Brainwiki Arvostelua 

They state “faster reactions,” but software lag and UI delays ruin the experience entirely.

I visited the site because I've never done an IQ test, and they advertised theirs at $1. The test was incredibly short (done in 5-10 mins) and even for my first time seemed incredibly shallow for a paid test, even for $1. This is where my real problems began. I was repeatedly charged $25 after my initial confirmed charge of $1 for the test. I had not revisited the site. I had not been charged previously for this or made any action to provide for this/these charges. Thanks to chase fraud alert I was able to cancel 2 of 3 charges, one still being pending. All were traceable directly back to brainwiki.com; emailing them will not help you, calling their incompetent service line will not help you. If you have this problem, you must log back in to cancel the subscription that was likely NOT disclosed to you, even during the payment process. Otherwise, DO NOT VISIT THIS SITE 😭 (This review was written in the midst of an intense rage towards the unrivalled most dull-witted nincompoop of a service person in existence on their line)

The “achievement certificates” are worthless. Digital trophies that mean little when skills do not improve.

Free version sells illusion of value, then pushes paywall aggressively. Feels manipulative.

I feel brainwiki takes advantage of people wanting self-improvement, charging for comfort rather than results.

Trainer says “adapts,” but adapts poorly. Either too easy or too frustrating, never just right.

Emails about “your progress” are clearly marketing; they try to keep you subscribed.

Free period is short; after that full price kicks in without fair notice. Unethical in my view.
