CLUSTER BAR-BATTERY-MENU · 39 ENTRIES · EARLIEST ENTRY 2026-08-16

macOS power monitoring utilities

This cluster comprises macOS menu bar apps and preference panes that monitor and control power flow, battery state, charging behavior, and connected energy or smart devices such as solar inverters, chargers, and smart lights. The cluster's dated history is too thin to read a shape from — it predates the index or its members are undated. Traction leaders are Charker (7 stars), MiBar (6 stars), and BatteryWatt (1 star).

ENTRY TIMELINE

AUG 2026OCT 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 19 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.
