Solid app that could do with a few enhancements
Solid app though a bit over wrought for its intended purpose. Ad-free cost is also not clear as it seems purchasing on Mac App Store does not provide IOS version ?
天天计算器
不是很好，不会列方程和解，不好 你……
WEIGHT Conversion
1) My unit converter does NOT show weight conversions: why? 2) 11/25/25 Suddenly keys started making sound when i type numbers. I don’t want sound and don’t know what to do! Do you check these notes?
Great Calculator
This has everything I need, all in one calculator. Excellent job on this one.
无法更新-前期已购买会员
昨天突然无法更新；前期在程序内已经购买了会员；现在重新卸载安装，提醒；“无法安装”严重投诉！退钱
广告太多了
计算器底下老有一个广告特别烦，特别烦，而且他就是设置一下只有几秒才能取消广告，剩下几秒他照样给你发广告，就是有点烦，就希望这个广告给你发了，就是别发了，我觉得这个还是蛮好的。

アップデート出来ない
延々とアップデートを繰り返していますけど、なんでしょうかね？
Day Calculator
I love this calendar and I use it often.
？？？
一直重複更新動作
不错
看到很多计算器都要付钱，这一个就全部免费，👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻但有好多广告😂
看廣告沒有解鎖主題10天
看完廣告有解鎖主題，但是退出app後再打開就說主題到期了。進到設定查看又要看一次廣告，點選主題進去又再看一次廣告，整個操作過程一直在看廣告然後我的主題依舊沒變

Good app with a weird feature.
This app is really good for doing calculation personally and choosing themes. But there has a weird feature in conversion thing. But we are okay to do it.
不怎么样
广告多且影响界面美观，而且复杂的功能一大堆，个人主观感觉不怎么样。
用了好多年，结果突然不能用了。
一点软件就闪退，卸载重下载也不行，为什么？
有问题，请修复
一直用这个很好用，为什么今天不能输入5位以上的数字，输入4位，再输第5位数就变成个位数，删除重新下载也是这样，怎么回事？
可以改进一下就更好了
就是计算界面下面有个其他app碰一下就跳转了让付费下载
Calculator
I like this calculator
广告推荐超级不喜欢
能把广告推荐给我别推了行吗，不小心碰到真烦人，其他的超级棒
不错
相对来说比较好用
Не правильно считает %
Калькулятор не правильно считает %, посмотрите в Калькуляторе от Apple, как привильно должен считать %. И исправьте.
还行吧
还有点广告的哈哈哈哈
Clara
Easy to use clear just a few glitches in it
2分鐘就彈廣告，
彈你嗎個批⋯⋯
挺不错的
有点儿回忆小时候的真人计算器但是希望你加上竖式计算
見た目は良いよ
広告が下段に出るだけなら良いけど 全面にでるとか削除対象だね
Beste App
Super 👍🏻
Easy to Use
Like this app, easy to use.
計算機缺鍵
ENG呢？
its pretty good
It works well, but i would love a paid for version where it allows you to change the layout of the calculator, ie. move the functions buttons from left side to right with the calculator numbers together. Also, Allow for notes to show on the main screen instead of clicking on it to find out what that calculation was. Also, allow to email the whole calculation history instead of the one you touch.. still an ok app for me.
刚觉没以前好用

Day Calculator
Great
Ads Ads Ads and them more Ads Ads Ads
If you like being forced to see full screen ads this app is for you. Me? It’s Delete DeketecDelete
好啊
不错啊
閃退...
更新後，計算機完全打不開 使用的手機是iPhone XR
Great I like it
The notes are good to remember why you made the calculations so you refer back it to it later to do another calculation based on one previously
Очень плохое приложение
Как так что когда 1000*10%=0.1 это не правильно правильно 1000*10%=100
Apple Watch
The layout is nice enough, I like having all numbers and simple operations with individual buttons. The problem is the buttons in the calculator are laggy or not sensitive enough. There's a fine line between pressing hard enough to activate a button and starting the force press menu. It's hard to tell if a press "took" because it takes a second to register and display. I do like the force press offering a tip calculator, which is my main use for this app, as there are quicker calculators for simple math.
仲有進步空間
不能五個位數字
5 Stars
Easy to use and stable.
Apple Watch Review. Don't bother
This is zero stars. It never even started on the watch. Period.
good
good to use for calculator
굿
굿
