App of the week; Gadgets.
Though the virtual control wheel takes some getting used to (lifting your thumb off the wheel at any point during a race can make you veer wildly off course), once you've got the hang of it, it becomes incredibly responsive.
Perform well and you earn coins with which to "pimp your rides", giving you speed and acceleration boosts that will become invaluable over the course of the campaign's 36 tracks. Thankfully, in-app purchases are kept to a minimum - there's nothing that can be bought that quick reflexes can't also deliver.
Game Center multiplayer options are also included. Ghost Car races can be played asynchronously with a remote friend, while 5 local Wi-Fi players and 3 local Bluetooth players can duke it out in real time.
It's not the most visually advanced game of all time, but pin-sharp retina graphics and detailed tracks that play with perspective are attractive, with nice graphical flourishes such as off-road dust clouds and wheel spin smoke.
