Shared Counter vs Synchronized Tally

Shared Counter is the simple and effective tool for counting visitors to events, local businesses, religious functions and much more, even with multiple entrances. To begin, create a new counter, optionally specifying the capacity. You can then share the counter with other devices, for example to monitor multiple entrances at the same time, via a simple link or QR code. You will always have under control the total count of all devices, synchronized in real time. The service was created in particular for monitoring access to the churches, but is now freely available. If you are in charge of a church you can access the "Reserved area for churches", to benefit from usage statistics and other useful services on the DinDonDan Web Services. Shared Counter is an open source project offered and maintained by the DinDonDan App association.

Whether you are tracking venue capacity, managing event check-ins, taking inventory, or keeping score, Tally keeps every device seamlessly in sync. Tap on one phone, and the count updates instantly across all connected screens. No accounts, no email logins, and no friction. Enter a room code, hand a device to your team, and start counting in under 30 seconds. Key Features: Instant Multi-Device Sync: Connect as many phones or tablets as you need using a simple share code. Every increment or decrement updates everywhere in real time. Flexible Counting Controls: Count up or down by single increments, jump in custom batch sizes, or make quick manual overrides on the fly. Zero Onboarding: Skip account creation entirely. Open the app, generate a code, and you are ready to go. Full Audit History: Review past sessions and timestamped tally logs whenever you need to verify numbers. Web & API Access: View tallies live on the web or integrate your counter directly into your own dashboards and workflows via API.
