You bill your clients for the setup and support.

To be honest

Free means free. The catch is the support.

Zytfenster costs nothing, with all features and all updates, for as long as you like. What I can’t offer for free is my time. If you need help, you pay for it. That’s all there is to it.

When Zytfenster isn’t the right fit (yet)

  • Several people with their own calendars. A practice with three therapists currently needs three accounts. I’m working on it.
  • Payment when booking. Zytfenster takes appointments, not money.
  • Group classes with a fixed number of places. There are better tools for that.
  • French, Italian and English. On the way, but not here yet. For now, the app itself is in German only.
Pricing

Free, or I’ll do it for you

Zytfenster is free. You only pay for what takes work: installation, hosting with me and support.

Arto Steiner
Who’s behind Zytfenster

Hello, I’m Arto

My name is Arto Steiner, and I’ve been building websites for Swiss SMEs and self-employed professionals for many years. Zytfenster came about because a web designer was looking for a booking tool for her client: simple, with photo upload and with proper data protection. She couldn’t find one.

Zytfenster is a small product made by one person. If you write to me, I’ll answer you myself.

At walterlernt.ch I teach web design courses, at arto.ch you’ll find my work, and at kopfgerecht.ch I help people learn.
