Sometimes you just need a reliable time keeper while you work on a tune. You don't always remember to bring your metronome with you as you go through your day. Now, you can have one with you, ready to work when you are. MetronomeOnline.com is an online web app that has tempo settings from timing, style and mode. You can change all the important parameters.
They also have purchasable cell phone versions available, but they charge for those. It's not necessary to pay, since either Android or iPhone both contain free metronome apps in their respective markets.
If you need an online metronome, though, this free, usable and well thought interface is a nice quick web answer.
