Propagator worked with sleep experts, ResMed, to redesign a new mobile app (iOS, Android and Apple Watch), improve usability, create a more compelling user experience and ownable identity.

The Challenge

ResMed is a developer, manufacturer and distributor of medical equipment for treating, diagnosing, and managing sleep-disordered breathing and other respiratory disorders.

ResMed were looking to expand into the direct to consumer market with a new sleep application and hardware device to help ordinary people with sleep disorders to improve their sleep and so feel better during the day.

Propagator were asked to help redesign their new mobile app in iOS and Android. The challenge was how to do this with very limited time before their planned launch in the US.

The Solution

Propagator worked in an agile manner to design a completely new user experience, including new user flows, and visual design that focused on first time and repeated use, iconograpy, wallpapers and data presentation to help users engage with this exciting new product.

Propagator then designed an Apple Watch solution to complement the app.


Sales of the hardware and the associated app are growing, as ResMed establishes awareness of the product. The S+ app and associated Apple Watch version featured in Apple’s official launch as part of the HealthKit examples.
