### 5/5 — Very good I like it

*2026-08-29, version 1.5.7*

Hi

### 1/5 — Only option was to get scammed out of $300

*2026-08-28, version 1.5.7*

Was never offered an option to try this app free, which is fine, but then I was presented with the usual yearly or monthly option and I chose $25 monthly to try it out, not realising it was a 12-month commitment tor $25 payments even if I cancel after one day I’m on the hook for $300. Ultimately it’s Apple’s fault for enabling such a scammy option but developers shouldn’t take advantage of it as it preys on customers that don’t read the fine print.

### 1/5 — Buyer beware!!!

*2026-08-27, version 1.5.7*

You’ll sign up for a free software four days and then they’ll charge you $4.99 for a basic annual plan. A month later they’ll charge you $149.99 for an expert annual plan.  I’m in the process of disputing both.

### 5/5 — Fun and immediate results

*2026-08-27, version 1.5.7*

This app and the lessons have been fun to do and I’ve have been able to implement the techniques immediately and see results. I can’t wait to see how far I can take these new memory skills.

### 4/5 — It works

*2026-08-25, version 1.5.7*

I’ve had challenges remembering names. This app has tools and tips to help remembering names and lists. Have fun.

### 5/5 — Finally!

*2026-08-24, version 1.5.7*

This is the best app I’ve ever used.  The content is excellent, the goals are pure, the simplicity is elegant and respectful.  I loved Moonwalking with Einstein and have been familiar with the mind palace for a while. Despite my pre-exposure, I have failed to become disengaged from the masterpiece this is.  

Congratulations Jonas, Bravo.

### 5/5 — I wish I had this app years ago.

*2026-08-24, version 1.5.7*

"It is the best thing I ever learned, as it opens a whole new world, as I can see many applications. You're a great teacher. I am finding it fun and rewarding

### 2/5 — Confused

*2026-08-24, version 1.5.7*

I’m  really confused as to what I’m doing on this app!  Is this just a silly game ?

### 5/5 — Effective and fun!

*2026-08-24, version 1.5.7*

I like this app. Mostly I like that I don’t even really have to use the app to use the app. 

I’ve made a habit of memorizing random stuff now for fun, but Jonas’s videos have helped work up to that.

### 5/5 — Memory practices

*2026-08-23, version 1.5.7*

This is gonna be great!!!
