### 4/5 — Jetzt ok!

*2021-02-04*

Nach Info durch den Hersteller nun mehr Klarheit. 

Leider sind manche Fehlermeldungen wenig aussagekräftig, aber die App scheint ziemlich gut zu sein. Man muss sich wohl nur in die Bedienung hineinfinden.

**Developer response:** Rechts oben auf dem Bildschirm befindet sich eine Taste namens "Berechnen". Bitte drücken Sie diese Taste, wenn Sie etwas berechnen wollen.

### 3/5 — A trouble

*2020-12-19*

Why can not I use the “∑”？

### 5/5 — 一点建议

*2019-07-23*

作者可否让积分结果带上更多的特殊函数或者常数

### 5/5 — 函数图形最好的计算器

*2019-07-13*

给孩子教学用的，免费版本包含了必要的功能,最主要没有广告。二维三维图像轻松实现。

### 5/5 — 关于变量取值

*2019-04-28*

如果能对变量进行取值限定，然后给出对应图像就好了

### 4/5 — Excellent APP!

*2019-04-15*

Only four star for there's no Chinese version.....Fairly hard for Chinese user to fully explore the app's function.

### 5/5 — Please add the Chinese version.

*2019-04-14*

My English is not good. It's too inconvenient to use！

### 5/5 — 好用

*2019-04-03*

真的好用，贴在笔记中

### 5/5 — 优美的数学学习工具

*2019-03-29*

一款很好的数学学习工具，能够满足常见的数学运算。有在线帮助文档，不懂的话可直接查看。无广告，就在手机上运行，不需要网络或云服务。就是免费版和付费版的功能有很大差别，这个能理解，毕竟开发人员付出了辛劳和时间，收取报酬是应当的。推荐数学教育者使用这个产品，估计能让学生提高数学的学习兴趣和水平。赞一个👍

### 5/5 — 哭了

*2019-03-19*

天啊怎么求积分啊！！！我要哭了！
how can i get the answer from a calculus calculation！
😭😭😭

**Developer response:** Please contact us via https://pocketcas.com/contact.php so we can help you with that. Thanks!

### 5/5 — 很不错的软件

*2019-01-17*

真的很不错

### 5/5 — Math that works the way people do

*2018-10-25*

This useful math program is styled like working on a sheet of paper. The key advantage is that, unlike working in a calculator app, when you're done you can have something printable that makes sense. If you use it more than a little the app can benefit from a keyboard. It reminds me of MathCAD by MathSoft from the 90's (sold to PTC, 32 bit Windows only.)
   The free version of this app doesn't do some of the more complex things that a working engineer or engineering student might need, but for anyone else its complete and there really is enough to work with to decide if its enough,

### 5/5 — 大家的软件都是全程德语的吗。。

*2018-09-20*

怎么调语言啊，英语也行啊，德语太痛苦了

**Developer response:** Hi, please change your language order in the iOS "Settings" app. English should be above German in that list.

### 5/5 — 很多英语看不懂啊

*2018-05-21*

不少的英语看不懂。 倒是挺好用的

### 5/5 — Comment

*2018-05-15*

I am an engineer! But I am now celebrating my 90th birthday. Big deal! I am still enthralled with the fact that I can still figure things out. And numbers matter, so with your help, the things that I design still fit together and work.

Muchos Gracias,

Joe Baumoel

### 1/5 — Broken App, Also wiped existing document with update.

*2019-11-28*

Enjoyed using this app extensively, however recent app update broke functionality - constantly crashes when loading my old work that worked fine before update. No debug or feedback to tell you why it crashed.

**Developer response:** Hi, sorry that you are experiencing issues! In particular, PocketCAS should never wipe your existing documents, but iCloud problems can do that. Could you please reach out via https://pocketcas.com/contact so we can help you resolve this issue?

### 1/5 — Limited - Calca a better app and free

*2019-10-24*

This app is limited and expensive. Another free app, Calca, is far superior.

### 1/5 — 壊れたか

*2016-11-27*

アプデしたら頻繁に落ちるし、英語がフランス語になり読めない

**Developer response:** Hi,
If the app switches from English to French, this means that you have set the French language higher than English in your iPhone's language settings. To fix that, please have a look at https://bit.ly/applanguage.
If you need any more help, please contact us via https://pocketcas.com/contact.php.
Best,
Daniel from PocketCAS

### 1/5 — Aaaaaaaah

*2016-05-19, version 3.8.1*

No no no , get Desmos . This is just bad. You have to hunt around to even enter anything. Get Desmos. I can't give no stars

### 1/5 — All

*2015-12-29*

日本語にして欲しい

### 1/5 — 使いづらい

*2015-12-25*

全然使えない 
やめた方がいい

### 1/5 — Terrible

*2014-02-06, version 3.4.4*

I tried using this app to help with my university calc homework, but it won't plot the functions I need except the most basic ones like x^2. Anything else it just tells me "could not plot the function."

### 1/5 — Broken

*2013-10-07, version 3.4.2*

Read update info AFTER clicking update button.  Was hoping to see speed optimizations or new features, but was very disappointed to read it was a compatibility update for iOS 7 that breaks compatibility for iOS6.

### 1/5 — Attention Arnaque !

*2013-07-05*

L'application affiche une pub et si par malheur vous effleurez l'écran à ce moment elle appelle un numéro surtaxé. Apple devrait rejeter cette application le plus rapidement possible.

### 1/5 — Doesn't CONVERT measurements

*2012-12-20, version 3.1.1*

I had originally downloaded this app to do measurement conversion (grams to ounces, kilograms to pounds, inches/feet to cm's & meters, respectively). It can help with advanced calculations (think trig or calculus), and has a function that includes SOME of those measurements, but DOESN'T CONVERT them. Useless to me for what I need it for. Deleting.

### 5/5 — Die App ist super!

*2020-09-20*

Für alle die nur einen Graphen darstellen wollen oder etwas zu berechnen haben, ist die App vollkommen ausreichend, besonders auch weil sie kostenlos ist.

### 5/5 — Good!

*2020-03-07*

Who can tell me the function formula of the last page?
Thx!
