Phone-first software in daily use

QR App, our product for restaurants and hotels, is used on phones every day by guests and owners. It runs in the phone’s browser, so there is nothing to install.

Guest menu

A menu guests use on their own phones

Guests scan a QR code and the menu opens straight away, with search, filters, categories and an English and Hindi switch.

  • Designed for one hand on a small screen
  • Search, filters and categories
  • Works on any iPhone or Android

Got questions?

Questions we hear a lot

Yes. Most apps are built once with React Native or Flutter and run on both. When an app needs it, we build natively with Swift for iPhone and Kotlin for Android.
