### 5/5 — 很方便的計算輸入法

*2025-08-04, version 1.3.7*

可以直接用輸入法計算，還可以加上千位數逗號、列出計算式，非常方便

### 5/5 — 功能意见

*2025-07-22*

当在微信或者在一些其他软件，比如需要翻页才能看完所有的数据的时候，用这个计算有点不方便，因为一点回键盘，聊天界面就回到最后的信息那个页面，希望能增加翻页记忆计算的功能

### 1/5 — Löscht sich ständig selbst

*2025-02-09*

Ab und zu ganz praktische App. Aber seit Monaten löscht sich die App ständig von selbst, was jedes mal das ganze Tastatur-Layout durcheinander wirft. 
Einfach nur nervig.

### 5/5 — Great

*2024-08-10, version 1.3.7*

Great, very convenient to use, I will never make calculation errors again, thank you!

### 3/5 — Could be better.

*2024-07-09, version 1.3.7*

If it could adding more function as sqrt or exponential operators.

### 5/5 — Great app

*2024-07-08*

I have had this app for some time and all it does is get better.

### 4/5 — 希望可以有算式過程，不要等好之後只有結果

*2024-06-07, version 1.3.7*

如標題所述

### 5/5 — 問了客服才知道的功能

*2024-06-06, version 1.3.7*

好用的鍵盤
問了客服才知道，按左上角的按鍵可以選擇保留輸入的算式或是只輸入答案～
分享給大家☺️

### 2/5 — 希望留有算式+結果

*2024-04-26, version 1.3.7*

只有結果還得重新打一次算式紀錄

### 5/5 — Dobre!

*2024-04-17, version 1.3.7*

Muszę powiedzieć że bardzo fajne. Zainstalowałem do testu ale zostanie na telefonie.  Szkoda że wynik zastępuje całe równanie. Wolałbym na końcu znak równości i wynik jak robimy wyliczenie w notatkach. Wtedy mamy pewność że wszystko policzone i nic nam nie umknęło.
