Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Polizei Stressi is now free to download. New users can try every feature for one week; after that the calendar stays free and a one-time purchase unlocks the full version. If you already have the app, you keep everything. The Soli subscription has been discontinued. Also, hearings at the Kammergericht now show the correct location.
