数字加粗
差评
莫名其妙跳广告 还×不了
关于语音按键音问题
按键音不能调大调小
购买了移除不了广告
为什么我以前购买了，移除不了广告啊
广告多
广告有点多了
希望让安卓手机也可以下载，非常好用和需要
挺好
百分号不能计算
百分号无法计算
能不能实时显示计算结果，
使用体验都不错，就是看不到实时结果。
有问题
啥毛病啊，相减都是0
希望增加的功能
希望增加历史记录功能，有日期
讨厌广告，关不掉
广告好烦呀，有个回收站就更好啦
不能实时显示等值
比如12+13+45+89=159，再＝前面随意修改后，＝后面的数值就会跟着改变
好用，还能再改进就更好啦
平时用来比较用的多，因为能备注还能直接看到历史记录。最近双十一，看的东西比较多，如果可以保存备注过的计算，或者单独有个按钮可以筛选只显示备注过的历史记录就好啦。不然往回翻太多了
逻辑错误
历史记录竟然无法把结果二次相加，希望改善
添加信功能
希望可以添加一个删除单条记录的功能
求和
为什么相加得数都是0

%号不能用
如题，请检查
在输入区连续加减乘除，最前的数字已经看不到了
在输入区进行多个数连续加减乘除计算时，最前的数字已经看不到了，希望在输入区显示全部的数字
有广告
挺好用
我想知道为什么这样说什么东西就是那么容易满足员工要求自己和人相处方式进行调查……
我们可以理解你们之间关系的问题……
未经允许擅自扣费
点击设置，移除广告，没有任何提示，移除广告需要扣费。结果支付宝来信息说扣了48块钱，太坑了。
Missing star
You guys need to make a long math problem editable. Example being: 30000+(80×20×0.4×50)+(60×13×0.6×50) = 85400 I don’t have to rewrite the whole thing to make a small change! Thanks
bug
302÷303居然等于1？
无法付款
无法购买
得数问题
算式的得数在未按等号键时也能看到就好了。
很好用
好用是好用，但显示的小数点后的数字太少了 而且有广告，要是去广告得花45块钱
加项目
有汇率换算更好
Surprisingly Amazing!
Very cool calculator. Well thought out and fast. I really like the clean modern look. Well worth the money. One small suggestion. It has decimal digits for 3 and 5, but not 4. In my line of work I need 4 digits. Please add this feature.
差评
差评 自己会四舍五入我要的是正确的数字，四舍五入我还用你啊
横屏
希望作者大大能加个横屏的模式
三角函数计算用角度吧，孤独真不实用
如题
This is the best !!
Everything from interface to look and feel this calculator app is the best .. it solves everything seamlessly that you throw at it ..
没以前好用
真心没以前好用
Like but...
I really like this calculator. I like that it prints out on top what I am calculating. I would like if it allowed me to go in on area and at time of entry and what it is for eg. Breakfast 2 eggs 120 C 8:00 a.m. Or Shopping at Dept store ..2shirts $10 etc. Something like that.
备注没法用了
现在无法输入备注的中文字了
Like it!
Needs to have the plus,minus, equals buttons in a different position. Love the history and ability to use the history for current equations.
函数算来不对
错误的函数
Works great, but take your time entering data
The only reason I didn’t give 5 stars is that it can be a little slow causing a digit to mot get entered if you don’t take your sweet time entering the data. If you watch a little carefully, it works like a dream, but I think it could use a slight revamping to make it speed up input a little.
Could be just what I need
but it doesn’t calculate, all answers are 0
Love it!
The only calculator app I will use. I love that you can personalize it and it has a great design.
出故障了，不论什么运算结果都是0
糟透了
