CLUSTER DOCUMENTS-SIGNATURES-IOS · 19 ENTRIES · EARLIEST ENTRY 2023-03-29

Mobile PDF e-signature apps

This cluster comprises mobile apps, predominantly for iOS, that enable users to sign, fill, edit, and share PDFs (and sometimes Word) using electronic signatures, stamps, and initials. The dated entry history spans August 2017 to July 2026, with a noticeable gap between 2017 and 2021, followed by sporadic entries that slightly concentrate in late 2025. The traction leaders by activity signal are Signature Maker - Sign Creator, PDF Sign - Signature App, and eSign - PDF Signature & Docs, all of which currently show zero 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.
