Looking for an Endurance alternative?

Updated 18 August 2026 · competitor facts checked on that date · disclosure: WattMate is our app, and for some jobs the honest pick isn't us — Endurance runs on Intel Macs and back to macOS 10.13; we run on neither

Credit where it's due: Endurance has been doing this since 2015, and it does something we deliberately don't. It acts. When the charge drops past a level you set, it dims the screen gradually, hides background apps so macOS App Nap puts them to sleep, suspends background browsers, and pauses background services. One payment of $20, or it comes with Setapp, and there's a two-week demo. If you want the machine to just stretch what's left without you thinking about it, that is exactly what it's for.

WattMate is the opposite philosophy, and it's worth being blunt about it: it acts on nothing. It doesn't dim, throttle, hide or pause a single thing. It measures, names what's spending the charge, and tells you what quitting it would buy — then checks whether it was right.

Acting and accounting

The difference shows up in what each one can tell you afterwards. Endurance's promise is "about 20% more runtime" — their own words, from their own testing. That's a claim about their machine under their load. It isn't a claim about your Mac this afternoon, and the app doesn't come back later to check it on yours.

WattMate names a number before you do anything — quit this, get about 12 minutes back — and two minutes after you quit, it re-measures and prints what actually changed. When the effect can't be separated from everything else happening at the time, it says that instead of taking the credit. That's the whole reason the app exists: a projection you can't check is a vibe.

There's also a units difference worth knowing if you're comparing readouts. Endurance reports app energy the way macOS does, as Apple's dimensionless "Energy Impact" score. WattMate reports watts, read from the chip's own energy counters, because a score can't be turned into minutes and a watt can.

Side by side

One thing worth checking before you buy: the newest entry in Endurance's own update feed (enduranceapp.com/appcast.xml) is version 3.2.6, dated 28 November 2022, while the download button on their site serves 3.3.0 — so the app's built-in update check has nothing newer to find than a build from 2022. Checked 18 August 2026. We haven't run the app ourselves, and this is a fact about their update feed, not a verdict about their software.

Who should pick which

Pick Endurance if you want the Mac to stretch the charge by itself and you'd rather not think about which app is at fault — or if you're on an Intel Mac or an older macOS, where WattMate simply doesn't run. Those aren't consolation reasons; for a lot of people they're the whole decision.

Pick WattMate if dimming and pausing feels like treating the symptom and you want the cause named. One app is usually most of the bill, and knowing which one — with the minutes it costs you, checked afterwards — is a different kind of fix than making everything a bit slower.
