Phone privacy and call protection apps
Cluster of mobile apps addressing phone privacy and call management, including spam/scam blocking, caller ID lookup, number masking, and second number services. Dated entries span 2012 to January 2026, with a single entry in 2012, a small group in 2015–2016, sparse singles in 2021 and 2024, and three entries in late 2025 plus one in January 2026. Traction leaders by activity signal are Burner: Second Phone Number, Sanket, and Xlines, each with 0 stars.
Entry timeline
ENTRY TIMELINE
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.
