I built a personal budget app with React Native here's what I learned

The starting point: a problem I lived myself Like many people, I had tried every budget app on the market. They were either too complex, too rigid, or simply not adapted to the way I think about money. The trigger was a simple observation: there's no single right way to manage your budget.
