Efficiently manage your CPU cycles, save energy, and more. App Tamer tames your processor-monopolizing apps and keeps them from chewing up excessive CPU time and battery life. Powered by a unique AutoStop feature, App Tamer stops each application when you switch away from it — when you return to that app, it restarts automatically!

App Tamer Does All The Work
- Unlike some utilities that let you manually stop 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 so they don’t use more than a certain amount of CPU.
- 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 Starcraft.
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.
- By default, App Tamer will now slow down Microsoft Edge when Edge is running in the background.
- Added support for Coherence and other apps that create site-specific browsers based on Google Chrome.
- A warning is shown when you slow down Spotlight, as this may adversely affect applications that depend upon Spotlight.
- App Tamer’s performance has been greatly improved when apps like Epichrome or shell scripts make frequent, repeated calls to the sleep, kill, and lsof shell commands.
- If App Tamer is configured to run in the background (not showing its icon in the Dock), it will ignore Command-Q when its window is open so you don’t accidentally quit it.
- Google Chrome apps are now handled correctly. If a Chrome app is configured not to slow down, Chrome will be kept running at full speed so that it can serve as the “engine” for the app without compromising the app’s performance.
