QR/barcode and 2FA apps

The dated entry history shows single entries scattered across isolated months from March 2020 to April 2026, with no discernible pattern of growth or clustering. The traction leaders, QR Code Reader＋Generator, ScanX:QR Code&Barcode Scanner, and QR. Barcode Scanner for iPhone, each have 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.
