## Overview

Saldo Mensual is a Spanish-language personal-finance web app for managing monthly cash flow. The user enters through the React app, completes setup or signs in, then works with transactions and recurring expenses and reviews financial summaries. Budget envelopes, alerts, profile/settings, and goals are additional product areas visible in the supplied excerpts or app structure. Most behavior lives in one large App.tsx; the graph separates its domain responsibilities without implying separate modules. Firebase calls and the React entry point are evidenced; other internal feature wiring is not detailed in the excerpts.

Main entry points: [`saldo-mensual/src/App.tsx`](https://github.com/karlosmontoya91/app-de-control-de-gastos/blob/main/saldo-mensual/src/App.tsx) (Finance workspace), [`saldo-mensual/src/main.tsx`](https://github.com/karlosmontoya91/app-de-control-de-gastos/blob/main/saldo-mensual/src/main.tsx) (React entry)
