CLUSTER HARVESTING-RAINWATER-WEB · 4 ENTRIES · EARLIEST ENTRY 2026-08-13

Rainwater harvesting calculator apps

This cluster consists of web applications that estimate or design rainwater harvesting systems using location, rainfall, and building data, typically recommending tank sizes. The cluster's dated history is too thin to read a shape from—there are no dated entries before the index start, so it either predates the index or its members are undated. Among the members with a source date, Paani-Bachao leads on traction with 2 stars, while the other two have 0 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 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.
