CLUSTER CONVERSION-CALCULATOR-DESKTOP · 11 ENTRIES · EARLIEST ENTRY 2018-05-13
Desktop scientific calculator apps
This cluster consists of desktop calculator applications spanning scientific, symbolic, financial, and programming modes, with common features like unit conversion, high precision, plotting, and matrix operations. The dated history shows lone entries in 2008 and 2018, then a concentration of new entries from mid-2025 through mid-2026, with the largest monthly counts in January and April 2026. The traction leaders by activity signal are Eigen and Qalculate! (in both GTK and Qt UI variants), though all listed members show 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 11 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.
