Fintra - Budgeting App

Overview

Fintra is a budgeting app built for Gen-Z: people who want to understand their spending without ever opening a spreadsheet. The team needed a mobile UI system that felt calm, friendly, and fast to use every single day.

The Challenge

Most finance apps overwhelm new users with charts, jargon, and dense tables. Early research showed that people opened the app once, felt anxious about the numbers, and never came back. The goal was to make money feel manageable at a glance.

What I Did

I led UI design from first concept to developer handoff, working closely with two founders and a small engineering team.

• Ran a two-week discovery sprint with user interviews and competitor teardowns.

• Designed a mobile UI system with 60+ components, tokens, and light and dark themes.

• Crafted micro-interactions for adding expenses, hitting goals, and weekly recaps.

• Prototyped and tested the key flows with 12 users before development began.

• Delivered documented Figma files and supported engineering through launch.

The Result

The redesigned onboarding cut drop-off by 38%, and weekly active users grew 2.4× within three months of launch. The shared design system also reduced design-to-dev handoff time from days to hours.
