Shared Counter

Shared Counter is a simple and effective Chrome extension designed to manage visitor flow for events, local businesses, religious functions, and more. It allows creating counters with optional capacity limits, which can be shared across multiple devices via links or QR codes. This feature is perfect for monitoring multiple entrances simultaneously, ensuring a synchronized, real-time total count across all devices.

Originally developed to support church access monitoring, Shared Counter now serves a broader audience. Church managers can access a reserved area offering useful statistics and additional services via DinDonDan Web Services. As an open-source project maintained by the DinDonDan App association, Shared Counter emphasizes transparency, community collaboration, and ease of use.
