CLUSTER CALLS-RULES-ANDROID · 12 ENTRIES · EARLIEST ENTRY 2021-07-20

Call & SMS blocking apps

This cluster comprises Android apps that block unwanted calls, SMS, and notifications using rules, allowlists, crowdsourced databases, and regex filters. Entries appear sporadically from June 2019 to July 2026, with no clear trend before the index start. The traction leaders are NotiFilter, SpamBlocker Extended (Call/SMS/Notification), and SpamBlocker (Call & SMS), each with 0 stars on the activity signal.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
