### 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.

### 4/5 — Efficient

*2022-01-25, version 7.00*

I consider this app great. Is simple and effective. Some stuff could be done slightly better but overall it’s great.

### 5/5 — 不錯的遊戲

*2021-06-21, version 6.03*

這個遊戲真不錯，第一次遇到可以記到100萬位圓周率的遊戲，光是一萬位就已經很扯了，感謝這個遊戲，現在我已經記到100位了 ^_^

### 5/5 — 非常不错的圆周率记忆软件!

*2021-03-13*

要记忆上百位、上千位的无理数，完全靠机械记忆是不容易的，在记忆过程中，自觉不自觉地要用一些记忆数字的方法，而且很可能找到一些自己独创的方法。这种方法的运用和创造记忆方法的能力是有普遍意义的，是脱离圆周率而存在的，会记忆别的内容时表现出来。所以，从这个意义上讲，即使具体的数字忘记了，但学会的方法和锻炼出来的能力并没有消失，会融入自己的总体知识和能力之中。背诵一段时间圆周率以后，自然而然地会对数字有比较高的敏感性，见到数字就想记忆。如路遇汽车就想记车牌号，看到或听到广告节目中的电话号码就想记忆等。

### 5/5 — Great! Will there be more options?

*2021-02-18*

Love the layout and study mode! Hopefully there will be other constants to memorize soon. Like e, phi, and tau.

### 5/5 — Poor for learning pi

*2020-12-11*

Ads at bottom, which can be removed with additional purchase. Training for pi is not good, next digit is given to you, you do not have opportunity to recall number and get it incorrect, i.e. train. I would not recommend. Have purchased other pi apps that were superior to this one. Not worth your time nor money.

### 5/5 — Absolutely amazing for memorising Pi

*2020-12-10*

It really helps you to learn all the digits. I have been doing it a couple days, and I have already learnt 70 digits of Pi. Very well made app, and I do recommend If you want to learn Pi!

### 5/5 — Great

*2020-09-24*

In just three hours I already know 46 digits, it’s fun actually

### 4/5 — Removing ads still leaves the annoying square

*2020-06-06, version 6.00*

Paying for an ad removal should actually remove all of the ads, even the non-intrusive ones. Please remove the square in the lower-left corner.

### 5/5 — 超级差劲

*2020-05-24*

小数位不对，望改正

### 5/5 — 我特别喜欢背圆周率，才下的这个游戏。我现在用它已经背到256位了。

*2020-04-14*

内容也很好，现在我背圆周率越来越快了。大拇指赞👍

## Most critical reviews (10 lowest-rated)

### 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.

### 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.

### 1/5 — Crashes

*2021-10-06*

The app crashes just at launch.

### 1/5 — 起動できずおちる

*2021-06-17*

起動ができませんので修正願えますでしょうか?

使用環境は
iPhone6 iOS12.5.3 です。

使用環境が古いからと言われたらそれまでですが。。

### 1/5 — 软件有bug

*2021-06-13*

根本打不开，进去就闪退

### 1/5 — 垃圾

*2018-07-23*

收费大家别买，免费大家看看

### 2/5 — "Purchased Before" option doesn't work.

*2022-09-13, version 7.00*

Purchase restore just hangs...

### 2/5 — Needs jus a little more for 5 stars

*2022-03-16*

Needs just a few features for me to give 5 stars. I recommend making it so you can slide back to see what you’ve already typed when doing the challenge. practice mode should only highlight the number to push once you make a mistake. Conclusion, this app is fine if you want to learn pi but it’s not as efficient as other ones I’ve used. Good luck👍

### 2/5 — Pi digits lay out

*2021-05-30*

When I used this app a few years ago, each row had five groups of five digits. It’s great that you can adjust the number of digits per group, but you have no control over the number of groups per row. They should add this capability as everyone has different preferences that help with individual memorization needs.

### 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 — 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

### 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

*2024-03-09*

I Wish You Could Go Up To 
6.519e+264

### 5/5 — hi

*2023-11-27*

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

### 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

### 5/5 — Genuinely surprised with the app and myself

*2023-03-15*

I memorized 100 digits of pi over three hours and I cannot believe how easy this app made it

### 5/5 — Genial

*2022-10-13*

Me encanta que tenga cronómetro y te puedas retar a hacer tiempo por ejemplo con 100 dígitos, por ahora tengo de record 28 segundos los 100 y es un vicio intentar mejorar

### 5/5 — Neat little app

*2022-08-20*

Quite frustrating to change where I begin tho

### 5/5 — RTA

*2021-11-08*

This is great for learning pi!
But I want to play RTA, so I want the time to two decimal places. for the time.
