CLUSTER FRIENDS-BETWEEN-EMOJI · 6 ENTRIES · EARLIEST ENTRY 2022-07-24

Puzzle-encoded messaging apps

This cluster consists of apps that turn text into puzzles, ciphers, or visual riddles for playful private communication between friends, from barcode-style pranks to emoji decoding. Dated entries show an early 2022 burst (two in March, one in July) and a later pair in July and December 2025, though the overall sample is tiny. Traction leaders (cursus_publicus, Custom Riddle Generator, VibeBites) all have zero stars, so no product has yet gained a clear follower base.

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 6 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.
