Budget App: from scattered spending to clear weekly control
Problem
Users were tracking expenses in notes and chats, which made category totals and weekly limits hard to trust.
Solution
I designed a focused budgeting flow with fast entry, category structure, and sorting so people can review spending in seconds.
Impact
The app made day-to-day money decisions easier, with clearer visibility on where money goes and quicker end-of-week reviews.
