CLUSTER CALCULATOR-NOTATION-POLISH · 25 ENTRIES · EARLIEST ENTRY 2012-02-11
RPN and terminal calculator apps
This cluster consists of calculator applications, many emulating classic HP RPN logic or operating in terminal/command-line environments, with additional features such as bitwise operations, arbitrary precision, and scripting. The dated entries are spread thinly from 2012 to 2026, with no month having more than two entries, indicating a sparse and irregular timeline ohne accelerating trend. On traction, evline leads with 4 stars, while other listed products like SimplyRPN and SoulCalc show minimal or no activity.
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 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.
