### 5/5 — memorizing pi made easy

*2026-02-25*

been using this app for about 2-3 years now and it’s been an absolute luxury for me. i use a mind palace to memorize up to 4500 digits and this app helps me practice. i know it’s a niche skill but i wish more people would practice memorizing large sums of numbers like such, it helps in more aspects than one might originally think. thanks for the app.

### 5/5 — 好

*2025-08-03*

这是一个很棒的软件，小孩很喜欢，小孩在家不无聊

### 1/5 — have to pay money on a paid app

*2025-02-10*

I paid money for the app, and the ads pop up over the full screen and take several seconds. and I have to pay EVEN MORE money to get rid of ads. completely absurd.

### 5/5 — Great

*2024-12-28*

This is a great App for memorising PI. The ads are occasional enough to be un-intrusive. Only one thing that could improve my own experience is making it so you can enter more than 2000 digits at a time, though I appreciate this won’t be an issue for most….

### 5/5 — Memorize Pi

I Wish You Could Go Up To 
6.519e+264

### 3/5 — "Purchased Before" option doesn't work.

*2024-01-16*

Purchase restore just hangs and never completes.…for that reason it really should be a 1 star — consider the 3 stars a generous gift.

### 5/5 — hi

*2023-11-27*

hello i have memorised 9,000 digits of pi now this app is good

### 1/5 — Poorly designed, must pay twice to remove ads

*2023-09-29*

You have to buy the app, then pay a few more bucks to remove the ads. I’d forgive that but the app is very poorly designed. For instance in training mode it lights up the next number.  As another reviewer pointed, how in the world is that helping me learn? I don’t want to have the next number shown to me!

There are no app settings. For instance I don’t want to hear a ridiculous bloop sound every time I press a number and don’t want to have to turn the volume all the way down so I don’t.  Nor do I want to see four question marks across the top of the screen the entire time I’m playing! I could go on and on. 

The only thing the app has going for it is the ability to start playing x number of digits in. For instance if you’ve learned the first hundred digits by heart you can start at 101.

### 3/5 — Paid three dollars, still has ads

*2023-04-27*

This same app is free on Android. If I pay money on an app I want it to be ad-free, because it is not ad-supported. It is user supported.

### 5/5 — Super helpful

*2023-03-17*

Perfect layout, perfect practice mechanic, great app. I would only suggest a page to generate digits of pi up to the user’s choice and a way to start from a certain digit. Other than that, it’s a great app
