About Utility Tools

Small everyday tools that just work

Some jobs need a tool for a minute, not an app for good. These free utilities run in your browser with nothing to install: open the page, use it and close it.

Timer and microphone

Timing: the countdown timer counts down hours, minutes and seconds and sounds an alarm at the end, and it keeps running in the background.
Audio check: the microphone test shows your input level live, displays a frequency view and records a 10-second clip so you hear how you sound before a call.

For timing between dates rather than minutes, see the date calculator, and for recordings and clips the audio and video tools.

Tips

If the microphone level does not move, check the mute switch and the input device in your system sound settings.
Close other apps that use the microphone, such as a video call, before you test it.
Keep the timer tab open; closing the tab stops the countdown.
