Version 2.7 of App Tamer is out of beta testing and available for download. Details and download links are on the App Tamer release page.
In case you missed the beta versions and accompanying blog posts, the marquee feature of this release is the ability to run an app on the M1’s efficiency cores instead of on the more power-hungry performance cores when you’re not actively using it.

App Tamer 2.7 also augments its interface with additional performance information to let you manage CPU and power consumption intelligently. In addition to showing overall CPU usage, it breaks it down by processor core type, giving separate stats for the M1 performance and efficiency cores. They’re included textually and graphically in App Tamer’s window, and also (optionally) as tiny ‘P’ and ‘E’ values in its menu bar display:
Conserving battery and limiting CPU usage is really as simple as clicking that checkbox, but there’s a lot going on under the hood. This blog post discusses how things operate in more detail.
