### 5/5 — 键盘数字0能不能别放在最左边了用的恶心

*2026-07-05*

以前就是下中更新变成下左边扭

### 4/5 — 功能整体不错，有一些产品建议希望可以考虑

*2024-04-08*

产品建议：
1、加减乘除符号也可以自定义删除
2、增加自动计算汇率的功能

### 4/5 — 候选框框计算

*2023-05-01*

怎么设置在候选框显示计算过程？ 如果没有希望增加

### 5/5 — 最近是出现bug了吗？

*2023-01-10*

以前挺好用的，现在总是出现错误乱码

### 5/5 — 有个问题

*2022-09-03*

能不能设置一个一键删除？一个一个删很麻烦啊！ 还有一个，在进行计算的时候能不能如科学计算器那样，这个虽然也能编辑公式，但是只能通过括号来确定运算顺序，式子一长就看上去很费力，只能进行简单的运算。 当然，如果开发起来比较困难的话当我没说。
补充一点，iPad无法使用。

**Developer response:** 好的，收到

### 5/5 — 作者大大不维护了么

*2022-05-09*

好像很久没更新了，呜呜呜，感觉要被弃了

### 1/5 — 计算器

*2021-11-20*

在聊信聊天对计算才完美，戓和小米那样小窗口才好用，浪费了6元

### 4/5 — 能不在输入框显示计算过程，只显示结果吗？

*2021-11-03*

能不在输入框显示计算过程，只输出结果到输入框吗？有些输入框限制了只能输入数字

### 5/5 — 键盘坏了

*2021-10-04*
