## What is silentcrew(사일런트 크루)?

Achieve your goals with SilentCrew, the offline peer-to-peer accountability study timer.

SilentCrew is a productivity app that helps you focus together with people nearby, using local communication without needing internet or server connections. For those who can't help but check their smartphones when alone, it provides a loose sense of solidarity with people around you and a strong penalty system.

[Key Features]
- Offline Study Crew Matching: Automatically create rooms and connect with nearby users even in environments without internet.
- Accountability Penalty System: The moment you lose focus and open another app or go to the home screen during a study session, the screens of all connected crew members will flash red and an alarm will sound.
