This is probably the best app you can have on our iPhone, it works even better than the original tom tom GPS navigator sold at the store, it is actually worth the price but you can have it for free following the guide JAILBREAK on my website, there are tom tom app for almost every nation world wide, like USA, CANADA, MEXICO , ITALY ,EUROPE, AUSTRALIA, BRAZIL ETC... The following link is for Tom Tom Europe which is an excellent GPS for your car. If you want it for free you can.
UBER is fantastic, demanding a taxi worldwide IT BECOME SO EASY, give it a try and put the code MKAUL into the promotion box to receive 20 $ credit.
This app is practical, you can create an account and store all your cards codes and bar codes from grocery store cards to credit cards etc.. .
I think is the best QR reader, you can have it for free with a jailbroken iPhone.
Using your location it gives good advice on where to go , what to eat etc...
