The Problem

Spam call volume is up 300% since 2020. Carrier-level blocking is slow, opaque, and misses numbers that have been reported by hundreds of real users.

How We Built It

Community-sourced blocklist that propagates reports to all users in real time. Mobile-first UX that integrates with native call handling APIs.

The Result

Live at ringdocket.com. Growing a community database of reported numbers across both platforms.
