CLUSTER ACROSS-CATEGORIES-CONVERTS-2 · 7 ENTRIES · EARLIEST ENTRY 2021-05-03

Offline measurement & currency converters

This cluster comprises mobile apps that convert measurements and currencies offline, with support for multiple categories and currencies. Their dated history shows entries in January 2019, May 2021, May 2026, and two in July 2026, indicating sparse activity spread over years with a recent cluster of entries in mid-2026. Traction leaders, all showing zero stars, are 'Unit Converter & Currency tool', 'nonius', and 'Recipe Unit Converter' in that order.

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.
