01 / The brief
A banking app people opened once a month, to check a balance and leave.
Halvard had 420,000 customers and an app built around account numbers. Payments, savings and cards each lived in a separate tab with its own rules.
The brief was one sentence: make the app the place where customers decide what to do with their money, not only where they look at it.
02 / The approach
We rebuilt the home screen around the next decision, not the last transaction.
Twelve interviews showed that people think in goals and bills. I mapped every flow to one of those two ideas and removed the rest from the first screen.
A coded prototype went to 300 customers in week six. We changed the transfer flow three times before a single final screen was drawn.
03 / The outcome
Weekly active use rose 31% in the first quarter after launch.
Transfers now take two taps from the home screen. Support tickets about finding a feature fell by 44%.
The savings goal feature, which did not exist in the brief, now holds $38M in customer deposits.
