## Description

"Fix Children Phone Using Time" is an Android app that helps parents control their children's phone usage. Set a specific time limit for phone use, and once the time is up, the app vibrates continuously to remind children to turn off the screen. If the screen is turned back on, the phone continues to vibrate, prompting children to return it to their parents. This innovative approach makes children uncomfortable, encouraging them to hand back the phone, ensuring responsible device usage.
