PC power cost monitoring apps

These desktop apps measure a PC's real power draw, estimate electricity cost from a user-defined tariff, and some attribute usage to specific applications, with one also tracking half-hourly smart-tariff rates. The cluster's dated history is too thin to read a shape from – it predates the index or its members are undated. Nabatt leads on traction with 2 stars.

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.
