Mobile PDF toolkit apps

This cluster consists of all-in-one PDF toolkit apps for mobile devices, primarily iOS, offering a broad set of document tools such as editing, scanning, converting, signing, merging, splitting, compressing, and OCR. The dated entry timeline shows a single entry in April 2013, one in December 2019, one in April 2022, then four entries in 2025 (January, April, June) and three in early 2026 (January, March, May), indicating growing frequency in the months before the index start. Traction leaders, each with 0 stars, are PDF Toolbox - PDF Editor, PDF Export: Scan, Merge & Sign, and PDF Reader: Edit & Sign.

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.
