i3 Mindware Reviews & Testimonials

This is from a review by Andrew Clark, previously COO of Bulletproof Executive.

Dave and I both use software called IQ Mindware i3…This is one of the brain hacking techniques from The Bulletproof Executive program, and it’s close to my heart because I’ve used it with great success, boosting my IQ at least 18 points (I took standardized IQ tests before and after). Dave “only” gained 12 IQ points from it, but he didn’t do as many sessions as I did, and he’d already raised his IQ with other methods.

From an efficiency perspective, that’s incredible. I gained 2.75 IQ points for every hour of brain training I did

Here’s a graph of my N level for my first 20 sessions (total of just 6.5 hours of training):


i3 Mindware review

The best part about [the] training is that it’s permanent. After the 20 sessions you see above I did no training for a full 8 months to see if I’d forget the skill and have to start over. The results were an astounding OPPOSITE of what I expected, as if my brain had further optimized itself during the 8 months off.

I’ve used a Zeo to track my sleep patterns after N-back training to see what my brain was up to the following night. The result? Drastically higher REM sleep percentages, often between 30-40% of sleep–proof enough that the N-back training boosts brain optimization significantly. One night my REM even exceeded light:



Customers’ Testimonials

For 2G brain-training:

 Continue creating great products.  In less than 20 days of using i3 I could tell a marked improvement in my ability to block distractions and focus which in turn allowed me to keep more items in my workspace.

Once again you have produced another superlative series of upgrades! Thank you very much!

I have seen many similar sites / companies, so to be honest I did not expect much in the beginning, but I am impressed – I like your approach and I think you are actually putting emphasis on exactly the interventions that work.”

Yoni Donner, Stanford University

When I did the tests before starting with your software last year in the pre tests it said 125-128 and after the software in the 138-140 range and I really enjoyed using it. I have a chance at the Mensa test. 

C. Keddie

I consider this application a great resource for cognitive enhancement and continuously speak its praises to friends and co-workers. I’m an air traffic controller for the FAA and since I’ve started using your software I have noticed considerable improvements in my mental acuity while working.


My IQ was 115 on the Cattell Culture Fair III before training with i3. After 20 days of training my IQ was measured at 134 on the WAIS-IV. My IQ jumped 19 points. I do believe I’m focusing and problem solving better. Thank you for a quality product.

W Henderson,  London

I’ve always wanted to join Mensa. I came across your article on Mensa membership and this inspired me to train with i3 Mindware – in preparation for the Mensa qualifying exam. I stuck to the program, and it certainly helped me attain my life-long goal. Thank you for this software.

Jana Oster

I used i3 to prepare for a career test. I’m very happy to have used this software training program, as I felt I better understood the test questions and performed better on the test. 

A Morrison

Great Software! The training has resulted in strong improvements in my reasoning, processing speed, short term memory and visual intelligence. My IQ increased 14 points over 4 weeks.

Monica S. Hanson, CA

This is the best brain fitness software that I know of. I feel sharper and more focused, and have much more of a mental ‘buzz’ going. I am thrilled at my overall IQ improvement measured by WAIS-IV which I can only attribute to the i3 training.


In Prep-help for MCATs, this program is great. Since intelligence and problem-solving demands different factors, why not train them all? I benefitted most from improving my working memory and fluid intelligence. I am sharper, without any doubt, because of this brain training and will continue pushing my limits.

Isabel Robb,  Queensland

I scored 105 on the Matrices IQ test before training and 123 on a full scale IQ test after training. I’d say that was due mostly to the training. A little bit of familiarity helped, but the i3 training made most of the difference. I’d highly recommend this software.

O Clarke, UK

Excellent brain training software. Tougher than I expected, but motivating too. My working memory capacity increased from 2.5 to 5.5, and my IQ improved 17 points.

Lina Toscani, Roccacerro AQ

I’m very goal focused and wanted objective gains in my IQ. I was guaranteed 10-20 IQ points with this software and followed the program exactly as recommended. I took the dk.test before training and scored 112. I took the Cerebrals test after training and scored 128 – a 16 point gain. I am very happy with this result, and after four weeks, feel that the effect has been lasting.

Scientists’ Endorsements of 1G Dual N-Back Training

2G Brain Training builds on traditional (1G) dual n-back training .

Increasing intelligence is possible after all …with more training leading to greater gains …across the spectrum of abilities. …Almost 40 years ago, Jensen claimed that, when all is said and done, there is not much one can do to raise people’s IQs. Jaeggi and her colleagues have made an important contribution… by showing that intelligence is trainable to a significant and meaningful degree.

Robert Sternberg, Professor of Cognitive Psychology, Indiana University

I know, there is a huge market of software concerning brain training, IQ-training, and so on. But there is no real scientific evidence that these programs actually work, that is, that they actually boost intelligence or train something else than the task itself, at least in young adults. The … fact that we reliably showed transfer effects after training, and moreover, that we showed transfer to such an important function as fluid intelligence is avery new and exciting finding in our field.

Dr Susanne Jaeggi, University of Michigan

It it is possible that these exercises aid with nerve cell growth or nerve cell function in some way or alter neurological function in some way… The results are exciting and have implications for a wide variety of fields including alzheimer’s and other dementias.

The Scientific Press on 1G Dual N-Back Training

Simple Brain Exercise Can Boost IQ

Can mental training improve your intelligence? No video game or mental puzzle has convincingly been shown to work. But now a group of neuropsychologists claims it has found a task that can add points to a person’s IQ – and the harder you train, they say, the more you gain.

Smarten Up. Practicing a Challenging Memory Task Spurs a Surprising Intelligence Gain

If you’re looking for an intellectual picker-upper that doesn’t come in a pill, remember this: A relatively brief memory-training program jump-starts general reasoning skills and problem-solving proficiency, according to a new study.

Training Can Increase Fluid Intelligence, Once Thought To Be Fixed At Birth

Can human beings rev up their intelligence quotients, or are they stuck with IQs set by their genes at birth? Until recently, nature seemed to be the clear winner over nurture. …But new research, led by Swiss postdoctoral fellows Susanne M. Jaeggi and Martin Buschkuehl, working at the University of Michigan in Ann Arbor, suggests that at least one aspect of a person’s IQ can be improved by training a certain type of memory.

Crystallized intelligence draws on existing skills, knowledge and experiences to solve problems … Fluid intelligence draws on the ability to understand relationships between various concepts, independent of any previous knowledge or skills, to solve new problems. The research shows that this part of intelligence can be improved through memory training. …General intelligence is a key to determining life outcomes such as academic success, job performance and occupational advancement … Researchers also surmise that this same type of memory training may help children with developmental problems and older adults who face memory decline.
