CLUSTER ARITHMETIC-BASIC-CALCULATOR-2 · 18 ENTRIES · EARLIEST ENTRY unknown

OS-style calculator web apps

This cluster consists of web-based calculator apps that replicate the visual style of operating-system calculators—notably iOS, with macOS and Windows 7 variants—and perform only basic arithmetic. The dated history is too thin to read a shape from, as no members have usable source dates prior to the index start; the cluster predates the index or its members are undated. All members show effectively no traction, with the top activity signals (Windows 7 Calculator, DragonOsman JavaScript Calculator Project, iOS Style Calculator) each sitting at zero stars.

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 18 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
