Zeuler's main goal is to make the process of saving on grocery expenses easy and convenient, without requiring excessive efforts. With Zeuler, saving on groceries becomes a comfortable and personalized experience.

Expense analysis to mximize grocery savings


Zeuler operates with the aim of identifying potential savings on your grocery shopping list. This process is adaptable to every grocery expense and the type of products you intend to purchase. Zeuler assists you in determining whether combining purchases from different grocery stores in your area can lead to significant savings on your grocery list. Our primary mission is to guide you towards a more informed and conscious grocery shopping experience.

Step-by-Step guide to using Zeuler for groceries


  1. Entering Your Address: When you open the Zeuler app, start by entering your address or allowing it to geolocate you. This allows us to show you the available options at grocery stores within a 3 km radius of your location;

  2. Discover Available Grocery Products: Once you've provided your address, Zeuler will present you with the grocery products available from various stores in your area;

  3. Grocery Product Selection: When you select a grocery product, Zeuler automatically identifies the most affordable price among the available options;

  4. Grocery Store Choice: By adding a grocery product to your list, you are implicitly selecting a specific grocery store. It's important to note that once you do this, all grocery stores of the same chain will not be considered for future grocery products you add. For example if you add a product from sold by a Conad store, you will not see all the other products sold by other Conad stores in your area;

  5. Location-Based Optimization: Every time you add a grocery product from a new grocery store, Zeuler takes its location as a reference point. This is crucial to ensure that subsequent grocery products are chosen from grocery stores close to your last purchase location. In other words, Zeuler optimizes your grocery list based on your current location and the last selected grocery store, while always considering your starting location;

  6. Limitation to 3 Grocery Stores: Zeuler is designed with an understanding of consumer grocery shopping habits. Studies show that most people shop at a maximum of 3-4 grocery stores. Therefore, Zeuler limits the number of grocery stores considered for optimization to a maximum of three. This ensures that your grocery shopping experience remains practical and manageable.

You may have noticed that with every action you take, the algorithm tracks and recalculates its plans. For example, you may notice that the products displayed on the homepage are not the same every time you add an item to your list. This is because the algorithm is readjusting the availability of products based on the initially selected items and your current location.


In any case, Zeuler helps you with groceries: If you notice that the savings by shopping at different grocery stores are not significant, Zeuler will show you the cost of your grocery cart from each grocery store in your area, helping you make an informed decision. Remember that savings can vary depending on the contents of your grocery cart and the grocery products it contains. Additionally, it may happen that not all the grocery products you've selected are available at every grocery store; for example, a Carrefour brand grocery product may not be available at an Lidl grocery store. Zeuler will suggest a substitute, but you always have the option to modify it as you wish.

Zeuler's main goal is to put the power in your hands to decide how to optimize your grocery shopping list for maximum grocery savings. Whether you choose to buy groceries from a single grocery store or take advantage of the option to combine grocery purchases from different stores, Zeuler offers you an informed and tailored experience to meet your grocery needs.
