    Frequently asked questions

    Is it accurate if I switch tabs?

    Yes. Time is measured from the system clock, so it stays accurate even if the tab is in the background.

    Does it work on my phone?

    Yes. It works in any modern browser on Windows, macOS, Linux, iPhone, iPad and Android — there is no app to install.
