A whole photo booth, in everyone's pocket

Koestr is a live event photo game — playful challenges, a big-screen wall and a private gallery, all from one QR scan. Here's everything it can do.

Live wall

A big-screen mosaic that fills with your guests' moments in real time — on any TV, projector or laptop.

A gamified deck of prompts keeps everyone shooting the good stuff, with points and a friendly leaderboard.

Points, streaks and a live leaderboard turn capturing moments into friendly competition.

Drop a challenge at exactly the right moment — “cake cutting!” — and watch it pop up on every phone at once.

Reach every guest's phone in a tap — announce a moment, launch a challenge, or tell them the photos are ready.

Approve, hide or spotlight before anything hits the screen. Uploads are AI-screened for safety first.

Guests join by scanning a QR and typing their name — it just works in the browser, on any phone.

Browse by challenge or contributor, favourite the best, and download the whole album as a ZIP.

Guests heart the moments they love, and the counts tick up live on the wall for a bit of buzz.

The whole guest experience in five languages — English, French, Dutch, German and Spanish — chosen per person.

Clear consent at join, host-controlled visibility and downloads. Nothing is public unless you choose.

Shot in a dead corner? Captures queue up and upload the instant signal returns. Nothing is lost.

Set up your event in two minutes and see for yourself. It's free to start.
