Know if your battery is fine before you replace the wrong thing.

Real screenshotHonest verdicts — even "Watch".
The question
Most apps give you numbers. You still have to interpret them.
A raw reading like 92% health and 312 cycles can be reassuring or worrying depending on the Mac, its age, its heat history, and whether the number is falling quickly. SwoopByte does the part people currently outsource to forum threads.
Raw number
92% maximum capacity at 312 cycles.
SwoopByte read
Good. This looks like normal wear for this Mac. Keep an eye on heat, but no service action is needed.
In-product verdict
Good: your battery is aging normally.
92% of original capacity at 312 cycles. That is about what we would expect for a Mac this age. Nothing to do right now.
What is included
Everything ships free.
Battery is the trust wedge for the SwoopByte family. The health verdict, history, alerts, report, and menu bar view are not held back for an upgrade prompt.
Numbers explained
Capacity, cycle count, charging status, adapter state, and temperature with context.
History and trend
Capacity and temperature over time so you can spot abnormal decline early.
Menu bar status
A quiet glanceable indicator that stays useful without nagging you.
Fair comparison
What Apple, CoconutBattery, and AlDente already do well.
SwoopByte does not pretend the built-in tools are useless. It fills the interpretation and history gap they leave open.
macOS
Apple gives you battery health and charge-limit controls. SwoopByte adds the plain-language read and trend so the percentage is not floating without context.
CoconutBattery
Good for raw battery stats. SwoopByte is for the moment after the numbers, when you want to know whether they are normal.
AlDente
Useful for power users who want charging controls (about $24.99 one-time for the paid tier). SwoopByte focuses on whether your battery is actually aging normally, and Battery stays free.
