Open the menu bar panel for right now, the Details window for longer stretches, and keep the widget on your desktop for the last hour.

Readings
Not every watt means the same thing.
Voltyn shows three readings separately and labels each one.
- System powerWhat your Mac uses
- Overall power your Mac is using now. Live in the menu bar; a one-hour mean in the widget.
- Input powerWhat comes in
- Power read on the supply input side. With no usable value, Voltyn never substitutes adapter capability or zero.
- Adapter capabilityWhat the charger can offer
- The most your charger reports it can deliver, such as 100 W. Not what your Mac is using or charging at.
Your power history stays on your Mac. No account, no ads, no automatic telemetry, and no analytics on this website.

Before you buy.
Full support guideWhich Macs does Voltyn support?
MacBook models with Apple silicon (M-series chips) running macOS 14 or later. Intel Macs and desktop Macs are not supported.
Is it a subscription?
No. Voltyn is a one-time purchase on the Mac App Store with no subscription and no in-app purchases. The price shown on the App Store for your region applies.
My charger says 100 W. Why is the reading lower?
Adapter capability is the most your charger can deliver, system power is what your Mac is using, and input power is the current reading on the supply side. A lower reading does not mean your charger or cable is faulty.
Why do the widget and menu bar show different numbers?
The menu bar shows live system power, while the medium widget shows a recorded one-hour mean tied to its snapshot time. Different time scales usually mean different numbers.
Does Voltyn upload my data?
Not automatically. Recorded power history stays on your Mac with no automatic telemetry. Content only leaves your device when you send an email, screenshot or feedback yourself.
