Construction cost estimating apps

This cluster consists of web apps for estimating construction project costs, covering materials, labor, equipment, and sometimes risk contingencies, and generating shareable summaries or maintained estimate documents. The cluster's dated history is too thin to read a shape from: only four dated entries exist before the index start, so it predates the index or its members are undated. On traction, uchet-objektov leads with 2 stars, followed by smekta and concrete-strength-calculator with 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 20 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
