A simple and attractive UI It was the main reason for me downloading this scientific calculator over all the others that adopted a cluttered skeuomorphic aesthetic. One function that would be useful is the ability to view the calculations history.

Tasrif Rahman

God but There should be larger number, + - */% buttons. And the other e, pie, root over etc scientific buttons should be in another window. otherwise i'd give 5 star

Jorge Sepúlveda

Doesn't give feedback to user. I installed this on my G3 and it looks nice but nothing appears on the top screen when I try to use it. The buttons don't work at all.

Kirumy Yadav

On screen buttons overlay settings App looks pretty but the settings and themes button are covered by on screen buttons

Sinazo Lindani

It's a must have app if you're a student!!! Love it

K Dot

Why would I pay for anything on this app? The calculator isnt that good it just looks cool. Upgrade the backgrounds at give me a picture. gg

Abdullah Alam

Very Beautiful Tin... It's says it's a calculator and it does just what it says on the tin. However this is an exceptionally good looking tin. The default theme is great. My only suggestion would be to have a two line mode, so you can see both the calculation and the answer, as in most recent scientific calculators.

G Whit

Ok, but need to pay for decent backgrounds Ok, but not what I was looking for

Patrick Bell

It looks better than other apps It works well and doesn't look as ugly as other calculator apps

Ashok Beri

Desai Sanjay

Scentific calculator Nice love to use

Jack Watson

Ads in calc?

Deividas Kniazevas

Bad Design is nice but calculator by itself is really bad. It can't correctly do functions like acos, 0.5^2...

Sanyia Saidova

Beautiful design but there's a problem.. When you enter into immersive mode, the developers forgot to push the interface above the stock menu bar. This leads to the inability to access the 0 button or to access settings to exit immersive mode. Please fix and I will return rating to 5 stars as this is in fact my favourite calculator. If you can't, please include warning to prevent users from making the same mistake I did. Thank you!

Anantharam M S

Nice and appealing and quite user friendly both for normal use and mathematical applications.

Soumik Sarker

Sergey Smetanin

Memory doesn't work properly I can't multiply on MR value: 20*MR just shows MR value

Serg Sviridov

It's trivial calculator There is a very bad implementation of factorial. You should use long arifmetic to implement it.

Robert Sakanyan

Ahmed Saoudi

Too much ads Too much full screen — sometimes inappropriate — ads came with the latest update. And they popup ALL THE TIME. Converter not much useful since most of the conversions must be paid for. In uninstalling this right now.

Rowan Haines

Rubbish It keeps saying the app isn't licensed and then turning off

Prem Shah

Arlindo Coelho Da Costa

A simple adjective to define this scientific CALCULATOR...FANTASTIC!

Srabani Sur

Nice....but... The app design is nice. But some displaying error is here if we put -ve symbol with +/- then press X2 the expression is -3^2 after calculate it returns -9. But it should only 9 not -9. If there some another problems, I have not noticed yet.

reeshi paul

When any negative integer is squared and it returns a positive value!! What is dis, calculators cannot b soooo wrong

Edsar Bondoc

Endless ads I will switch to my stock calculator. Your ads are annoying as hell. My God one operation one ad.

Kelvin Tang

Why I need to confirm exit

matt messom

Almost exactly what I'm looking for in a calculator Thanks for your reply. I can now access settings, but when I use the app the screen dims and a rotating red circle appears on the screen. I can still make calculations, but it is rather annoying. It also only seems to happen when I have a wifi or data connection, which makes me a little suspicious!

Gil D

very nice and functionally It had all the functions that I was looking for

Rishav Salodhia

BEST CALCULATE IN THIS WORLD It is a great calc..and have..very great look.

Raghav Dua

Great It is a nice calculator with great UI. Provide an option to see calculation history and it will become the best calculator app.

Lillan Sy

Mediocre Why would you sell backgrounds? Hahaha

Anita Gupta

Unappealing & too many Ads! This app failed to impress me, there are many more fancier and full of features Calculator app on Google Play. Moreover there are too many full screen ads that irritate you. Uninstalled!

Seattle Rex

Wtf Open app ... immediate rating nag. Immediate, before I even used the program! Followed by an interstitial ad. Again, before I even used the freaking program. Eeeeeesh already. A little aggressive, fellas, don't you think? Restrain yourselves for crying out loud. Don't run down and screw one lamb. Walk down and screw them all. Here's your rating based on my honest experience with the app to this point. I hope it's all you hoped it would be.

Gr8 app but constant annoying ads Ads are popping up all the time and then the app closes

Corey Dick

Can't get to Settings on a S6.

Tami Humairah

Useful Thanks a lot. It helps me so much in my math class
