CrowdSyncer

CrowdSyncer gives you real-time awareness of how many people are nearby, helps you discover live events, and keeps you connected with a privacy-first design.

Core Features • Live crowd count to see how many people are around you • Joined/Left trends to show how the crowd changes over time • Home screen widget for live count at a glance • No account required to get started • Privacy-first design with anonymous nearby counting

How It Works CrowdSyncer uses Bluetooth Low Energy to detect nearby phones that also have the app installed. Each device broadcasts a rotating anonymous identifier that changes regularly to reduce trackability. No personal profile is required, and location data is not used for nearby counting.

Privacy by Design • No account, email, or phone number required • No GPS location used for nearby counting • Rotating identifiers help protect privacy • Designed to minimize personal data collection

Optional Events Discover and join nearby events created by organizers. Get event updates and stay informed without creating a traditional account. Event features are optional, and you can leave an event at any time.
