Customers Don't Need to Download Anything - That's the Point
Every additional step between a customer wanting to see your menu and actually seeing it costs you some percentage of people who give up along the way. An app download is one of the biggest steps you can add.
Nobody wants a new app for a single visit
Asking a first-time customer to download an app just to see a menu is a big ask for a relationship that might be one visit. Most people simply won't do it, and you never find out how many orders that cost you.
A QR scan is a step people already know
Scanning a code with a phone camera is now a familiar action for most people - no new behavior to learn, no app store detour, no account creation before they've even seen what you serve.
Works the same for every customer, every device
An app has to be built and maintained separately for different phone platforms. A web-based digital menu works the same way in any phone's browser, with nothing to install and nothing that goes out of date on someone's device.
Lower barrier means more people actually look
The easier it is to see your menu, the more people actually do - browsing before they've even decided to sit down, which a locked-away app or a hard-to-read printed board doesn't achieve nearly as well.
Simple, on purpose
The lack of an app isn't a missing feature - it's the reason a QR menu removes friction instead of adding it.
