## Calculator Smart Reviews in United States

### *---- "Bad Math??!!?"
Unfortunately, this calculator can’t do math… and as that’s the only thing I need it to do… needless to say, it didn’t work out.

617.14 minus 602.45 does not equal 14.689999999

Close, but not close enough.
-- 3849215607, 2022-09-20

### **--- "Works Great, But the updates!"
I cant tell if this app updates more than the news or what! Seems like theres always an update daily, and it's the same version every day! What gives?
-- Addy's, 2022-07-30

### **--- "Enter key doent work - Not for MAC"
How did the app developers miss the very basic feature of enter key while working with Mac keyboard.

May be designed only for mobile devices
-- Murthy VVVS, 2022-06-14

### ***-- "Rounding issues on M1 Mac at least"
I tried a simple calculation:

177 - 170.21 and the result was 6.789999999 -- the correct answer should've been 6.79.

I can figure it out, but iti's more difficult than it should be.  I might be better off typing my math problem into google search box which gives the right answer.
-- RobertW42, 2022-04-21

### ***-- "It works but..."
It does the calculations as expected, but I was quite dissapointed to find that there is no Back button for those of us who make mistakes entering data.
-- RobertJProgram, 2021-07-12

### **--- "some expected keys do not work"
I would expect ^ should work as power, but it is not recognized. Just this fact alone makes it difficult for me to use this calculator.
-- user_passing_by, 2021-05-03

### ***-- "It's just okay"
This is just an okay calculator.  It works fine, and you can use your computer keyboard to enter numbers etc...  Having no preferences is negative, I mean really give the user some preferences to get full potential from this app., even the free version should have preferences.  Lastly, were's the tape/history/paper strip, so the user can see the list of numbers/calculations entered and done, again, even a free version should at least have this feature.
-- Kalawina, 2021-04-29

### *---- "Poor Display"
Can’t see the digits in display completely. Maybe because of banner add at bottom. Can’t make calculator smaller in hopes of seeing complete display of digits.
-- wdyhxsid3639, 2021-04-28

### *---- "misleading"
It's advertised as if this calculator gives an exponent option. Not true
-- mis-leading, 2021-02-13

### ***-- "One quirk for keyboard junkies"
It's well designed, but it doesn't allow the "enter" key to be used for "equals" on my external number pad (a Rottay 22-key mechanical numeric keypad), which is weird, because even in a text box, the "enter" responds exactly like the "enter" on my 10-keyless keyboard. Since there's no good way to natively map keys on numberpads, if you're using a keyboard without a number pad and spent the extra money for the external one, just know you will either have to adjust to using "=" or use the "enter" on your regular keyboard.
