Mac 4 Breakfast review

Updated 23 August 2026 · everything here comes from their own pages, checked on that date. We have not measured their app. Disclosure: WattMate is our app, and this is the closest product on the market to what we do. Who measures this.

Battery health, cycles, live watts, a sleep-drain breakdown and every open app with the watt-hours it has used since launch, in one menu bar app with a free tier. Of everything we looked at, this is the product closest to ours in intent.

What it says it does

Their home page sums it up as "Health, charge, sleep-drain and every Apple device. Everything macOS hides, in one native app."

The per-app part is described precisely enough to compare: "Every open app with how long it has been open and the energy it has actually consumed since launch: real watt-hours from macOS's own per-app counters." Separately, the Pro list promises "See which apps are using significant energy, live".

Price, and a date that matters

The $4.99 has an expiry printed on their own page: "Launch price ends 31 August · $4.99 one-time, then back to $9.99". If you are reading this in September or later, assume $9.99 and check their page.

Where it is better than ours

There is a free tier, and it is not a stub. Health, capacity, condition, cycles, temperature and the menu bar percentage are all in it. Ours has a ten-day trial and then a price.

The breadth per pound is unmatched in this category. At their launch price, a one-time payment covers per-app energy, remaining-time estimates, notifications, iPhone, iPad, AirPods and Watch levels, and a sleep breakdown. Nothing else we surveyed covers that range at that price.

It reads other Apple devices. We do not.

Where we do something different

Per-app energy is not the difference: they have it, we have it, and so do two others in this category. The difference is direction. Their figure is what an app has used since it launched, accumulated backwards. Their time estimate is for the machine as a whole, phrased as "About 14 minutes left".

Ours points forwards and then checks itself: a number of minutes attached to one specific app before you quit it, then a re-measurement two minutes afterwards printing what actually changed, or stating that the effect could not be isolated. Searched across their pages on 23 August 2026, a promise of that shape is not claimed.

Which of the two you want depends on the question. "Where did today's charge go" is answered by accumulated watt-hours. "What do I get if I close this thing right now" is answered by a projection that is willing to be wrong and to say so.

Who should use which

Questions people ask

Is Mac 4 Breakfast free?

There is a free tier they describe as "Free $0 forever", covering health, capacity, condition, cycles, temperature and the menu bar percentage. Per-app energy and the sleep breakdown are in the paid tier.

Is it a subscription?

No. Their wording is "Pay once. Yours forever. No subscription."

Does it run on Intel Macs?

Their pricing page states "Requires macOS 14 Sonoma or later · Apple silicon", so Intel machines are outside it. The same limit applies to us, and for us the reason is measured: the per-process energy counter compiles on Intel and silently returns zero.

Can I run it alongside WattMate?

Yes. Both read the same system counters and neither writes anything to the battery, so they do not conflict.
