Safe self-diagnosis

The challenge

This focus of this project was to develop a product to help consumers make better decisions regarding the treatment of respiratory diseases and offer peace of mind. It can be quite expensive and time consuming for consumers to see the doctor over what usually turns out to be an OTC treatable condition.

How can we create a product that effectively helps consumers to make better decisions that can save time and money?


Phase 1

The project was kick-started with a design workshop to understand the basic brief and formulate a plan of action. Working in collaboration with an international company we started the discovery process with some product research based on existing apps in a related market (self help medical apps). I put together a rough mood board based on the types interaction, ui trends and functionality that may be required. For example, onboarding, colour pallets, iconography, iOS based visual formats, user control types, personalisation, etc.. 

Research and collaboration

The target market for the consumer was based in South America so we worked in collaboration with our partner, sharing insights on demographic details.

We put together a range of personas based on the demographic most likely to benefit from a self-diagnosing app of this type. The developed on to a set of consumer journey diagrams for two persona types, 1 – the acute sufferer and 2 – the chronic sufferer

Early wireframes and prototypes

I worked primarily in Sketch ( collaboration in Sketch Cloud )  to build a modest picture of the self-diagnosing app.

This went through a significant number of iterations with feedback from all stakeholders to ensure we were on the right track. From low fidelity wireframes to high fidelity concept screens.

The end of phase 1 was complete.

We had an MVC working demo with sufficient functionality to meet the brief so the next step was usability testing.


The general feedback showed we had to understand the target audience much better in many areas. Whether feedback is good or bad it’s still feedback – which is essential to improving your product and understanding what went wrong and how to resolve issues.


Please note: All digital design work produced by me was done as an employee of ResApp Health Limited.

Insightful feedback points to implement in phase 2

  • Reducing wordiness – making sure the app sounds less technical
  • Changing the language to more informal / friendly
  • Ways to improve credibility:
    -Explain performance of app
    -List medical conditions tested by ResApp, reasons for things.
    -Give some kind of an ‘okay’ response for healthy people testing out the app
    -Show the user more information at the results stage. The initial ’See the doctor Immediately’ message was a bad experience for users who would much rather know more detailed info to help them make decisions on next course of action.
    -list out possible conditions within the ResApp diagnosis
    -Include CTA  “learn more about managing the common cold and allergic rhinitis”
  • Refactor the UI by showing a meter which has 4 levels from ‘no symptoms’ to ‘speak to dr immediately’
  • Potential for advertising messages while results are processing.
  • Rebuild questions to be more intuitive.
    Instead of ‘do you have a fever? YES/NO’ have a subsequent question to find out the temp
