Speed testers

Need to find out how fast your internet connection is? Browse to speedtest.net or download the service’s Speed Test app for iOS devices (free, apple.co/21MsKev). Speedtest.pro Speed Test & Wi-Fi Finder (free, apple.co/21Jvblo) and Speed Test SpeedSmart (free, apple.co/21JvsVG) for iOS are worth a look too.

For something quirkier check out Architecture of Radio for iOS, (£2.29, apple.co/21Mv3OA) which provides a real-time visual representation of all the mobile masts, Wi-Fi networks and GPS satellites around you.
