Personalizing a lunch ordering service for mobile
Food Revolution is a food delivery service offering a weekly subscription for premium lunches, delivered to homes in the Budapest area. To further improve their service, an AI-powered mobile application is in development. As of September 2025, the mobile app has yet to be launched.
Goal
To place orders on mobile while providing extra features.
Customers can also order their food on the website, but their engagement should be increased through offers by collecting points and using AI to customize their basket.
The company may be known from the popular TV show "Cápák között" (the Hungarian version of "Shark Tank"). The project was a collaboration between Konstruktor Online and OS.labs.
Problem statement
The website is not personalized.
Also, textual display is not beneficial.
The service targets wealthy, middle-aged, single sports enthusiasts who are mindful of their diet. Therefore, information about the ingredients is important to them, but at the same time, they prefer not to spend too much time putting the orders together.
Design system
From the existing branding, I created the design system for the mobile application.
High-fidelity wireframes and flows
The mobile application of Food Revolution should be user-centric, but business needs must also be considered.
I had just 65 hours to deliver the UX/UI design (including the design system).
When selecting food from the menu, users can choose different portion sizes (regular or large), variations (gluten-free or sugar-free) and extras (toppings, side dishes, etc.). They can also view macro values, ingredients and allergy information.
If enabled, the AI automatically adds food to the basket based on preferences. When users first start using the app, this feature is inactive, as it needs to learn their tastes by allowing them to select their favorite items during the first few orders. For example, if they consistently choose meat-free options, the AI will infer that they likely follow a vegan lifestyle and will start recommending vegan foods in the future.
Users can earn points by making orders. These points can be exchanged for Forints and redeemed. There are rewards available on levels. Points expire after a certain period of time if no orders are placed and users might be dropped to lower levels.
They can also maintain a balance, allowing them to pre-load money for future use.
In the settings, they can enable notifications and manage personal data.

Impact overview
Food Revolution can continue to grow with the mobile application.
With a monthly revenue of 60 million Hungarian Forints (as of January 2024), the company was already on a growth path, but the addition of this new channel will further boost it. The new features are likely to attract new customers while loyal ones will appreciate the innovation, especially if they are already satisfied with the quality of the food.
