CLUSTER MOBILE-TEXT-CODES · 8 ENTRIES · EARLIEST ENTRY 2025-02-03

Encryption and secure sharing apps

This cluster comprises apps for end-to-end encrypted sharing of files, text, and secrets, often using QR codes, passphrases, or PGP, with a focus on offline and on-device security. The dated history shows an isolated entry in September 2013, a long pause, then regular entries from February 2025 through July 2026, with the most activity in early 2026. Traction leaders all show zero stars, so no product stands out in activity.

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.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 8 listed below. Unlabelled means nothing has decided yet — not that the answer is small.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
