Attendance estimates and insights for events and open spaces.
Most attendance estimates rely on:
Visual Counts
Manual Methods
Small Samples of Devices
The result is numbers that are often difficult to explain or defend.
The Solution
Tally™ by Datafy is a simple device (all you need is power) that provides:
Estimates Across Any Footprint
Measure attendance at single-location events or across complex, multi-site environments — with confidence.
Minute-by-Minute Attendance Estimates
Understand how activity builds, peaks, and changes throughout the event.
Foot Traffic Insights
See how people move through a space and how long they stay.
Complete Event Data
When paired with our big data analytics suite, Tally can provide a holistic and robust snapshot of your event’s performance.
How It Works
Tally is a smart proximity sensor designed to determine the number of devices and people within a ~250-foot radius, with privacy built into its foundation.
It's easy
Our team will help you determine how many Tally devices you need and where to place them to capture real-world presence from nearby smart device signals.
Tally does not collect personally identifiable information (PII) and cannot be used to trace individuals- so no worries on privacy compliance.
Your Tally can be installed permanently or be used as a roamer at your event.
Tally will feed estimates into your Datafy dashboard to generate accurate crowd size estimate.
Paired with your other Datafy insights you can get the full picture of what happened and export easy reports.
