About Rappn
Save more. Shop smarter.
Rappn is the Swiss grocery intelligence platform that helps households take back control of their weekly shop. Built in Zug, engineered for Switzerland, designed for every canton and every language the country speaks.
Our Mission
Grocery prices in Switzerland are among the highest in the world, and the information needed to shop well is fragmented across dozens of flyers, websites, and apps. We believe price transparency should not be a luxury — or a full-time job.
Our mission is to turn complex promotional data into clear, actionable savings: which store has the best basket this week, which offers are genuinely worth it, which products match your diet and your habits.
One app. Four languages. Every canton.
What Rappn Does
Six ways Rappn puts the Swiss weekly shop back in your hands.
Aggregates weekly offers
Weekly promotions from Migros, Coop, Denner, Aldi Suisse, Lidl Schweiz and others — structured, searchable, comparable.
Works canton by canton
The offers you see reflect the prices that actually apply in the canton where you live.
Speaks four languages
German, French, Italian and English — so Rappn fits the country instead of forcing the country to fit the app.
Plan your weekly shop
Favourites, saved offers, shopping lists and shared household carts for the people you live with.
Respects how you eat
Dietary attributes such as vegetarian, vegan, organic and high-protein when the underlying data allows.
Alerts that matter
Personalised notifications designed to save you money, not to interrupt your day.
Independent by Design
Rappn is independent. No supermarket chain owns us, controls us, or influences how we rank offers in our core comparison views.
We do not sell groceries
We help you buy them more intelligently — we are a comparison platform, not a retailer.
We rank offers honestly
When we display sponsored content, we label it clearly and visibly — because Swiss law requires it and our users deserve it.
We do not sell your data
Your cart, your favourites, and your shopping habits are yours. We do not sell them to retailers, brands or data brokers.
Privacy, the Swiss Way
Rappn is built on the revised Swiss Federal Act on Data Protection (revFADP / nFADP) and applies GDPR-grade practices as a baseline for every feature we ship. We collect only the data we need to make the product work, we explain what we do with it in plain language, and we give you straightforward controls over your information.
For any data protection question, including access, correction, and deletion requests, write to us at info@rappn.ch.
Who We Are
Rappn was founded by engineers and operators who were tired of overpaying for essentials — and tired of how much time it takes to shop well in a country where the same yogurt can cost very different amounts three streets apart.
