CLUSTER CATEGORIES-CONVERTER-UNIT · 30 ENTRIES · EARLIEST ENTRY 2017-01-16

Unit converter mobile apps

The cluster consists of mobile unit converter apps, primarily for iOS, that cover a wide range of measurement categories (e.g., 14 to 80 categories) and offer features like offline access, favorites, history, and currency conversion. The dated history before the index start is long but thin, with entries scattered from December 2010 through June 2026 and occasional small groupings (e.g., two entries in 2023 and three in 2026), showing no clear trend. None of the three traction leaders (Metrica: Units Converter, ConvertALL Unit Converter, Unit converter - UnitFlow) have star counts above zero, so engagement is minimal across the cluster.

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.
