This is a straight scam. Any page that will not let you leave usually is. They simply want your money.
I recommend ignoring this advert entirely.

If you are interested in brain training, try something like Cambridge Brain Sciences programs, they are free
and come highly recommended by Redditors from /r/Nootropics and /r/StackAdvice:

Camila, this is not a shot at you, but as one diagnosed with early onset dementia, I understand the desperation people feel as they see their cognitive capabilities reduce very well.
Such people are then also much more vulnerable to money making scams and the aggressive tactics sometimes used. PM me if you'd like to talk.
Just in case you don't know, there is a cool google group dedicated to n back: https://groups.google.com/forum/m/#!forum/brain-training
Also there is a SourceForge n back download that offers many different types of n back exercises:
It's all good brother. Thanks for trying.
Please play the full PC version (free) of the game by downloading it through http://brainworkshop.sourceforge.net/
You could increase/decrease NBack, trials, speed. You could even add sounds, images, math.
I suck at this game by the way. lol! Great game to pass time and keep the brain active.
Check out the Multiple Mentality by Harry Kahne.
You might as well try Dual n-Back for one hour of actual playing a day (though not at first, but build up to it).
For meditation and more calmness overall, check out the book The Mind Illuminated by John Yates.
Beware of other basics like sleep, No Fap, nutritional deficiencies, supplements and vitamins etc.
As the other commenter said: brain workshop. It is free, and Dual n-Back and its variants (Triple, Quadruple, Combination n-Back etc.) will keep you busy for a long time. Train it daily. It is tough initially, but you'll progress. If you really want your bang for buck aim to train one hour daily (though not in the first weeks).

As a bonus, check out the multiple mentality program by Harry Kahne. It is also tough and also demands daily training.

If you have the ambition and put in the effort, you'll reap the rewards within the first months.
Reviews on Amazon seem to indicate it's good for your bowels. . . As in diarrhea and vomiting. . .

I can't find a lot of credible scientific evidence behind most brain training apps/systems, personally most of it seems like placebo and advancement on the learning curves of specific tasks.
From the literature and from personal experience, I believe that Dual N-Back (I use it on android but there should be decent iOS versions) actually produces measurable results and noticeable impact on my memory and intelligence.
