CLUSTER ARITHMETIC-BASIC-CALCULATIONS-2 · 4 ENTRIES · EARLIEST ENTRY unknown

Basic arithmetic calculator web apps

This cluster consists of simple web apps that perform basic arithmetic for quick, everyday number crunching. The dated history is too thin to read a shape from — the cluster has zero dated entries before the index start, so it predates the index or its members are undated. Traction leaders are all tied at 0 stars: Simple Calculator App and two entries named Simple Calculator.

Entry timeline

ENTRY TIMELINE

AUG 2026: 4
AUG 2026

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 4 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.
