CLUSTER CALCULATIONS-FUNCTIONS-PERFORMS · 5 ENTRIES · EARLIEST ENTRY unknown

Web-based scientific calculators

This cluster comprises web-based scientific calculator tools covering trigonometric, logarithmic, algebraic, and engineering functions, often with angle modes, history, and memory features. The dated history is too thin to read a shape from—only one dated entry exists before the index start, and five members have no source date. Traction leaders by activity signal are SciCal600 (0 stars), fastapi-engineering-calculator (1 star), and KCalc (0 stars), though star counts are minimal.

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 5 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.
