A spam blocker that shows its work.
Ringdocket is a phone-number block list with a public ledger behind it. Every number on the list is corroborated by three independent reports or by a public FTC complaint. When a campaign goes dark, we mark how it went dark. The point isn't a bigger list. The point is a list you can audit.

Fact sheet
- What it is. An iOS spam-call blocker plus a public web ledger. Free to block, paid to see the receipts.
- The differentiator. Every published number cites its evidence — user reports, FTC complaints, FCC enforcement — instead of a closed proprietary list.
- Numbers on the public ledger. 28,546+ corroborated phone numbers as of April 2026.
- FTC complaints ingested. 86,519 and growing daily.
- Active campaigns. 13 spam rings clustered, named, and tracked on the ledger today.
- Pricing. Free tier blocks calls forever. Ringdocket Full is $3.99/mo or $29.99/yr. Founding Flagger is $19.99/yr lifetime-locked, capped at the first 500 annual subscribers.
- Stack. SwiftUI on iOS, Astro + Cloudflare Pages on the web, Cloudflare Workers for the API and ingest crons, Supabase Postgres with row-level security on every table.
- What we don't do. No call recording. No contact-book uploads. No third-party tracking SDKs. No IDFA. See /security.
Quick angles
Three pitch lanes worth covering. Full versioning, quotes, and proof
points are in the brand messaging document —
docs/brand/04-messaging.md.
- "The spam economy has a public record now." Hiya, RoboKiller, and Truecaller block; none of them publish what they know. Ringdocket does.
- "Why your spam blocker won't tell you who called you." The business model behind closed lists, and what changes when the ledger is open.
- "Indie tools, real receipts." A solo-built product running on Cloudflare and Supabase, taking on a category dominated by carriers and venture-backed apps.
