Reviews From google play store

Automatic function graphing is amazing! So is the smooth transition into history, nice touch. I wish you could use greek letters in the function panel. Also, a black mode would be even better than dark mode, like the one in your compass.

After trying about 12 this is the better one, there are some with flashier graphics, but I found if I put this in:- 4 x 100 + 2 x 4 = I'd expected to see 408 which this App gives :) But some of the others actualy show:- 1608 ??? how rubish is that.

Now has a delay and a full paged add upon opening. Utter rubbish. They ruined a perfectly good app, a calculator app needs to be up and running straight away!

it is flawed . you think its giving incorrect answer until you realise it is aligned wrong and the most significant numbers are off the left of the screen!

Full-screen ads with a Calculator app? You have to be joking!

Good app with multiple options....highly recommended

cancer.. uses clickbaity ads tactic without ability to close the ad

Great calculator I use it all the time!!

Contains ads? Why? It's a freaking calculator

Too many ads..very bad
