Purpose of the App:

The app aims to help users reduce their phone usage time through tuning and mutual guarantee.

How It Works:
The user selects a time window during which they wish to refrain from using their phone and invites someone close to join them in this commitment.
During that period, the user activates the app and sets the phone aside for the chosen duration. The app will remain active while the phone is unlocked, the screen will turn black, brightness will be reduced, and the time window will be displayed.
Once the user completes their chosen time, they will also see the time windows of their friends who participated in the same session.

Features:
1. The app can be used individually, without inviting friends.
2. To invite friends, they must first be added through the friends screen, and the friends must approve the connection.
3. Reflection on past sessions is available as an option.
