Would you use a biometric app to track your physical reactions while watching a movie?
Launched in October 2026, the free ScareScore app utilizes smartwatch sensors to record audience physical reactions in real time. The software synchronizes biometric data with specific onscreen events by listening to the film soundtrack.
Why it matters
The platform replaces traditional subjective exit polls by providing filmmakers with objective, data-driven reaction curves. This technology allows creators to quantify the physical impact of intense spatial sound experiences and horror sequences.
The platform is currently available as a free application on Apple WatchOS and Android WearOS. It debuted for public use during October 2026 festival screenings.
