Open the app and you can begin the Einbürgerungstest practice straight away — it is free. For the DTZ features, enter your name and email to start a 7-day free trial with full access — no charge during the trial.
The Einbürgerungstest ("Leben in Deutschland") is a free multiple-choice test with 33 questions (17 correct to pass). The DTZ (Deutsch-Test für Zuwanderer) is a language exam with four skills (Hören, Lesen, Schreiben, Sprechen); DTZ practice is the paid part of the app.
The Einbürgerungstest practice is free. To unlock full DTZ access you can make a one-time Lifetime purchase, or a 1-month or 3-month pass. These are one-time purchases and do not auto-renew. On iOS they are handled securely through your Apple ID (App Store). Manage or view purchases in Settings → Apple ID → Purchase history on your device.
In the app, open the paywall and tap "Restore purchases". Make sure you're signed in with the same Apple ID you bought it with. If anything is missing, email us and we'll sort it out.
App Store purchases are refunded by Apple. Request one at reportaproblem.apple.com. If you have trouble, contact us and we'll help.
