LehrPuls puts your question to the whole room — and shows you within twenty seconds who is keeping up. Participants answer on their smartphones, the result appears on the projector, and you decide whether to move on or take another run at it. Everything runs on your own laptop: no account, no cloud, no subscription.
The devices connect straight to your computer via QR code. No outside service is contacted — LehrPuls also works without internet access.
Neither you nor the participants create an account. Answers stay in the room and in your local database. That settles the GDPR conversation.
Your questions stay. Every session is analyzed, and across the years you can see whether the same question fares better next semester.
Drag questions from your own pool into a playlist. Created once, reusable every semester.
QR code on the projector, point the camera at it. No download, no sign-up — joined in under 30 seconds.
Space bar opens, space bar closes, R shows the solution. Without taking your eyes off the audience.
Distribution, difficulty, discrimination and response times — per question, permanently archived.
FourteenEleven question types: multiple choice with one or several correct answers · open question · poll with one or several votes · numeric answer with tolerance and unit · estimate · ordering · matching · fill-in-the-gaps · scale · word cloud · image question · info notice

There is no provider reading along, because nobody stands in the data path. For name lists you set a deletion period; LehrPuls reminds you and removes the names at the press of a button, while the analyses remain, anonymized. A sample privacy notice ships with the application.
