Which OS does your phone have? Is it an iPhone, Android, Windows or Blackberry? I use a Blackberry Torch and highly recommend CacheSense and given that, I would also recommend it for the Android OS as well. It's a fantastic product with amazing support directly from the developer himself.
Unfortunately, I don't have an iPhone or a Windows phone, so I can't recommend anything for those OS's.
I actually use the Android OS. Ill DL it and have a looksy around the system! Thankyou so much! I wasn't sure if there even was an app. I definately had my fingers crossed though
