Cuddle Lock Stroller

Rental Mobile App

Project Description

The Cuddle Locks mobile application was designed to facilitate the rental, management, and return of commercial strollers. Users can easily rent a stroller by scanning a QR code and end their rental using NFC technology. The app provides real-time data updates and remote monitoring capabilities for administrators, ensuring efficient management of stroller fleets.

Our Role

Verttx played a crucial role in transforming Cuddle Cart's vision into a fully functional mobile application. We conducted detailed discussions to understand their needs, designed and developed an intuitive user interface, and integrated NFC and QR code technologies for seamless rental and return processes. We also ensured robust data security, conducted extensive testing, managed the app’s deployment, and provided ongoing support and maintenance.



  • Develop user-friendly iOS and Android applications that facilitate the rental, management, and return of commercial strollers.

  • Integrate QR code scanning and NFC technology for easy rental initiation and return processes.

  • Ensure the application is secure and capable of handling real-time data updates and remote monitoring.


  • Ensuring cross-platform compatibility and seamless performance across a range of devices and operating systems.

  • Integrating NFC technology and QR code functionality to provide a smooth and reliable user experience.

  • Creating an intuitive interface that simplifies the rental process for users while offering robust management tools for administrators.

  • Ensuring data security and privacy due to the sensitive nature of user information and transactional data.


Our Development Process

Product Scope

We focused on the business vision and created a comprehensive brief for the project by gathering all the research on the market, competitor benchmarks and any other necessary information. Then we met with the client in an immersive session to craft a value proposition and set the main assumptions to prove. Finally, we created the ultimate list of user stories and features necessary to prove those main assumptions within the MVP.

Clickable Prototype

We developed a non-functional prototype to simulate user interaction. The experience of using the clickable prototype was very much like the final product itself, this was the adequate phase to test the information architecture, the UX and most importantly to present all involved counterparts a concrete outcome.

Product Rationale and Tech Scope

After an immersive session with all the stakeholders, we had all the information we needed to create the ultimate list of User Stories and features necessary to prove the main assumptions in a Proof of Concept (POC). Our experts in Product, UX/UI and Tech Architecture focused on finding the answers to all of the questions raised throughout the scope preparation. On the tech side we elaborated a memorandum tackling our suggested approaches for tech stack selection, database technology and orchestration. Together with Bocconi University and AlixPartners we started defining the useful datasets and the algorithm behind the lending decisions.

Full Development

With the decisions closed in the previous steps, we went on developing the product through agile cycles.  


Once the product went live we started to gather end-user feedback and improve the product. New iterations were made in parallel with new features so that the end-user has the best experience possible.







"The Cuddle Locks app has transformed our stroller rental operations, making it easier for our customers to rent and return strollers. Verttx's expertise and commitment to quality were evident throughout the development process, and we are extremely satisfied with the outcome."
