Termin-Kalender: The Smart Alternative for Small Teams & Clubs

Appointments & Team Organization – without the chaos.
The smart alternative for small teams, clubs, and freelancers. Forget bloated project management tools or rigid event-ticketing plugins! Termin-Kalender combines an intuitive, beautiful calendar with simple team tools (To-Dos, Messages).
No “empty screen” on your first start thanks to our clever assistant, no steep learning curve. Just install, display your appointments, and be productive right away!

🎯 Why “Termin-Kalender”? (The end of plugin chaos)

Stop managing separate calendar, task list, and reservation or any form plugins — because form submissions from Termin-Kalender’s own forms flow straight into your To-Do list and calendar. We built Termin-Kalender to give small workgroups exactly what they need: A perfect schedule overview blended with lightweight team communication.

✨ The Highlights (Free Version)

Effortless Smart Setup: Describe your business, club, or project in detail — the better you describe what you do, the more accurately our clever assistant tailors your color-coded categories and setup recommendations. No endless setup, no empty calendar on your first run!
Looks Fantastic Everywhere: Show the full calendar or a compact list of upcoming appointments on your website. Insert your events via Gutenberg, Widget, or Shortcode – they adapt seamlessly to most themes.
NEW & Free – Display Any External Calendar (iCal & Google): Already using Google Calendar, iCloud, or Outlook? Simply paste the iCal (.ics) link to display your calendar or any external calendar directly on your website — even as a clean appointment list! (Another plugin saved!)

🚀 Termin-Kalender PRO (For professional teamwork)

Internal Tasks & To-Dos: Keep your To-Dos in a simple list that is easily shared. To-Dos with dates show up directly in your calendar. Appointment requests from forms are added straight to your To-Dos AND your calendar!
Team Messages: Easily set up teams and a frontend app for discussions and team meetings. Includes a reminder function for all popular messengers.
Flexible Bookings & Contact Forms: Create booking, reservation, or general inquiry forms. Dated requests appear directly in your calendar (confirming an entry blocks the slot against double bookings), while general inquiries go straight to your To-Do list.
Absolute Theme Freedom: The engine creates standard Gutenberg posts that are perfectly and beautifully designed. Publish events as real blog posts, without being trapped in rigid calendar layouts.
Edit from Anywhere: Allow team members to manage the calendar directly from the frontend without logging into the WordPress backend.
Live iCal Feed & Backend Google Sync: Let your team or clients subscribe to your Termin-Kalender schedule in Google Calendar, Apple Calendar, or Outlook. Plus: Sync private Google events directly into your backend calendar for a unified overview.

*PRO features require an upgrade.
