Have had an account for 2 years now, have never had issues! It's great!
They release new games, new challenges and recently launched the mobile app. My Android phone runs it perfectly. (It's the first version of the app, there will be more games added soon it says)
I've track my progress, while the numbers say I'm getting quicker with better memory, I've actually noticed a change myself. People's names, driving directions, quick math, I've impressed myself sometimes.
You have to stay at it! I do it 3-4 times a week. Lunchbreaks usually.
If you stop using it, you'll performance will decrease.
Maybe this is where all the bad reviews come from... dumb people!
It will not make you MAGICALLY smarter.
As far as the price, I used to buy video games, $29.99, $59.99, $79.99, play them for 3 weeks and shelf them. Hundreds of dollars a year.
Now that I'm not a kid anymore, $60 a year for Lumosity, is easily justifiable.
You pay for a gym membership for special machines and equipment, but you can't fork over $60/yr for your brain. Oh gosh. I fear where the world is headed!

Highly recommend it to anyone who wants to stay sharp and keep their brain active.

I don't know how it could be a scam, you pay, and you receive a service.
I got my family hooked and we pay for a Family Plan. No complaints.
