Built a daily budget tracker that reframes monthly money management around a simple daily allowance, automatically recalculating based on unspent days and recurring costs.

Launched with category-based spending limits shown as live progress bars, time-bound recurring expenses (for short loans, trials, and installments), and an automatic new-month rollover that carries unspent savings forward or offers a fresh start.

Conducted four user interviews after the initial build, which directly shaped a second development phase: inline category creation, a redesigned UI with dark mode, restructured navigation, and a two-phase onboarding flow.

Delivered as a fully functional, publicly accessible web app, tested end-to-end before moving on to the next app in the challenge.
