Gongfu Timer for macOS should begin downloading now.
Didn't start? Download it here.
The Mac build isn't notarized by Apple yet, so the first time you open it macOS asks you to confirm — you may see “Gongfu Timer can't be opened because Apple cannot check it for malicious software.” It's expected and safe. Just open it once this way:
xattr -dr com.apple.quarantine "/Applications/Gongfu Timer.app"
A properly signed & notarized build (no warnings at all) is on the roadmap. Still stuck? See support.
