The British Red Cross wanted to develop a mobile phone app
offering people quick and practical first aid advice. We worked with the
British Red Cross and development team, 3 Sided Cube, to uncover how people would
use the app to apply simple first aid in an emergency.
first aid knowledge and advice at their finger tips
We conducted 2 rounds of research in the lab on Android, iOS
and Blackberry devices. Crucially there was a week gap between the 2 rounds of
research. This allowed the development team to refine the prototypes based on
During the lab sessions participants were asked to imagine
themselves in real life scenarios, where first aid would be required. This
approach allowed the team to see first hand how people would naturally use the
app. A significant portion of the audience were recruited to have little to no
first aid knowledge. We used a CPR mannequin to see how participants would use
the information in a practical situation.
We quickly delivered a design checklist and a list of
improvements, after each round of research. This ensured the team could quickly
respond to the feedback and implement rapid changes. Our final report contained
a list of outstanding issues and a list of success criteria.
The app has now been launched on the 3 mobile
platforms and has been very highly rated. It has been recommended in the
national press, and has an average rating of 4.5 stars on iTunes (from over
1800 ratings in less than 6 months). In the same time period the app has
received an average rating of 4.7/5 (over 600 reviews) on Google Play.
