CLUSTER CALCULATOR-DESKTOP-SCIENTIFIC · 8 ENTRIES · EARLIEST ENTRY 2026-04-18
Desktop scientific unit calculators
The cluster consists of desktop calculator apps aimed at scientific and engineering work, with a strong emphasis on unit-aware expressions, conversions, and scriptability (variables, user-defined functions). The dated history is too thin to read a shape from: only 4 dated entries exist before the index start, so the cluster either predates the index or most members are undated. Traction is led by lite_calculator with 1 star, while the other two members have 0 stars.
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 8 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.
