Switch, restore & hide apps in a click
Click any app in the list to bring it forward — even a window you’d minimized to the Dock comes right back. Click it again to hide it: a quick way to jump between what’s running, right from the menu bar.
A tiny menu-bar utility that suspends the background apps quietly draining your battery. How much you save depends on what you leave running — and on a heavy app you'd forgotten about, freezing cut ~85% of its drain in our tests. Start free on the Mac App Store, or unlock automatic freezing with Pro.

Everything the Lite monitor shows you — plus the power to act on it.
Background apps quietly drain power. Hit Freeze All and watch the draw fall.
Freeze just the apps you don't need right now — each one trims the draw a little further.
For illustration only. These two clips are a demonstration of the idea, not a recording of
real measurements. The energy graph is a simulation — AppFreeze suspends apps to cut their CPU use; it does
not measure wattage, and actual battery savings vary by app and workload.
Activity Monitor is Apple’s own utility, shown here purely to illustrate the concept — it is not part
of AppFreeze.
Want the real numbers? We measured the actual effect on real
hardware — CPU power, battery drain, calibration. See the full methodology,

Click any app in the list to bring it forward — even a window you’d minimized to the Dock comes right back. Click it again to hide it: a quick way to jump between what’s running, right from the menu bar.
Freeze every background app at once, or auto-freeze a remembered set. Suspended apps stop using the CPU instantly — no quitting, no losing your work.
Apps thaw the moment you switch to them and refreeze when you leave. You get the battery savings without ever thinking about it.
See real per-app CPU usage with a colour-coded Low/Medium/High indicator, so you know exactly which apps are draining your battery.
Click any column header — Name, %CPU or memory — to re-sort the list, ascending or descending. Surface your biggest battery hogs in one click.
Set how many apps the list shows — tap to grow it taller when you’re juggling everything, or keep it compact for just the essentials. The panel resizes to match, so it never takes more space than you need.
Hover any app for a close button and shut it down right from the menu bar — with a quick confirm so you never lose unsaved work by accident.
Record your own global freeze shortcut (or reset it to the default) and have AppFreeze ready in your menu bar the moment you log in — every setting tucked into one tidy panel.
Right-click any app to lock it — it stays unfrozen no matter what mode you switch to. A lock icon marks it at a glance; click the lock to unlock.
AppFreeze never suspends the app you’re using, Finder, or critical system processes — your Mac stays responsive at all times.
No memory cleaners, no magic — just how Unix already works.
AppFreeze sends a SIGSTOP signal — the same primitive macOS
uses internally. The app freezes in place and its CPU drops to zero.
SIGCONT wakes it instantly, exactly where it left off.
Nothing is killed, nothing is lost.
Sending signals to other processes is a privileged operation Apple’s sandbox doesn’t allow. So Lite is a read-only monitor on the App Store, and the actual freezing lives in Pro — distributed directly and on Setapp.
The app you’re using, Finder, the Dock and core system processes are never frozen — by design. Your Mac stays responsive at all times.
AppFreeze manages the applications you opened — the ones you can see and chose to run. It deliberately leaves invisible background and system processes alone: you never launched them, so it’s not its place to touch them.
