Made for the menu bar

The useful details are close.
The complicated ones stay out of the way.

Start with a calm, focused menu. Reveal every available reading only when curiosity strikes.

Everyday View

Everything Important, at a Glance

Charge, status, power source, time remaining, capacity health, cycles, temperature, voltage, current, and system draw, all arranged for quick scanning.

Charging Clarity

See Where the Power Goes

Keep adapter rating, USB-C PD contract, live DC input, and measured battery flow as distinct readings because they answer different questions.

Optional Depth

Go All the Way to the Cells

Inspect cell voltage spread, learned capacity, resistance, gauge history, controller counters, and lifetime extremes whenever your hardware exposes them.

Component Power

Understand the Busy Parts of Your Mac

Optional IOReport estimates for CPU, GPU, Neural Engine, memory, and displays help explain sudden power draw without turning the menu into a dashboard.

  • CPU11.8 W
  • GPU7.4 W
  • Memory2.1 W
  • Display4.8 W

A Little Emotional Intelligence

Your charge level has a face now.

The Tako shifts color and expression as your battery runs down. When you plug in, a favorite tentacle appears beside it. Useful status, without another number competing for space.

Clear Names, Honest Boundaries

Power is a story, not one magic number.

Battakorey keeps advertised capability, negotiated contracts, measured input, battery flow, and component estimates separate. Missing or implausible private readings simply disappear instead of pretending to be exact.

  • PD Contract28.0 V @ 5.0 ANegotiated
  • Live Input42.4 WMeasured
  • Battery Flow+18.7 WMeasured

Quiet by Design

Your battery data stays on your Mac.

01

No account. No analytics.

Battakorey reads local power information and does not collect or send battery data.

02

No root access.

Extra telemetry does not require disabling System Integrity Protection or running as root.

03

Graceful when unavailable.

Private AppleSMC and IOReport readings vary by Mac. Unsupported channels stay out of sight.

Battakorey is intentionally not sandboxed so it can read additional local telemetry. It is distributed directly, not through the Mac App Store. The download is signed and notarized.
