A cyclist and app developer has come up with an iPhone app that sends out an alert if a disaster such as a crash happens while you're out for a ride.

Ross McCracken says the idea for Find Me Fast "came from riding in deserted and quiet areas alone whilst thinking: 'If I crashed over that barrier or into that ditch would anyone find me?'"

The way it works is simple. You activate the app at the beginning of your ride and if it doesn't detect motion for a set time it sounds an audible alarm on your phone. If you don't respond to that alarm, the app sends a text to your chosen emergency contact with your location  and a link to Google Maps.

There is also a manual SOS option. With two clicks the user can send the nature of their emergency and their location to call for assistance. "Easier, quicker and more accurate than trying to explain over the phone where you are!" says McCracken.

You can use location-sharing apps such as Glympse, or the ride-following function of the most recent Garmin GPS units so that someone at home can keep an eye on where you are, but we like the idea of an app that sends an alert if you're stationary for too long. Just don't leave your phone in your saddle bag at a pub stop.

Find Me Fast costs £2.99 from the Apple iTunes Store.
