From Concept to Success: How Lunárium grows thanks to Top-Quality UI/UX
How we helped our client increase sales, generate steady subscription revenue, strengthen company promotion, and prepare the business for international expansion by developing a cross-platform React Native app for activity planning based on the lunar calendar.
Requirements
Client’s wish
The client asked us to develop a mobile application with a subscription model. The main requirements were perfect usability (UX) and an engaging graphic design (UI) with intuitive controls. The lunar calendar helps users with optimal timing and planning of activities according to the moon’s cycles. The app can provide advice on nutrition, exercise, or important life decisions. Users align themselves with the lunar cycles and harness their influence on the human body and mind to achieve their goals.

Problem
Challenge for our developers
The biggest challenge for us was to accurately and meticulously translate the detailed UI/UX prototype from Figma into a stylish app that captivates with excellent design and is highly user-friendly. Additionally, we had to handle the integration of the subscription system through the App Store and Google Play, which is often a problematic process.
Solution
How we approached the project
When developing cross-platform mobile applications, we usually use the React Native framework, and this app was no exception. We created the design exactly according to the Figma prototype and tested it on several screen resolutions and devices to ensure the app looks and, most importantly, functions perfectly in every environment. For the subscription feature, we used libraries from the Expo SDK, which ensured a smooth development and testing process for this part of the app.
Benefits
System highlights
-
In-app Subscription Purchase: After registering, users can select a subscription plan within the app and pay using their preferred method. When the subscription expires, it can be easily renewed or changed in the same place. This gives users a clear overview of all their payments and provides the operator with a reliable and steady source of income.
-
Modern and User-Friendly Design: The app’s structure is based on carefully crafted UX design, so the layout of controls and feature design make perfect sense. The excellent user experience contributes to high customer retention and satisfaction.
-
Effective Promotion: The client can use our mobile app as an additional promotional channel alongside their Instagram account, centralizing their business activities. Furthermore, the app opens up future possibilities for expansion and adding new features.
-
Increased Sales: The lunar calendar in the app is linked to the concept of lunar bracelets. Customers who own the bracelet are now motivated to download the app, while those who only downloaded the app have an extra reason to purchase the bracelet. The app can also support the sale of other products in the client’s portfolio.
-
Potential for International Expansion: The app is already available on both Android and iOS. Now, by boosting promotion of the English version, the client can immediately reach an international audience and open new sales channels.
-
Personalized App Experience: Notifications sent to users are tailored based on their birth date and other personal data. Each user can use the lunar calendar to achieve different life and career goals. A diary for personal notes and wishes is also available.

Client’s reference
“We were looking for a reliable partner to develop our mobile application, which we had already designed and user-tested. Time and reasonable costs were very important to us, but above all, I expected smooth and, most importantly, human communication without unnecessary and complicated technical jargon. With Think Easy, everything went perfectly, for which I am extremely grateful. Not only do I consider them our partner for ongoing technical maintenance of the app, but I’m also happy to work with them on future projects where I need development support!”

Platform
Methods used for development
The design with the UI/UX prototype was prepared in Figma. For cross-platform app development, we used the React Native technology. Additionally, tools from the Expo suite were very helpful. We built the backend using Django Rest Framework with a REST API. The app was deployed to the production environment via Amazon Web Services.
