Download FAST for macOS
The current notarized build, straight from justfast.app. FAST needs a license key to run — the download itself is the same file for everyone.

You need a license key. FAST asks for one on first launch and does not run without it. If you have not bought FAST yet, start at pricing — one-time purchase, no subscription. If you have, the key is in your Polar receipt and customer portal.
Signed with a Developer ID and notarized by Apple, so it opens normally — you should never have to bypass a security warning or weaken System Integrity Protection. The installation steps cover moving it to Applications, granting Accessibility permission and activating your key.
Later versions
You only need this page once. FAST checks for updates itself and installs them over a signed feed; every update is included in the one-time purchase. Past releases are listed in the changelog.
Verify the download
Optional, and worth it if you got the link from anywhere other than this page. In Terminal:
shasum -a 256 ~/Downloads/FAST-1.0.0.dmgThe result must be exactly:
c9625b72b5223fccf41244ab25a9b1e4c874dd825affe731c7f07c8b1c7cbb58
