Warning about subscribing to this app

Warning about subscribing to this app. You believe you are signing up for £4.99 a month. Only after you have set up your subscription (and with some digging) are you informed that after the first month this automatically increases to £14.99/month or renews for the annual plan at £149.99. Very underhand and dishonest. I cancelled immediately. A real shame as the reviews look good.

Hi Helen, and thank you for your feedback. We're sorry for any confusion, but we'd like to respectfully clarify what happened here.

All pricing and renewal details are clearly shown before any subscription is confirmed, and Apple requires explicit user approval before a purchase goes through. There is no automatic price increase without clear disclosure, the plan type, billing cycle, and renewal price are always displayed upfront.

What's shown before you subscribe? When you select a plan, both our app screen and Apple's confirmation popup clearly state:

If you're paying £4.99 for the first month, followed by an annual subscription at the yearly rate;
OR if you're selecting the £14.99/month monthly subscription option;
The exact renewal terms and when you'll be charged.

You must actively confirm this information through Apple's payment screen before any charge can occur. This is Apple's standard process, and nothing happens without your explicit approval of those exact terms.

We offer multiple Premium Plan options in the 🛒 Shop section, each with different pricing structures. Our most affordable option is just 3.49/month when billed annually (plus applicable local taxes). Each plan comes with a 7-day free trial (if you haven't had one before), and the exact terms are always displayed before purchase.

Since you've already cancelled, you won't be charged further. If you'd like us to review your specific subscription details or have questions about what plan was selected, please reach out to us at support@memoryos.com with your account information.

We also want to mention that memoryOS offers a robust freemium version with access to many lessons, videos, and Virtual Mind Palaces, completely free, with no payment required. Our team takes transparency very seriously and ensures all terms are clearly presented before any purchase.

Best wishes,
Anna

MemoryOS is great! …

It’s great for helping improve memory and clearly explained. Good graphics and well thought ways to practice. I would recommend it and can try it for free initially.

As an actor

As an actor, youth motivational speaker, and retired world kickboxing champion, my brain is everything. I depend on it daily for creativity, clarity, and connection. Since using memoryOS, I’ve felt sharper, more focused, and more confident in my ability to retain and recall information. It’s like having a gym for my brain. I already train my body, now I’ve got something just as powerful for my mind. This program is fun, effective, and carefully designed. Highly recommend it to anyone who wants to strengthen their memory and mindset.

Within the first 30 minutes I was blown away!

Within the first 30 minutes I was blown away at how memory can actually be something fun and not something to worry about. Jonas' memory prompts are definatly memorable! No chance I am forgetting the top 10 countries by area now, or the first 50 digits of pi!

Great!

Instruction videos are clear and easy to follow, I am very impressed how well the memory techniques work. For now I have only tried the free version but am considering to take the student plan. I recommend this app for anyone that thinks they have a horrible memory, you don’t!

Hi Donna,

Thank you for your feedback! We understand how the introductory phase might feel slow or underwhelming at first. Those early lessons are designed to introduce the basic memory techniques gradually, such as placing a few objects in a room, so that users can build confidence and mastery before moving on to more complex palaces and longer sequences.

We know the graphics are simple at this stage, and the focus is on learning the method, not visual flair. Once you move past the introduction, the exercises become more engaging and challenging, and you’ll start applying the techniques to longer sequences and custom content.

Your feedback is valuable, and it helps us continue improving the learning experience for everyone.

Best,
Anna

Avoid

My Wife thought this would be good to try and is currently trying to cancel, this is proving to be difficult!
Very poor, misleading and money making. A 3 day free trial is not free as you apparently sign up for a direct debit which seems impossible to cancel, even though under British consumer rights, you have a 14 day cooling off period and right to cancel.

I feel like my memory has improved already and it was good to learn some techniques to improve it. It is also enjoyable to identify objects in the various rooms, knowing you are getting better at it each time. I would recommend giving this App a go.

Great job on enhancements

I have not used your app for a number of months and I was so pleased to see how much you have improved the navigation options as well as adding an additional palace. Great work! Can’t wait to see what you come up with next.

Hi Andrew,

We’re really sorry to hear that you're waiting for a reply.

We want to assure you that we do respond to every support request and never ignore messages intentionally. At the moment, we’re experiencing a higher-than-usual volume of requests following the holidays, so response times may be a bit longer than normal. That said, every message is carefully reviewed and answered.

In some cases, delays also happen because we’re unable to locate an account without enough details, or because our replies end up in spam or promotions folders. This can also occur if the message was sent from an email different from the one associated with the subscription.

Please reach out to us again at support@memoryos.com and include your review name, the email used for your subscription, and your memoryOS User ID (if available). Once we have those details, we’ll be happy to assist you promptly with any issue.

We sincerely apologize for the inconvenience and appreciate your patience. We’d truly like the chance to resolve this for you.

Best,
Anna
