Calculator is great and has all the features that are useful in everyday life, but there are few things that can be improved: 1) Light or dark mode settings. 2) Any boundary distinguishing between the buttons, like any square or circle around the buttons would make it more visually appealing, rather than the current floaty nature of buttons. 3) Ability to paste the copied numbers from clipboard.

I absolutely love the app. Guess the app is everything and more you could ask from a calculator. I just have 1 suggestion to make. In the earlier version I guess, when you toggle from normal to Scientific, you would get a blank calculator where we could do a different set of calculation without affecting the digits in the normal calculator. It was such a useful option. Please bring it back.

The edit feature of the calculator is very poorly designed. Instead of giving me " | " a cursor to edit, it gives a selection which is very annoying. It's very difficult and sometimes impossible to edit the way I want and I end up writing the whole thing again. In short the calculator app is very USER UNFRIENDLY when is comes to basic calculation. You have added so many features but forgot to emphasize on making some basic features easy to use.

By far my favorite app by Xiaomi and my favorite calculator app. It's very reliable and ad free. And the conversion tools are very useful for converting things like currency, length, mass, etc. My only complaint is that there isn't a square root button. Otherwise, it's a very useful app and the conversion tools make this calculator better than any other.

For anyone complaining there is no AC (All Clear) button, there was always only C (Clear) button. In the new version your calculations are saved automatically, so you don't have to repeat, retype or miss anything. You can clear these calculations by tapping on the three dots on the upper left corner, you then have two options - "History" & "About". Click on "History" - from there you can either press on the specific calculations to continue, or you can tap on the 3 dots again to clear history.

the march 11 update is buggy. after opening the app and leaving it open running in the background and switching back to the app will cause the app to fail to scale properly. the tabs to switch between normal calculator, converter etc will appear on top close to the status bar and they are inaccessible from my Redmi Note 6 Pro. i had to revert back to the old version by uninstalling updates... please fix this issue. on suggestions I would like you to add a programmer calculator.

I'm not sure why it desperately wants to collect information, but no. Also noticed that starting it as a scientific calculator and then using the mode button at bottom left removed the left column of functions (as expected) and also removed 0 1 2 3 and = (very funny) and removed the mode button needed to switch back (also funny).

They removed the option to press and choose from your history to make your further calculations fast and easy. Probably That was the only option for the success of this app. Now it is useless. Many good apps are there to choose from. Don't roll out such terrible updates. Shame.

A good calculator if you want to use one for daily basis and not the conplex one. It also has built in converter like money exchange or cm>m. So why 2 stars? Because it shamelessly asked to collect your info data.... Just to use the calculator. Even if you dont agree it'll keep popping up everytime you open. Makes no sense

The app is good but the only thing in my opinion which is missing is the M+, M- and MRC buttons, the developers can add a stirp with these options at the bottom on numbers row or at the very top.. I frequently use those options so it would be good if the developers consider my suggestion, overall the app is great. Do update

Really like this and glad I found it. Took a while to find a calculator app that delivered on the features I wanted to see. The only issue is that typing numbers in quickly sometimes skips the haptic feedback for some presses. Not a deal breaker and still gets 5 stars. Love the way the calc can become a floating pop-up--very helpful.

Thanks a lot to the people who gave their hand in creating & supporting this amzing app. The only issue I'd like to draw your attention is the history of calculator doesn’t work as expected. Hopefully you would solve this issue as soon as possible.

The best All in one calculator. One of the best apps which I've ever seen. Just a recommendation: try adding a feature to reorganize calculator contents like date, volume, length etc. It will be more convenient if I will be able to rearrange them based on my personal requirements.

Probably the best calculator app on the market. It has measurements for all different size and their conversions as well as option to convert different types money. Overall easy to use and super practical and offers a lot. One might even say everything.

This is not just a math calculator. It is a calculator of your life which says when you were born what age, loans, height, BMI, weight, date, data converter, discounts, area, mass, time, temperature, speed, mass, volume, length, numeral system, investment, and currency converter and much more. This is a great app but I think it's only available for Xiaomi, MI and Redmi devices. But this is a part of my life and this app is not just perfect it's an excellent app. Thanks very much for this app.

Very good, a calculator with lots of functionality—age, BMI, dates, currency, bills, interests and what not. It has made a great improvement ever since. However there's still one very important thing is missing. The Cursor Movement. There's no Cursor in Mi calculator. Just hope Mi adds it and this will be the best, complete calculator app for Android.

The update is worse and lousy. Previous calculations still can be seen and make the interface look cluttered. Basic calculators are supposed to be simple. They are not chatrooms where you need to search History button, click here, click there just to clear your old conversations. If I want to do calculations whereby history is involved, I would use a spreadsheet. What were you thinking when doing the updates?

Mi Calculator is not just your average calculator app. It has converter features that not many other apps have, and it still manages to rock a very stylish UI. Mi Calculator is definitely my favorite calculator app on the Play Store. My only complaint is that it doesn't have a dark theme. As people are becoming more aware at how the lights in our screens can damage our vision, more apps are getting a dark theme option. I would love to see that in Mi Calculator.

This calculator misses the cursor, which means you can't control where you input values/operations, i.e. if you want to put a parenthesis before your equation, you will have to delete the whole thing! Also, why does a calculator need to collect privacy info?

Ama. J. Dec 4, 2019     

Great extra features but it is not smooth as Google calculator 1) we don't have any cursor so if we have written something wrong so we are not able to go there and change it. 2)also provide extra features on basic calculator. We always have to shift for scientific calculator. Otherwise add a feature to remain permanent on scientific calculator page.

This is the best calculator in the world it is great . It is easy to use and every calculations are there in this application . It can tell the accurate date of birth . But only one problem is there that the ratio to the power calculations are not there but overall this app is best +-×÷........ No-one can say that this app is bad .

Ris. K. Apr 16, 2022     

Clean ui and great features, but why does it require to collect personal details for a calculator app,If I withdraw consent in settings, It keeps annoying me everytime I open the app. Please stop asking permission to collect personal details everytime we open the app. It's really fishy why a calculator keeps bugging people for personal details.

Mo. M. May 8, 2022     

I don't know why but I actually really like this calculator it has other features in it like mathematical equations like you'd be surprised some calculators now don't have pi also the currency exchange is pretty cool. I've literally never had a problem with a xiaomi device or any software that they have made.

Loan calc showing wrong values for balance, it should show remaining principal balance. Age calculator shows useful details about difference in dates in months, weeks etc, date calculator is useless no option to add days, weeks or months.

Jua. M. C. Jan 6, 2020     

This calculator app is really useful in terms of everyday usage: the addition of a currency converter, a split bill, and change between units of measurement. Nonetheless, something's bothering me: I'm an engineer, so having a good scientific calculator with me is extremely important, sadly, this is not the case with Mi Calculator: even though it does have logarithms, exponentials, factorials,etc. n-roots, and even "π" are missing. Extremely good for everyday users, not so good for heavy users.

SRI. S. Dec 9, 2020     

App looks simple and basic... Conglomerate of both primary and scientific calculator... Comes in handy whenever real calculators are physically absent. In concrete terms, it is perfect 💯... If possible, please remove the Calculation History part... That may be sometimes an obstruction... No adds... Inbuilt in Realme... A must-install. 😊

At first my exchange rate updated and stuck at 06 Feb 2021 don't know what happened.. then I was trying to fix it by clear cache, clear data and try to uninstall it.. the problems still the same, and right now I'm stuck at 10 March 2016.. what the hell man.. it was so annoying...

Pra. S. Oct 13, 2018     

It's the perfect calculator app. Gives many conversations and also currency converter. I used it on my previous mobile. But it crashes when I open it in my OnePlus 6 and I don't know for what reason, may be tall aspect ratio. Please make it compatible.
