## Overview

LifeSync is a personal productivity and student-life application: users sign in, manage tasks and other life-planning areas, and can study financial-literacy lessons. The visible task workflow runs from the protected frontend task screen through its API client to the backend task route. Backend routes are mounted centrally; the sampled task route connects to its controller, while authentication and lesson completion show user identity and learning rewards. The README contains only the product name, so feature coverage comes from the source tree and frontend routes; unsampled domain internals are not expanded into speculative call chains.

Main entry points: [`lifesync/frontend/src/App.jsx`](https://github.com/mohitt-0805/lifesync/blob/main/lifesync/frontend/src/App.jsx) (Route composition), [`lifesync/backend/src/app.js`](https://github.com/mohitt-0805/lifesync/blob/main/lifesync/backend/src/app.js) (Express API), [`lifesync/backend/src/routes/authRoutes.js`](https://github.com/mohitt-0805/lifesync/blob/main/lifesync/backend/src/routes/authRoutes.js) (Auth routes), [`lifesync/frontend/src/features/tasks/Tasks.jsx`](https://github.com/mohitt-0805/lifesync/blob/main/lifesync/frontend/src/features/tasks/Tasks.jsx) (Task workspace)
