CLUSTER MOBILE-SIGNATURES-PDF · 64 ENTRIES · EARLIEST ENTRY 2024-10-06
PDF signing and e-signature apps
This cluster consists of mobile, web, and desktop apps focused on signing, filling, annotating, and sharing PDF documents, often with reusable signatures, stamps, and scanning capabilities. Dated entries begin in 2011-10 and remain sparse (one per year or less) through 2023, then become more frequent from 2024-09 onward, with the highest monthly counts in 2025-07, 2025-08, and 2026-02. The traction leaders, all with 0 stars, are SignOB: Fill & Signature PDF, Expert Sign: eSign PDF Docs, and Signer: Electronic Signature.
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.
