ChampCalc Scientific Calculator for Android
The best calc app I've used.
I really like this app but... Why there is no result when I calculated sin negative(4sin120°)? Am I wrong? If yes pls help
I love this app for it is really functioning well. However I am unable to find the shift button
Very good and helpful application... But the vibration when hitting the keys is very annoing.. How can I stop it?
It calculate wrong .. it says 10/2(5)=25 when the answer is 1!?
Nice app, but can you add engineering display and value entering, for example 3k(kilo entered say by pressing shift+6) and the result shown as 3.45K
I hope it will support hex, bin, oct, and other notations, and allow conversions between them.
Nice Interface, Nice Work. Well Done
Thank you...now this is my Casio
Thanks for developing this...:)
Mind blowingly user friendly, accurate and ultra fast.
Bah bah
Thanks!
Good one
Nice app, beautiful presentation. Mimics the good old college calculator!
NO FLAWS...WHATSOEVER
Fantastic app for calculating. Thank you
Very good calculator
Perfect look and feel. It works my old, lovely scientific calculator. There is only one issue: on older smartphones like Samsung Galaxy S3 Mini it can't detect quick taps. I have to tap calculator buttons moderately.
The features and customisation of the free app are great. I'm not a scientist or a budding mathematician so... this calculator does all I need. Thanks.
Uh, permission creep sets in, no reason given in change log. A great app, previously needed no permissions at all, which was a bonus.
Great App
Good
Low factorial limit. I do a lot of factorials. My go-to app can perform 6000!, but this app is limited to 999!. Not a deal-breaker if you don't do factorials (or very large ones). The app seems nice, but I'm gonna stick to my go-to fave sci calc app.
Most useful for engineering
Useful app
I needed a scientific calculator that does all the jobs including unit conversion and show the expression mode. Most others that I used did so, but after sometimes expression mode is gone. Or they show many ads. But this one is different. One suggestion enable Vinculum option for repeating decimal numbers. Thanks.
I can not multiply -1. Says invalid use of operators. Like (3+4i)×(-1) is rong in calculator.
It says 'designed for phones' but it works also on tablets. I have installed it on Samsung Tab S3 SM-T825 and works very well. I don't need a scientific calculator but I will keep it just in case. The beautiful part is that there are NO ADDS ! It works only on portrait mod but I don't mind. Maybe in the future will be possible to change from portrait to landscape. I give it a 5 stars. Good job.
Great app
The best calculator app I've seen!
The lack of ads in the free version and the amazing screen layout make this the best calc available - I will pay for the Pro version even though I don't need it!
Great app. Only thing missing is a widget.
Simply amzing and very useful
It's good
A very good app with an intuitive layout
Very nice calculator
It's good

By the way, is it possible to DEACTIVATE button Vibration upon press? It eats my battery like crazy due to Vibration in each input, especially for long time usage. Damn the new version eventually better. Less confusing for Options button
