Why did Google Brands Accelerator recognize memoryOS as being 'Light Years Ahead' in the memory space?

• memoryOS delivers results:

During our pre-launch phase, thousands of users completed our demo and, on average, had a 70% increase in recall and a 60% increase in recall speed just after the first ~40min session.

• Providing your mind with structured storage space:

We have spent tens of thousands of hours creating and optimizing our Virtual Mind Palaces, so you don’t have to spend months constructing your own the hard way. These virtual palaces serve as blueprints for your mind's storage space, allowing you to easily encode, store and recall like a memory champion.

• A proven innovative approach that works:

During our research and development stage, thousands of people of all age groups and even those with difficult medical conditions found memoryOS as an effective and useful tool. Actual results exceeded our team’s expectations.

• Gamified edtech at its best:

memoryOS has proven to work on people with no prior gaming experience - anyone can use it. Utilizing the power of the Unity game engine, memoryOS is widely accessible on all mobile and tablet devices and is soon coming to VR.

## MemoryOS Reviews in Argentina

### *---- "Unclear billing and unauthorized charge after plan ended"
I had a six-month plan that ended recently. After it expired, the app tried to automatically renew it, but my card didn’t have enough funds. I wanted to cancel the renewal or remove my payment method, but there was no option in the app to do so.

I contacted support, and they assured me there was no active subscription and no charges would occur. However, the next day I was still charged $75 — after a previous failed attempt to charge more than $90. This makes the situation feel very suspicious and untrustworthy.

Please fix your billing system and make cancellation options clearly available. I’ve requested a refund and cancellation of any subscription. Users should be careful until this issue is resolved.
-- pablo_azkaban, 2025-10-15

### *---- "A charge of USD 99,99  is not a free version"
I download the app and after a couple of days I canceled the subscription. I see a charge of 99,99 dollars with my no acceptance in my credit card. That’s unacceptable!
-- Acardona974, 2025-03-25

### **--- "No free version + too expensive"
No free version is criminal, also 150 a year in one payment doest help
-- ffffertyhc468, 2025-01-07

### ***** "Very effective step by step approach to memory training"
I’m a 50 year old accountant and needed to improve my focus with budgets and balancing accounts for closings of fiscal years. I bought books about memory training. Books are helpful but this step by step guided approach is much more effective.  I could not concentrate enough to finish the books. This app is like having a memory coach for you. At first I thought the lesson about memorizing 50 digits of Pi was impossible for me. Now I memorized 150 digits of Pi and intend to keep on adding more digits. And much more than that, I can read the memory books entirely.  I concentrate much more on the memory exercises. My focus on my accounting job is way better. This app is not cheap but I definitely recommend it . It is worth the price.
