Mihir

It's named as a simple calculator but it has all the modifications you need and even its name is changeable.

★★★★

Timothy Schuebel

Simple + Almost Perfect, if only there was a way to get rid of the banner ad on the bottom, then it would be perfect. I get it tho , devs gotta eat too))

★★★

Pooh Sanders

In functionality, a really nice calculator. Small (~45MB), yet lots of options for calculation & conversion. However, the interface is e.x.t.r.e.m.e.l.y slow. The buttons react only seconds (yes, plural) after being pressed. This leaves -y̵o̵u̵- me oftentimes wondering "did it even register the button-press??" and can become quite annoying. Therefor, overall, I uninstalled and do not recommend this app

★★

Used to be ok, just a banner ad at the bottom. But now when you switch screens you get a full page ad, not every time but often enough to be really annoying. You can't get rid of it, you have to either wait it out or swipe up and shut the app down, then reopen it. To get rid of ads you have to pay, not just a one off payment but every month. No way I'm doing that! I've now uninstalled it and downloaded Samsung calculator. Free with no ads whatsoever, & just as good as this one.

Riddled with ads, claims in-app purchases whilst happy to pay there is no option anywhere nor can you change anything .. . .. BEWARE of the 'vendor preferences ' in the consent screen as per usual there are hundreds that are on by default and takes a good 5 minutes to turn each one off
