CLUSTER ARITHMETIC-CALCULATOR-OPERATIONS · 26 ENTRIES · EARLIEST ENTRY 2026-07-19
Web-based calculator tools
This cluster consists of web-based calculator tools, ranging from basic arithmetic to specialized functions like pottery calculations, z-scores, fertilizer amounts, and combinations. The dated history before the index start is too thin to discern a trend, with only four dated entries and fifteen undated. Traction leaders are Calculator- (1 star), calculator and kalkulator.vue (0 stars each).
Entry timeline
ENTRY TIMELINE
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.
