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.


  • 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 a specified budget.
  • The client's wireframes weren't enough to provide the user flow logic. They needed a UX audit and UI/UX designs.
  • The team had to deliver applications for both 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. 


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.

Technology stack

The outcome of the project is a multifunctional mobile application with a set of custom icons and illustrations. 

  • A ready-made UI Kit based on the customer’s style guide and Eva Design System.
