Designing and building a mobile app for surgeons

Project Type
Mobile App
React native


Conformis develops and manufactures custom knee and hip joint replacements. They wanted an app that enabled surgeons to access pre-operative plans (iViews) for their upcoming hip or knee cases, as well as expose other surgeons to Conformis content. The Gnar Company was hired to design and build the iViewer mobile app for Conformis.

Design and Discovery

The Conformis team and The Gnar Company kicked off the work with a Design and Discovery project to define the user personas, user journey, and key app features. The discovery workshop was followed by designing the mobile app screens and creating a click-through demo consistent with the Conformis brand.


The Gnar integrated the mobile app with Conformis's internal ordering platform for authentication and access to surgical iViews.

Mobile App

The Gnar Company built the Conformis iViewer with React Native and launched in the Apple App Store optimized for both phone and tablet. The app enables Conformis surgeons to review knee and hip iViews anywhere, access Conformis surgical technique videos, contact their local sales rep or Conformis customer service, and send invitations to colleagues to download the app. Non-Conformis surgeons can create an account to access sample iViews and other Conformis content, as well as contact their local sales rep to learn more.
