The food allergen app your customers actually use
No downloads. No app store. Just a QR code.
Allergenius is a web-based food allergen app for UK restaurants, cafés and food businesses. Your customers scan, your allergen menu opens – every one of the 14 UK allergens, always up to date.
Why a no-download allergen app wins
The hard truth about traditional allergen apps is that almost nobody installs them. A hungry customer with a peanut allergy isn't going to download an app from an app store just to read your menu – they're going to ask a member of your staff or, worse, guess. Both create risk.
Allergenius takes a different approach. It's still a food allergen app – just one that lives at a web address and is reached by scanning a QR code. Every smartphone camera can do this with no setup. Adoption goes from a low single-digit percentage to effectively 100%.
Your customers get instant, accurate allergen information. Your staff stop being interrupted to read out ingredient lists. And your menu stays correct in real time – without a single app store update cycle.
What our food allergen app does
Built specifically for UK food businesses.
Zero downloads
Customers scan a QR code and your allergen menu opens in their browser. No App Store, no Play Store, no friction – the single biggest reason traditional allergen apps fail.
Works on any device
iPhone, Android, tablet, laptop – if it has a browser, your customers can read your allergen information. No operating-system support tickets, ever.
Live updates
Change an ingredient in the dashboard and every customer scanning the QR code from that moment sees the current version. No reprinting, no waiting on app reviews.
Filter by allergy
Guests select their allergens once and instantly see only the dishes that are safe for them – far better than scrolling through a static PDF.
UK-law focused
Built around the 14 UK allergens, Natasha's Law and the FSA's 2025 menu-guidance update. Not a generic global tool retro-fitted for the UK.
Shareable link, too
Every QR code is also a normal web link – paste it into your website, your booking confirmation email, or your Google Business profile.
"Allergen apps don't work" – and why this one does
"Customers won't download a new app"
Allergenius is not an app store download – it's a web-based food allergen app accessed by QR code or link. 100% of customers can open it. 0% need to install anything.
"Allergen apps look the same as everyone else's"
Add your logo and your menu is yours. The page customers land on after scanning feels like part of your venue, not a generic third-party platform.
"We change menus too often for an app"
Updates are instant. Whether you're a seasonal restaurant or a daily-rotating café, allergen information stays correct without any technical intervention.
