CLUSTER CALL-CALLING-NUMBER · 3 ENTRIES · EARLIEST ENTRY 2012-04-01

Second phone number apps

This cluster consists of mobile and business apps that provide users a second phone number for calling, texting, and privacy, often with spam blocking, call recording, or AI-assisted handling. The dated history is too thin to read a shape from—only three entries predate the index, so the cluster's timeline cannot be characterized. Traction leaders are Allo: AI Second Business Phone, iPlum: Business Phone Number, and Burner: Second Phone Number, each with 0 stars.

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.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 3 listed below. Unlabelled means nothing has decided yet — not that the answer is small.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
