Got Unruly Applications?

Some applications, particularly web browsers and older apps, continue running tasks or animating ads even when they're idle. That uses valuable processing (CPU) power, which leaves you with:

  • Less CPU power for the application you're using
  • Increased heat and fan noise
  • Reduced battery run-time

 

Tame Them with App Tamer

Find the culprits and get them under control. With App Tamer, you simply do this:

  1. Launch App Tamer and click on its icon in your menubar
  2. Click on an application that's using a lot of CPU
  3. Tell App Tamer to slow or stop the app

App Tamer will automatically slow down or pause your applications whenever you're not using them, greatly reducing their CPU use.

App Tamer even comes pre-configured to automatically reduce the CPU and battery usage of Safari, Firefox, Google Chrome, Spotlight, Time Machine, Photoshop, Illustrator, Word and many other applications.

Optimize your Apple Silicon Mac

App Tamer can take special advantage of Apple Silicon powered Macs, which have two different types of processor cores. Use it to automatically run busy background apps on your processor's efficiency cores to save power, leaving the performance cores for the apps you want to run fastest.

Running apps on the efficiency cores can be more than twice as efficient!

App Tamer Does All The Work

Unlike some utilities that let you manually manage processes, App Tamer automatically handles the details for you. It slows or pauses an application when you switch away from it, then automatically restarts it when you start using it again. Just set it and forget it - App Tamer quietly saves battery and CPU power while you work (or play).

But You're in Control

You choose which apps to manage. Automatically stop them when you're not using them, or just slow them down by running them on Apple Silicon's efficiency cores or limiting the amount of CPU they use.

App Tamer's preferences let you tune its behavior to your needs, whether you're frugally conserving battery power or feeding every last CPU cycle to Final Cut Pro.

Road Warriors Take Note!

Recovering even a small percentage of your CPU time can translate into significant battery savings. Stopping an application that's consuming 5% of your CPU can translate into 20 or 30 minutes of additional battery runtime.

Detect CPU Hogs

Sometimes an application or macOS system process suddenly starts using large amounts of CPU time. There may be new work to do after you've added new pictures to Photos, for example, or it could be due to a bug somewhere in an app or in macOS itself.

App Tamer detects excessive CPU usage like this and alerts you, letting you decide whether to take control or let the process continue.

What About App Nap?

Apple knows a good thing when they see it. macOS has App Nap, a feature that 's similar to App Tamer. But to activate it you have to hide or completely cover an application's windows, making it not-so-automatic. And App Nap doesn't work at all with behind-the-scenes processes like Spotlight and Time Machine. App Tamer does!

Also accelerate your Time Machine backups!

Increase the speed of your Time Machine backups with the simple click of a checkbox in your App Tamer preferences. Click here for details and caveats

What a beautifully simple yet revolutionary App! But don't tell Apple that I can put off upgrading my Macbooks for another year ;)
- Marko Turner
It's "just working". Thank you so much. Love the product. Love the support.
- Gregory Morse
A) the user interface is completely intuitive, B) it seems to work perfectly and instantaneously, and C) I did independent confirmation with my usual tool (top from the command line) and astonishingly, Safari was sitting there firmly fixed at 0 %CPU. That is awesome!!! I am absolutely going to be telling everyone I know to go buy this immediately!
