Calculadora‪‰‬ +4

Being over 50, I wanted a calculator whose buttons and display would be large and easy to read without reading glasses. This app fits the bill. My only complaint is, the division and multiplication symbols are on the left, which is different from most other calculators, which slows me down and/or causes keying errors, since I often have to make multiple calculations quickly.

It would be nice if both calculator apps and "real" calculators had standardized key positioning like alpha keyboards do!

This app is my go-to calculator app. I love the large buttons and accuracy! I typically don’t write negative reviews, but I am very frustrated that the developer would tamper with a good thing by moving to full page ads. Just when I need a quick result, I am greeted by a full page ad, making me figure out where the darn close button is or worse yet opening up the ad. Half of the time, I can’t remember what I was going to calculate in the first place, after the intrusion of a stupid full page ad! This app is easily a 5-star app when it comes to visual layout and functionality. But, it fails when you factor in the ads component. The developer is obviously more intent on making more ad revenue than pleasing their customer base. So, I have reduced my rating to 2 stars. The more I see the full page ads, the more I think about searching for another calculator! Developer - take note! Your decision to move to full page ads to generate more revenue might actually cost you customers which would generate $0 of revenue!

I absolutely loved the simplicity and ease of use for this calculator app. And then, relatively recently, they started interrupting your ability to use it without first looking at super annoying full screen ads. Now it takes longer to use for even the most simple calculations, and is frankly just super annoying. I loved this app for many years, but now I think it’s time to move on. I’d definitely pay a small one-time fee (couple/few bucks) to avoid the ads but until that becomes an option, I’m probably going to seek out a different one that’s either free or let’s me pay to go ad-free. They ruined a good thing.
