I used Lumosity for a year and had no trouble canceling when subscription period came to an end. I'm surprised to see all the negative reviews about auto-renewal. It seems like these people didn't read the terms when they signed up. I really enjoyed the games and found them challenging and Lumosity added new ones frequently. I'm planning to start my subscription again, but while I was doing price research, I stumbled upon these reviews and just thought I'd chime in with a different perspective.
