Hold your charge

Keep the battery between 75–80% to slow aging, pause charging when it runs hot, and override with one click when you need a full tank.

Real watts, live

Actual wall power in, system draw, and battery flow — with animated direction, so you always know which way the energy is moving.

Is it delivering?

Chargers benchmarked against their rating, Ethernet that fell from 2.5G to 1G, displays stuck below their max refresh, USB on a slow link — flagged.

Dock health at a glance

Sit down, plug in, one look: power ✓ network ✓ display ✓ USB ✓ — or exactly which cable is letting you down.

Plain English

"macOS is deliberately holding your charge to slow battery aging" beats a mystery. Every state explains itself and offers the next step.

Widgets & devices

Desktop widgets in three sizes, AirPods and Magic accessory batteries, per-app energy, and a dashboard with history for everything.

Requires an Apple Silicon Mac (M1 or later) on macOS 14+ — Intel Macs are not supported. Optional superpowers (charge limits, power modes, per-app energy) use a small helper you approve once in System Settings — removable anytime.
