CLUSTER MORSE-CODE-TRAINER · 4 ENTRIES · EARLIEST ENTRY 2026-09-29

Morse code training apps

This cluster consists of Morse code trainer applications, each focusing on different aspects: browser-based practice with decoding, hardware-connected paddle training, and progressive lessons leading to speed certification. The dated history is too thin to read a shape from, as there are no dated entries before the index start. Traction is uniformly low, with all members showing 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.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 4 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.
