AreaCode Tracker

Cluster spam calls by carrier area code so blocking actually works

Problem

Users complain that carriers themselves are the biggest source of spam: calls and texts arrive in pairs, and blocking one number just makes the sender switch area codes — block 10016 and next comes 02010016. Number-by-number blocklists are useless against rotation; people need to recognize 'this is the same crew.'

Solution

A lightweight guard that logs incoming calls and SMS with number, area code and contact matching, clusters spam by origin, detects one organization rotating numbers, and supports one-tap bulk blocking or exporting a complaint list. Optionally augments matches with public spam number feeds.

Users

Everyday Android users harassed by carrier, loan and insurance calls, plus anyone who wants to file bulk complaints.

MVP

Read call log and SMS and cluster locally; tag suspicious origins by area code and prefix; detect number rotation from the same source; one-tap bulk block or export a complaint list; read-only permissions with data never leaving the device.

Revenue

Free basic clustering with a one-time unlock for bulk complaint export and custom rules; or affiliate referrals to call-blocking apps.

Why now

Spam has shifted from random numbers to organized area-code rotation that defeats manual blocking, and carriers will never build a tool that exposes their own sources — a perfect indie gap.
