G6 Application Simulation


The biggest challenge faced, was having the ability to showcase the apps functionality, without pairing to a glucose monitoring device. Dexcom found themselves finding it very difficult to provide users, doctors, and clients with the experience they got on the actual app. Without showcasing that experience, the benefit the app provided to these cohorts was being lost.

This problem stemmed from the previous version of the app, the G5. However, the solution was to have a separate app, which showed a series of screenshots. This gave Dexcom’s audience a snapshot of the functionality and abilities of the app, however, the interactive experience of the app, and indeed the benefit of the app, was still lacking. The G6. Interactivity, functionality, and experience, laid the foundation for Achieve’s team when building the new app. We wanted Dexcom’s customers and users, to see more than just screenshots. We wanted them to become immersed in the experience the app gives, and how it provides a complete efficiency when managing their diabetes.


Uncovering the needs of Dexcom’s consumers highlighted the solution Achieve must provide. Experience was at the heart. We needed to build an app that allowed the users to forsee how it will streamline the management of their diabetes. How it eliminates complications, and how it further minimizes the stress of dealing with diabetes on a day to day basis.


Combining our own ideas for the simulator app, with surveys from Dexcom’s marketing and sales teams allowed us to make informed decisions on the functions and features of the app.

We wanted to teach users how to get the most out of their device. We built a reactive simulator app that was more than just screenshots. It contained a number of sections, with the most pertinent being: Simulation.


The purpose of this section was to show a simulation of how the real app works. To do this, the user pressed “play” and the screen begins to demonstrate what occurs when the real app is put to use. This included: hitting ranges, giving alerts, and also allows for users to test out different settings within the simulation. Remaining focused on the user experience, guided us in building this important section of the app.


In addition to creating the different interactive sections, Achieve’s developers were tasked with changing the framework of the app. The previous version of the simulation app was made in two code bases, Android and iOS. For the newer version, we used a react native framework so that the app was made in one code base and then built to both app stores. This improved the efficiency of updates greatly.


The previous version of this app, the G5, did not capture the experience and benefit for the user. A series of screenshots highlighted no more than the aesthetics of the app, leaving it up to a verbal explanation to convince users of the apps power. The focus of the build on the G6 however was to provide this experience to the user. We aimed for users to become immersed, and to recognize the benefit the app will pay in their daily lives.
