Questions

Good to know

Does Tend send my data anywhere?

No. Every measurement happens on your Mac and stays there. Tend only contacts its server to check for updates and, after launch, to verify a Pro license.

Which Macs does it support?

Macs with Apple silicon running macOS 15 or later. Battery features need a MacBook; everything else works on desktops too.

Will Tend slow my Mac down?

It's built to stay out of the way: about 2% CPU while its window is open and around 0.3% in the background, with motion turned off automatically in Low Power Mode.

What happens when the beta ends?

The free features stay free. Pro features move to a paid plan, and founding members keep their discount for life.
