Ever been stuck at home when your mates are out whooping it up nearby? Can't find your buddy at a heaving gig? Now you can pinpoint your nearest and dearest using your mobile.

Social Network Integrated Friend Finder – or SNIFF if you prefer – uses signals from your mobile to help you locate mates when ringing's not an option.

Here's how it works – you sign up on the Sniff site, invite your mates to join, and then whnever you want to know where they are, simply "SNIFF" them (although I'm not sure how many of my mates I would actually want to sniff). If your mate accepts your Sniff, you'll be able to pinpoint their location on a map.

On first glance this does sound slightly stalkerish, especially when you find out that the tech involved was originally used by police to track down suspects or missing children, but your mates have to opt in to the service and can choose to be "invisible" whenever they choose.

The service currently costs 50p per Sniff, and has been massive in Scandinavia, where there are over 10,000 keen Sniffers already. Costs are planned to be lowered if ads are supported. Oh, and you can also add it as a Facebook app, naturally.

Brian Levin, CEO of parent company, Useful Networks says: "It's an easy and convenient way to answer the most asked question on a mobile." We say – why not just text "Where are you?" instead. For less than 50p.

In saying that, I can see Sniff being awesomely useful for Glastonbury – as "er, I'm in a field next to a guy playing bongos" is often not enough to locate your mates. That's if you can get a signal at Glasto, that is...
