About this app

Learn how to memorize any information, supercharge and improve your memory and brain with the most crowdfunded app in Kickstarter’s history!

memoryOS is a completely new and fun approach to enable great memory skills and learn how to memorize anything through visual memory training games. It contains interactive bite-sized lessons by a 2X World Memory Champion and an educational 3D game of Virtual Mind or Palaces - all in one easy-to-use memoryOS app.

It utilizes scientifically proven memory techniques and spaced repetition mechanics to improve long-term memory storage and improve knowledge retention.

memoryOS is loved by thousands of people worldwide because it is a whole new joyful & game-changing approach for obtaining the most effective memorization skills for the brain while having fun.

Memorization is as important as reading and writing and should be taught as our base skill. Our goal is to make memorization skills the new norm by making them easy to obtain and widely accessible.

Erase all the uncomfortable “I don’t remember” episodes from daily life, control your memory, ace tests with calmness, and learn speeches, names, dates, trivia, and everything important while improving your brain health. As a result, you will become confident in your own abilities to remember under any circumstances or even become a person who has remarkable memory skills – a mnemonist.

With mOS, you will train and improve your brain with memory exercises and games:

Names, Long speeches, Lists of items, Birthdays, Personal facts, Passwords, Trivia, Languages, Vocabulary and phrases, Countries and capitals, Flags, Historical timeline, Numbers, Periodic table
Content of complete books, Dates of significant events, Complex data structures, Concepts, and figures

You will also train and improve your brain with the following exercises:

How to keep track of years, months, weeks, and days
Advanced study techniques, Spaced Repetition system
New Mnemonics Techniques
memoryOS is an online app that helps kids and adults focus, and provides brain stimulation through gamified training.

Why is memoryOS lightyears ahead compared to any other memory booster and training tools?

• memoryOS shows results after the first training session:

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 training session.

• Providing your brain with structured storage space:

We have spent 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 brain's storage space, allowing you to easily encode, store and recall like a 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 trainer. Actual improvements exceeded our team’s expectations.

• Gamified educational technology 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.

Enjoying the app but I've given a low rating as they have tried taking a full years subscription on 2 seperate occasions. Luckily, my bank blocked it! Is the memory champ getting greedy ??? I went back and checked my subscription. I'm definitely signed up to the student plan which is monthly payments so why are they trying to take the full amount. Fix this and you can have 4 stars.

Hi Dave, thank you for your feedback. Such a case might happen if multiple plans were selected during sign-up, which could explain the mismatch with your monthly student plan. We'd like to look into this directly. Please email us at support@memoryos.com so we can review your account and get this sorted.

I like the app—its techniques are helpful and well-designed. Some of the videos could be shorter, but overall the content is great. Unfortunately, I encountered a very disappointing billing issue. I was charged for the annual subscription on April 2. Then, I saw that another payment was already scheduled for April 11, which seems like I was charged a full year early. I had to cancel immediately. I hope developers solve this issue soon and let me keep access for the year I already paid!

Dear Nerea, we're truly sorry for the billing confusion and appreciate your kind words about the app. This isn’t the experience we aim to provide. Please contact us at support@memoryos.com—we’ll make sure your case is resolved and your access reflects the payment made.

What an app! The learnings start right away, it's very well explained and there are many exercises that get gradually harder (but are actually so easy with the techniques). I went from 1/15 (2 mins) to my pretest to 15/15 (1:30 min) in less than an hour. The mind palaces are really great and fun to explore, and I love how the app encourages you to remember the rooms at certain days to make sure it's in the long term memory. The price is a bit steep for me, but there are many plans to choose from
