Cake cutting! 🎂
One app for every kind of get-together
How it works
From QR code to live wall in minutes
Create your event
Pick from 12 templates, tweak the challenges and colours, and print your QR sign. Two minutes, no design skills.
Guests scan & play
No app, no account. They scan, add their name, and start capturing photo & video challenges from their own phones.
Moments go live
Approved captures land on the big-screen wall in real time — and everything's saved to your private gallery.
Everything you need
A whole photo booth, in everyone's pocket
The screen everyone can't stop watching
Put Koestr on the big screen and the room lights up — new moments drop in as they're captured, hearts tick up live, and the party sees itself unfold in real time.
In your guests' hands
Challenges, moments & bragging rights
Guests get a home base, a deck of challenges, a live gallery and a leaderboard to fight over — all from one QR scan, no download.
Occasions
A template for every celebration

FAQ
Good questions, answered
Do my guests need to download an app?×
No. They scan the QR, type their name, and they're in — it runs right in the browser on any phone, iPhone or Android.
What happens to the photos and videos?×
Everything is saved to your private host gallery in full quality. Approved moments also appear on the live wall, and you can download the whole album as a ZIP whenever you like.
Can I control what shows up on the screen?×
Yes. Choose to auto-approve, or review everything first — and hide or spotlight any moment. Uploads are AI-screened before they can reach the wall.
Is it private?×
Guests see a clear consent screen when they join, you control who can view and download, and nothing is ever public unless you choose to make it so.
What do I need for the live wall?×
Any screen with a browser — a TV, a projector or a laptop. Open the wall link and it fills up in real time as guests capture.
How much does it cost?×
Start completely free. Paid plans are per event, so you only pay when you're actually celebrating — no subscriptions.
