I don't know if this has been posted, I searched and found nothing about this website. Basically everyday they give you a free App, for iPhone, iPad, and ANDROID!
Right now they only have two Apps, but they said it will be in normal running mode such as the iPhone one, in September. So bookmark the page and check on it until it updates!
*These are legit free Applications, that the people at freeappaday.com ask the developer to make free for just one day*
