A notice:
We switched the app model to freemium (free + in-app purchases), but unfortunately we had to upload a completely new app to do this. This app has been unpublished. This means that only users who have previously purchased the app can find and install this app.

So what does this mean for you?
You can continue to use this app as usual and download it again at any time. If you would prefer to use the new app (link below this section), you are welcome to do so. (As of October 2023, the content is the same) In order to unlock all content in the new app, this app must be installed. (The new app checks every time it starts whether the old one is installed.)

▶Information cards
We provide detailed information cards for most questions, which you can view after you have answered them. Especially for the knowledge test, it is crucial that you not only memorize questions, but also really understand them. With these information cards you get the chance to learn effectively.

▶Exam simulation
Choose between three different modes: the original mode with 72 questions or the more compact modes with 36 or 18 questions. In all modes the ratio of questions is identical to the original. After each simulated exam you will receive a detailed evaluation.

▶Intelligent query
If questions have been answered correctly three times, they will only be displayed again after 6 hours. From the 4th time onwards only after the user-defined number of days.

▶Light and dark mode
Choose the mode that suits you.

▶Optimized navigation
Among other things, a large button at the bottom for the main interaction in the question view. Furthermore, the box in the answer options does not have to be checked exactly; just tapping on the answer is enough.

▶Cloud sync
Optionally, you can synchronize your progress with the Internet and use the app on different devices. (also cross-platform iOS/Android)

▶Detailed statistics
Check carefully which chapter you may still need to work on.

▶Individual question filter
Here you can decide whether you want to see the questions in a specific order or mixed together. You can also choose whether you only want to display incorrectly answered questions or difficult questions (answered correctly less than 3 times). In the settings you can specify when correct questions should be reloaded.


With our app you are well prepared for the §34a expertise test and the security industry. Use it as an effective tool for your IHK exam preparation and master the challenges of the security industry.
