This version was shut down

This version was in service for 1533 days (or more than 4 years) and served 678002 tests for 921009 visitors.

It is not possible to maintain two versions as the successor of this version is already online on

This version stayed online for some time to prevent recent results from becoming invalidated. Now, after half an year I think is time to finally pull the plug.

I want to give a big thank you to the contributors. Without your help this project would not be possible!

The new version of is available in 11 languages and includes an simplified expierience and improved decision making.

Thank you for making this project a success story!
