Teach the lesson. The room answers back.
An iPad presents your slides and hosts the questions. Students join from whatever phone is already in their pocket.
Put your own deck on the projector and mark it up as you talk. Drop questions between the pages and the room answers from their phones — then the reasoning goes up too, so the class can argue about it. That argument is the lesson; the scoring is only what keeps everyone in it.
At the end every student saves the whole thing: your slides, your handwriting on them, and every question with its answer.
Nothing to install
Students scan a code or type a short link. No app, no accounts, no passwords — so it works on whatever hardware a class already has in its pockets.
No internet required
The iPad is the server. A local network is enough. Halqa reaches the internet in one place only — when you install an activity from a link — and nothing about a student is stored anywhere.
Your slides, your activities
Send a PDF and it becomes a lecture you can present and draw on. Or describe an activity to an AI assistant connected to your iPad and it builds it onto the device.
See how it works — seven panels, about a minute.
Ready-made activities
16 finished activities for mathematics, physics, chemistry, biology, geography, history, language and computing — plus two built for staff workshops. Free to download, and once one is on the iPad you can rewrite it with your own AI assistant — swap the questions, change the subject, add a round.
