### 2/5 — Does not explain everything

*2024-08-22*

I paid for the app and sections like linked lists for example only has code and pseudo code for only one type of a data structure. Please update all data structures to include all psudo code and c++ code. Then I will change my review to a 5 star.

### 4/5 — Wish it had dark mode

*2023-09-22*

On ios im able to make a singular app dark mode via "smart invert", but not on macOS

### 4/5 — 做得还不错，就是内容少了些

*2023-04-20*

可以一步一步的看代码演示且每一步都有图像化展示对于初学者来说挺不错的，只是内容少了点只有一般常用教材上的内容，期待可以增加更多内容。

### 4/5 — Diggy

*2023-01-03*

Great

### 2/5 — Grammar and spelling poor. Most content locked.

*2022-10-24*

Imagine trying to sell freely available data for $3 by locking 90% of the data structures behind a purchase.

### 2/5 — 要钱18块钱

*2022-07-06*

做的还行需要的人觉得好用。我觉得没啥用，而且就一点，不支持自定义。

### 3/5 — 节流

*2022-03-25*

大部分收费功能，忘记那个网站也有了，全部免费的就是英文的而已

### 4/5 — 很好

*2020-12-02*

很不错，不过在C++代码中能否加入注释呢？，四星激励一下作者。

### 5/5 — 非常实用

*2020-07-15*

太棒了

**Developer response:** 多谢好评

### 5/5 — 有意购买了，希望更加完善。

*2020-06-08*

一个问题，新版本会重新收费或者加收费吗？

**Developer response:** 不会的，可以放心购买

### 5/5 — Hello

*2020-03-16*

I would recommend this app for anyone that is trying to get into computer science technologies

**Developer response:** Thank you very much. And I will make it better.

## Most critical reviews (10 lowest-rated)

### 1/5 — Bad

*2025-04-25, version 1.8.1*

Purpose for earning money not for education

### 1/5 — Waste of time

*2022-12-14, version 1.8.0*

Paid app

### 1/5 — Not valuable

*2022-04-19*

Too little info for a $2.99 app

### 1/5 — Garbage

*2021-12-29*

Trash, if you will

### 1/5 — Run ads if you need to

*2021-11-12*

If you need revenue, run ads. Don’t lock almost all the structures and ask for 2.99 when we can just google and get the same information for free. This is a pointless app if you require payment to see a simple stack or queue overview.

### 1/5 — 90% of app is behind $3 paywall

*2021-04-20*

You’d be better off bookmarking GeeksforGeeks pages as they’re much cleaner than this app and it’s free

### 1/5 — every two seconds asks for a review

*2020-11-18*

here is a review of that, enjoy

### 1/5 — Overrated app.

*2020-08-27*

Overrated app

### 1/5 — 拖拉机与宾利

*2020-01-14*

开源软件是拼凑出的拖拉机。商业软件是宾利。这个破拖拉机想当宾利

### 1/5 — Really bad

*2019-12-15*

$2.99 for bad info. One sample problem had the answer start with “A circle of 30 people in the prompt inspired us to use a circular linked list”. For this particular problem a candidate using a simple array would be just ok, but a linked list, and particularly a circular linked list would not pass on this. Outside of data structures, a single 32-bit int could pass for tracking 30 people, but reality is that all you need is a single byte to track the positions that you do/don’t want in the answer and a count of people considered so far. Perhaps if other info was better I’d give a better rating, but I’m not paying $3 to find out that I’ve been robbed.

### 5/5 — Super useful for studying DSA.

This is a great app and definitely worth supporting the developer! The interactive parts and pseudo code are absolutely excellent.

### 5/5 — Amazing app

Very helpful

*2024-10-17*

The app is good, but has only cheatsheets, no exercises.

### 5/5 — Simple and Effective

*2024-05-01, version 1.8.1*

The app is really good way to show how these basic building blocks in computational theory are put to work.
This is a good tool for research advancement as it allows one to look back in time, re-organise our thinking and plan ahead with something new.
