This app is the reason my Macbook crashed. After exhausting all available boot-up methods and assessment techniques, the technicians at the Genius Bar concluded that there was nothing that could be done other than to restore the laptop, which meant the loss of all data on my harddrive.
AVOID this application at all costs until they fix this problem. I like the concept of the app, but never will I use it until it doesn’t corrupt and destroy the device onto which it is installed.*
*Note: It seems to work fine on iPhone, but not Macbooks.
