This is what practising looks like.
Screens from the app: the dashboard, one task from each module, and the feedback you get back.

Why PrepDaF works when textbooks don't
You don't fail on German. You fail on the format.
Knowing the grammar isn't enough if the clock, the task type and the marking scheme surprise you. Practise the exact format until nothing does.
Writing and speaking need a marker, not an answer key.
Multiple choice grades itself. A Brief or a Sprechen task doesn't. AI feedback gives you a score and the specific fixes, every time you submit.
A plan that counts down with you.
Your study calendar works back from exam day. Miss a session and it reshuffles. No guilt, no starting over.
One place, every module.
No more juggling PDFs, audio files and a separate flashcard app. Every skill the exam tests lives in one dashboard.

What learners say
“Writing was the part I kept putting off. The feedback helped me see where my argument was unclear and which sentences needed work. Having something specific to fix made it much easier to sit down and try again.”“I study after work, so most evenings I only have half an hour. It helps to have the exercises in one place instead of spending that time deciding which book to open. I've managed to stick with it more consistently this way.”“Recording myself felt awkward at first. But practising with a timer made me realise how much time I spent trying to find the perfect word. I'm getting better at keeping going, even when I make a mistake.”“Mostly using it for Lesen and Sprachbausteine. It's useful to work through a task and then go back over what I got wrong. I'd still like a dedicated app for the commute, but the browser version does the job.”“I use German every day, but writing an exam answer is a different thing. The practice showed me that I needed to spend more time on sentence structure. That gave my studying a bit more direction.”“The writing feedback is what I keep coming back for. I used to check an answer, think 'okay, makes sense' and move on. Now I actually rewrite it. Takes longer, but I feel like I'm learning more from each task.”Founding prices
