A free online timer, stopwatch and countdown clock that runs entirely in your browser. No account, nothing to install.
It keeps working offline once loaded, and you can add it to your home screen like an app. Your settings stay in your own browser.
Press Voice control and allow microphone access, then speak normally. Your speech is handled by your browser's own speech service, and nothing is stored by this page. Allow the microphone once and switch this on once, and it stays on as you move around the whole site, in this tab or a new one. It switches itself off after an hour of not being used. The button always shows whether it is listening, and tapping it stops it for good.
