The site seemed like a good way to help improve my memory and attentiveness, but after 6 weeks my scores on "the brain test" dropped by over 10 points. Why? Because the applications are so erratic that it was impossible to navigate through them so the clock ticked away while waiting for something (anything) to happen. When I requested a refund due to this poor performance, I was told it's beyond 30 days and we don't give you anything after that. Poor applications, poor service. Stay far away.
