( Overview )

Ledgerline had a loyal user base but a leaky funnel: almost half of new sign-ups never funded their account. I led a redesign of onboarding and the everyday money screens, working from research through to launch.

( The challenge )

( Approach )
  1. 01

    Value before paperwork

    Reordered onboarding so people could explore a live, personalised preview before verifying their identity.

  2. 02

    One number that matters

    Introduced a ‘safe to spend’ figure on the home screen, backed by clear, editable assumptions.

  3. 03

    A system to scale

    Built a token-based design system shared across iOS and Android, cutting UI build time by a third.

( Results )
