If you're in an area that's sadly bereft of a decent 3G connection, you may well find yourself spending a lot of time on the iPhone's WiFi connection screen. However, it's largely been designed to find you strong connections that'll be strong enough to actually use. Makes sense, doesn't it?

WifiTrak takes WiFi scanning to the next level, showing you just about every connection there's even a sniff of. In our testing, we found that generally unearthed a good few more than the built-in scanner.

For quick scanning of the results list, WifiTrak gives each network a coloured icon that'll instantly show you how strong the signal is and whether it's using some form of encryption. However, underneath the network's actual name, it does into a little more detail.

Here, you can see a numerical value for the signal strength and exactly what sort of encryption it's using, if any. We're not sure what use it is knowing whether a connection's encrypted using WPA or WEP is you haven't got the code though - unless you're blessed with Neo-esque hacking powers.

You'll generally find that the additional networks WifiTrak finds aren't actually of much use - they'll probably be pretty low on the strength-o-meter, and since the app can't tell you exactly where the connections are coming from, there's no way to use it as a magic Wi-Fi divining rod either.

However, all is not lost. Within the setting menu, there's a feature that's genuinely useful if you're out and about in search of a usable WiFi connection. You can make WifiTrak play an alert whenever it finds an open network that's above a certain strength, which you can handily set yourself. You can also change how often WifiTrak rescans for connectivity - although your battery will obviously take the hit if you let the app get a little over zealous.

So, for all WifiTrak's connection scanning powers, for most of us it'll be of most use as a simple 'ding ding' alert bot for when you stumble upon a WiFi hotspot.

WifiTrak doesn't perform miracles, and if you only occasionally find yourself in dire need of WiFi, you'll probably be just as well equipped with the built-in scanner. However, if you often find yourself wandering around town, eyes glued to the iPhone's screen in the hope that an open network will pop up, WifiTrak will at least let you watch where you're going.
