About this app

Lappen Lock brings together two things that usually work against each other: your phone and your theory test.

You choose the apps that distract you the most. When you try to open one, a question from the official question bank appears first. Answer correctly, and your phone is unlocked. This way, you study precisely in the moments when you'd normally just be scrolling.

THE BLOCKER

• PIN protection to prevent you from accidentally unlocking yourself in a moment of weakness

ACCESSIBILITY SERVICE API
Lappen Lock uses the Android Accessibility Service to detect when you open a locked app—this is the only way the block can take effect immediately, and you'll be shown a theory question instead. Only the package name of the currently opened app is read; screen and window content are not accessed. This information remains entirely on your device and is neither stored, transmitted, nor shared. The service serves the core app blocker function, not disability support, and is only activated after you grant permission within the app.

ALSO

• App interface in ten languages: German, English, Arabic, French, Italian, Polish, Romanian, Russian, Turkish, Ukrainian (the exam questions themselves are in German)

• No account, no registration

• No ads, no tracking, no analytics

• Your learning progress stays on your device

SUBSCRIPTION
Lappen Lock is a paid app. You can see the current price in the Play Store and in the app before purchasing. The subscription renews automatically and can be canceled at any time in your Play Store subscriptions.

NOTE
Lappen Lock is a private learning tool and is not affiliated with any testing center or authority. The questions are taken from the official question catalog; you take the exam yourself at the responsible authority.
