There was some recent news as of late in regards to applications tracking your location and then selling this data to other companies. This is a big nono in my book so the apps that made it to the delete and never look backlist are the following applications.
Gas Buddy – Local Gas Prices, shows a list of the cheapest gas in the area.
The Score – A sports score app that lets you follow the scores of your favorite team’s games.
If you have these on your phone I highly suggest deleting them IMMEDIATELY.
