Why are my ipad apps using so much memory?
When i download an app on my ipad 3 its usually like 10-20 mb at most and then when i go into the settings app and go to see the usage it goes up dramatically for example i downloaded an app called touchretouch its really useful for photo editing its like 16.5 mb and when i checked the usage like a week later it went up to 115 mb it says (data and documents)...why?.....i have a bunch of apps like that, like facebook uses almost 200 mb....its ridiculous...is there a way to reduce the amount of memory.....and i rarely use most of the apps so i dont know why its using so much data, and for the documents part i have no idea why.....
