A cooperative bank with three hundred thousand members, fourteen notification styles, and three typefaces. We kept the members and lost most of the rest.

Too many voices

Lumen had a carousel that nobody swiped, a loyalty programme nobody could explain, and a home screen that changed every quarter without getting clearer. The app was trying to sound like a startup while holding people’s savings.

Quiet by default

We cut the home screen from eleven modules to four, rebuilt the transaction list around merchants instead of codes, and gave every alert one job and one tone. The navigation went from five items to three.

Designing for trust

Money apps do not need delight. They need certainty. We tested copy with members over sixty, simplified transfers to two steps, and made every confirmation readable at a glance. The result is boring in the best way.

Six months after launch, completed transfers were up twenty-two percent and searches for how do I questions fell by half.
