Website easy to navigate, I used an iPad mini to sign up for an account. After signing up by supplying my birthdate and an email address rather than using my FB login (doing so gives them access to your friends list and google activity). I then answered a few more questions. After being redirected to the home page, I tried to access the "limited" games that are free. All of the games, tests, and other account items are all locked. It appears that if you are an iPad user the only thing free is the ability to sign up for a lumosity account, you must pay to access and use everything as an iPad or iPad mini user.
