About Us
JHSV stands for Juri[1] Seelmann[3] and Vincent[4] Haupt[2]

The dynamic duo started developing websites in its early days. When we were 14 or 15 years old, we published our first professional website called “HÜ-Tausch” which was later known as “4school”. The purpose of 4school was to create a platform where pupils could share their homework with others and get rewarded with “4school points”. Although 4school did not get as famous as we hoped, we were thrilled when people from all over Europe started signing up on our website and even started uploading real homework!
Motivated from our early success we started lots of similar projects in the following years and created many private websites.
Some years ago, we began to develop mobile apps and again, like in our early days, we were very excited to see how many people liked them.

On this website you can see some of our projects.

Feel free to contact us if you have any questions.

We like to make Apps!

Hohoho ... 🎅 Christmas is coming soon. 🎄

To help you get away from the hustle and bustle of Christmas, this app will help making things easy for you!
With this app you can easily make a Secret Santa lottery to randomly choose who gives a present to whom.
This app can be used both while sitting comfortably with friends and family, as well as online via e-mail or various messengers.

Secret Santa is a Christmas tradition also known as Wichteln, Kris Kringle, Chris Kindle (Christkindl), Amigo Secreto, Monito-Monita, Angelito, Julklapp, or Engerl-Bengerl.

Especially in times like this, you don't necessarily have to meet in person, to make your yearly Secret-Santa drawing. Keep the social distance and also stay connected with your friends and family.
