RealCalc Scientific Calculator

A Google user

Best calculator I've used and I've tried a few. I was lucky to find this one early and have never wanted it to have a function it doesn't have. I'm a little surprised that I haven't needed a graphing function in that time (several years) but I also have had my trusty, old TI-83 Plus handy and would always rather use that than a phone app (for graphing). Anyway. Never had a problem with this app. Will buy the paid version when I've built up enough Play Store credit.

A good scientific calculator. PROS: Much like a real Sharp/Casio, easy to use. All the basic features work, passing the crucial calculator tests (such as 1/9=ans/9....*9*9=1). Can paste copied numbers for use. Simple constant/conversion sub-menus, easy to find, use. CONS: ONLY 10 digits-can't enter the $29 trillion US debt to the dollar - developer said it won't be added. No multiline history display, 1-line. No fractions and hours. 3^97 mod 353 = fails (40). IMO, Champ, CalcTastic, then Real.

Hands down the best calculator app I've used. Because its intuitive, there are few hidden features and everything you need is right up front. Its memory feature is also nicer to use than some others. I've since switched to Apple, and while there are countless dozens of great calculator apps on their store, most are too cumbersome for my taste or else they simply lack all the features of RealCalc on Android. This app is so good, I keep an ancient Motorola Turbo from the late bronze age loaded with this App and Spotify sitting by my work area.

I used to use the free version of this app specifically because it had a homepage widget included, but one day the app updated and the widget just disappeared entirely. Apparently they took that feature and moved it to the paid version. I understand the need to earn a living off of software you develop, but it doesn't feel good to be given something and then have it taken away and be asked to pay for it suddenly.

So long as you aren't expecting it as something that it isn't, then this is a great app/calculator. And what I mean by that is that this is - strictly - a scientific calculator - so no multi-line displays or super fancy functionality or anything like that - but that it fulfills its function extraordinarily. This thing is basically a well and cleanly executed scientific calculator on a phone - equivalent to the act of going out to a store and getting a good scientific calculator. You should get this app simply so that you can have a simple and powerful calculator on you at all times in case you're ever without an actual calculator but need one.

REALCALC PLUS REQUIRES INTERNET! This wasn't made clear when I purchased the product! It attempts to obtain a license via the Play Store. (This is the only app I've purchased that does this!) If it can't get a license - because, perhaps, the user is offline, or the Play Store's disabled/ blocked - then the features in the Plus version are disabled! This is crazy, as I don't normally have a data connection. In short, this app's Plus features CAN'T BE USED RELIABLY

I've decided to buy RealCalc Plus after years of using the free version. It works great, no bugs, no ads were ever seen on the free version. I think it was about time I supported the developer.

Excellent calculator and I use it in rpn. Has all the features I need. I liked it so much I upgraded to the paid version. Enhancements well worth the cost. I did have a question and emailed the developer and he responded right away, a pleasant experience and my question was answered. Outstanding calculator, very stable, very pleased, highly recommended. btw this has been tested on Samsung Note 8 and Note 10. Rich M. Burnet, Texas
