Best iPhone apps this week

GetTaxi £free

This indispensable app is ideal for flagging down a black cab with minimal fuss. A recent update adds a Taxi Radar which shows you the nearest cabs available and how long they'll take to arrive, and you get pics of your driver, his license plate, telephone number and past rating sent to you while you wait, for peace of mind. GetTaxi's even booked up thousands of hours' worth of taxis for the Olympics, to ensure easier travel during the inevitable chaos.
