## Overview

This is an Android to-do app whose visible capabilities include task entry and detail, calendar browsing, completed-task review, statistics, and task notifications. The tree also shows separate repositories, DAOs, models, and a database helper, suggesting a persistence layer beneath the screens. Source excerpts and README documentation were not provided, so the connections between screens, data layers, and notification scheduling cannot be verified; those uncertain calls are intentionally not drawn.

Main entry points: [`app/src/main/java/com/example/todolist/activities/MainActivity.java`](https://github.com/hptho-gitlab/personal-schedule-management-app/blob/master/app/src/main/java/com/example/todolist/activities/MainActivity.java) (Task list)
