The long view
Is 91% stable, or falling fast?
A single health figure has no direction. Pro keeps the long-term record needed to show whether wear is gradual, accelerating, or approaching the point where a replacement deserves planning, and it doesn't start from nothing: the pack's own lifetime extremes and the gauge's last recalibration go back to before you installed the app.
Lifetime Analyzer for power, temperature, voltage, and charge
Monthly health and cycle history per device
Battery runway forecast for Macs
Smart alerts for unusual wear and charging conditions
Diagnosis with receipts
What drained it, and how did the charger perform?
Apps are ranked in real watts rather than a unitless energy score. Charging sessions preserve the delivered power, heat, and charger capability, so the diagnosis does not disappear as soon as you unplug. The Sleep tab covers the hours you weren't watching: charge lost overnight, wake reasons, and what's holding the Mac awake right now, honestly, including when a reading can't be trusted.

Before it dies
How do you know a keyboard is about to die?
A Bluetooth accessory reports a charge level and nothing else: no health, no cycles, no warning. Pro records that level over time and turns it into a forecast, so a dead mouse in the middle of something is a thing you saw coming.
Level history per accessory, kept for months
How long is left: days for a mouse, listening time for AirPods
Roughly how long a full charge lasts
AirPods tracked per bud and case
A low-battery alert that fires before it dies, and says how long is left
Any accessory's level shown in the menu bar
Reasons to go Pro
Forecast, diagnose, explain, track, prove, and know before it dies.
Pro groups the deeper features around the decisions they help you make.

Forecast the replacement
Measure wear rate, project the window in which a Mac may reach 80% health, and catch a battery that starts ageing faster than its own trend. No projection at all until the history can support one.
Rank your apps by live watts, keep the top users over time, and record how every charge performs. Supported MacBook Pro models also identify chargers that are clearly undersized.
See exactly what happened during the last sleep: charge lost, wake count, wake reasons in plain English, and what's holding the Mac awake right now. Says so honestly when a reading can't be trusted.
Watch every Bluetooth accessory's level over time, see how long is left (days for a mouse, listening time for AirPods), and get the warning before it dies, not after.
