Never again do you need to search through calendars and arrange appointments, because now GNU will do it for you!!! Entirely automatically and in just a few seconds, whether it’s for 2 people or 200.
come GNUgether!

It takes time to find a suitable date. GNU checks all the dates when everyone is available, and finds suitable times in an instant. For busy or enterprising people and team workers. For managers, clubs and everyone who simply likes getting together.

Choose a period in which you’d like the meeting to take place. Send an invitation to the desired participants. GNU automatically compares your suggestion with the calendars of all the participants, and shows you possible times you have in common (GNU is familiar with all the current smartphone system calendars). The possible dates appear on your smartphone again in an instant. You confirm the date, GNU sets the meeting up and enters it in its own calendar.

Would you like to know
how much TIME and MONEY
you can GAIN with GNU?

Time is money, especially when it comes to making appointments. And in everyday life we aren’t even aware of how much time we actually spend making appointments. Based on survey results, GNU has established that it takes around seven and a half minutes to make an appointment, and that around 80% of this time can be saved by using the GNU app. GNU has used this knowledge to develop this calculation tool, which will show you the huge potential that lies in coordinating your appointments this way. Simply complete the fields below and click on the red calculation button.

How GNU Works


Give your meeting a name, a short description and a location. Add participants from your list of contacts. Finally, set the duration of your meeting and the timeframe during which you want to hold the meeting.


A single click sends your GNU request to all selected participants, who will be notified via a Push notification. As soon as you have given the “okay”, GNU will scan participants’ calendars and check which times are possible.


The potential times found by the app will be displayed on your smartphone screen. You are now free to decide which time suits you best and confirm your selection on the app.


Once all participants have agreed to your desired time, GNU will send notification of the final arrangement and mark it on participants’ calendars.

What People Say About GNU

As a board member, I’m often required to organize meetings that require the attendance of all invitees. This used to be a fairly laborious affair, with lots of back and forth and tens of phone calls. GNU saves me time and frustration.

- Max Gescheider, AUSTRIA

I also like to use GNU for non-business meetings. I recently organized a school reunion – we settled on a date in super-fast time and were soon together again for the first time 18 years!

- Tobias Lungötzer, GERMANY

Coordinating meetings is what I do – and it’s a daily challenge. I’ve been waiting a long time for an app that makes it easier. Since I’ve been using GNU, 90% of my meetings have been arranged solely via smartphone.
