Speaks your guests' language
Weddings and parties bring people together from everywhere. Koestr meets each guest in their own language: the join screen, the challenges, the buttons and the prompts all switch automatically, and anyone can pick their language in a tap.
What you get
Why hosts love it

English, French, Dutch, German and Spanish — each guest sees Koestr in theirs.
Automatic, then adjustable
It follows each phone's language, and any guest can switch with one tap.
Your wall, localised too
The big screen and the host dashboard speak the same languages.
