Question 1

What is Rappn?

Accepted Answer

Rappn is Switzerland's leading independent grocery price comparison app. We compare offers from Migros, Coop, Denner, Aldi, Lidl, Aligro & Otto's — all in one place. 100% neutral with no retail partnerships: no supermarket pays us or influences our results. Build smart lists and find where every item costs less this week.

Question 2

Is Rappn really free? Are there any hidden costs?

Yes, Rappn is completely free and always will be. Saving on your shopping cart is everyone's right, not a luxury. We may introduce optional premium features in the future, but the core grocery comparison experience will remain free forever.

Question 3

Is Rappn independent from supermarkets?

Accepted Answer

Absolutely. Rappn has zero partnerships, sponsorships, or commercial agreements with any retailer. We are the only fully independent and neutral grocery comparison platform in Switzerland. No supermarket pays us, influences our rankings, or gets preferential treatment. Our only goal is to help you find the best deal.

In what languages is Rappn available?

Accepted Answer

Rappn is available in all four Swiss national languages — German, French, Italian, and English — serving every region of Switzerland.

Question 6

Which retailers does Rappn compare?

Accepted Answer

Rappn compares 7 major Swiss retailers: Migros, Coop, Aldi Suisse, Lidl Schweiz, Denner, Aligro, and Otto's. We aggregate 10,000+ live offers across all stores, updated daily. More retailers are being added continuously.

Accepted Answer

We update promotions and offers every day, across all 7 retailers. Our system processes weekly flyers, digital promotions, and official supermarket communications to keep you up-to-date in real time.

Question 8

Where does the pricing data come from? Are you truly independent?

Accepted Answer

All data comes from publicly available sources: official flyers, retailer websites, and promotional materials. We have no commercial relationship with any supermarket. Rappn is 100% independent and neutral — we don't sell products, accept payments from retailers, or let anyone influence our comparisons. Transparency is our core principle.

Question 9

How much can I realistically save with Rappn?

Accepted Answer

It depends on your budget and how much you use the app, but in general, by shopping smarter and more planned, it is possible to save around 30–35%, which is about one-third of your food budget.

Question 10

How do you calculate the estimate 'up to 2,000 CHF per year'?

Accepted Answer

The estimate is based on studies considering the average budget of a family, the percentage of savings achievable by regularly using promotions and discounts, and the fact that many recurring purchases can be shifted towards more convenient prices.

Question 11

How does the savings calculator on the website work?

Accepted Answer

The calculator takes your monthly grocery budget and estimates a potential saving of about 33% of that figure. It is an estimate based on studies and real behaviors of families who optimize their shopping by using offers and planning.

Question 12

Do I need to link loyalty cards (Cumulus, Supercard, etc.)?

Accepted Answer

No, Rappn works without linking any loyalty cards. This feature will be added in the future, but the app already delivers excellent savings without it.

Question 13

Does it make sense to use Rappn even if I always shop at the same store?

Accepted Answer

Absolutely. Even loyal Migros or Coop shoppers benefit from Rappn: instantly see the best current offers at your store, discover when to stock up, and learn if certain products are significantly cheaper at Aldi, Lidl, Denner, Aligro, or Otto's.

Question 14

Does Rappn also work for online shopping?

Accepted Answer

For now, Rappn is primarily designed for shopping in physical stores. Full support for online shopping will arrive in the future.

Question 15

How do shared carts / lists work?

Accepted Answer

You can share one of your carts with family, partner, or roommates. Everyone can see what needs to be bought, update what has already been taken, and add products and offers found through Rappn.

Question 16

Do I have to share my lists with other people?

Accepted Answer

No. You can create as many lists as you want and freely decide which ones to keep private and which ones to share. The control is always yours.

Question 17

How do I set up favorites and notifications?

Accepted Answer

Go to the Favorites section, choose a generic product (e.g., 'pasta', 'milk'), set the price range and supermarkets you want to follow. When Rappn finds an offer that meets your criteria, it sends you a notification.

Question 18

What does 'cheapest basket' mean?

Accepted Answer

It is the estimate of how much you could save on your basket by comparing the real active offers on the products you have entered. Rappn calculates the total cost if you buy everything in one store vs. taking advantage of the best offers across multiple supermarkets.

Question 19

Do I have to create an account to use Rappn?

Accepted Answer

You can see many offers even without an account. However, most advanced features (shared lists, favorites, smart notifications, savings history) require login.

Question 20

What personal data does Rappn collect?

We only collect the data necessary to improve your experience: information on the use of the app and the offers that interest you, and optionally your location to show you promos near you. The collection and processing of data follow Swiss privacy regulations.

Question 21

Do you use or sell my data to third parties?

Accepted Answer

No, we do not sell your data to third parties. Currently, we only use the data in an aggregated and anonymous form to improve Rappn, its features, and the quality of suggestions.

Question 22

Can I view, export, or delete my data?

Question 26

Why do I sometimes not see the same offers in the app as in the store?

Accepted Answer
