How we developed a mobile app and saved thousands of dollars for the client

Client overview

Felmo is a German-based company in the field of veterinary services. The company provides a wide range of services including online consultations, appointment booking to the vet, instant and permanent access to treatment results, and more. The client wanted to develop a mobile app that connects vet clinics and pet owners looking for medical care services online.

In July 2021, felmo closed another major financing round following their successful Series A in February. This time they managed to raise €15 million! Burda Principal Investments led the financing round, including existing investors HV Capital, Redalpine, and 468 Capital.

Challenges

• The client wanted to develop a mobile application within 60 days on a limited budget. Hence, our task was to provide a solution that would allow us to quickly create a quality brand app and stay on the specified budget.
• The client's wireframes weren't enough to provide the user flow logic. They needed a UX audit and both UI/UX designs.
• The team had to deliver applications for iOS and Android platforms within 60 days.
  ‍

Scope of work

1. UX/UI Design development:

• Working with the client’s wireframes;
• UX audit;
• UI design. 

2. Mobile app development included:

• The development of a user interface for both versions of the app;
• Conducting market research to find a solution that would meet all the project's requirements;
• Continuous integration and delivery. 

Solution

Based on Eva Design System, the app enables users to:

• Keep track of the current appointments;
• Schedule the next appointment;
• Keep at hand a list of procedures prescribed by the vet;
• See each appointment in a vet clinic in detail (notes, time, etc.);
• Use the knowledge base via a series of articles;
• View a history log that includes the details of procedures and medicine prescribed by the doctor and their corresponding status;
• Communicate with vets via chats;
• Receive automatic notifications.
