Hargreaves Lansdown

HL's new mobile

financial app

Big Radical

Mobile is an important pillar of the Hargreaves Lansdown service and digital strategy. After experiencing rapidly increasing mobile traffic (eclipsing that of the use of the desktop PC) the brief was to rebuild the dated HL Live app from the ground up, using the latest standards of design, architecture and technology.

Testing was crucial throughout this development cycle. We demoed all stages of design and non-functional prototypes during user testing sessions right through to the last phases of completion of the app. Customer responses were positive throughout, however their insight often differed from common assumptions.

Using the customer feedback through the development process helped us avoid wrong turns and wasted effort. The final stage of user testing was a month-long beta test with the ‘finished’ app. Again, a crucial stage to ensure no show-stopping issues emerged.
