Ratings and reviews

I found RealCalc back in 2013 and it immediately became a home screen staple. A few years later, I became a paying customer for RealCalc Plus, not because I needed more features, but because I felt that I should reward the developer for the use I was getting from the app. Now, in 2021, I still have it on my home screen and still use it as much now as I did then.

It's the only calculator that I have been using on my mobile, and outside. Nice product.

The only thing bigging me with this calc is there's no option to expant the "screen" to show calc equasion along with the result... Because sometimes you need to peak on it (to check for typos or on long add stretches to check if you added the 17th value or not). And yes, you have space - you allow user to resize the calc itself, so there's space to shrink proportionally everything to fit half size "formula history" line.
