RealCalc Scientific Calculator

Nice, easy to use RPN Scientific Calculator. If you need a calculator more advanced than what came with your phone, use this one. Reliable, accurate and easy to use. Some functions limited only to the upgraded model, yet what is available should suffice for most of your needs.

This is a fantastic calculator app, I've used it for years and it never fails, I now have the same relationship with this as I did with my old physical calculator. Bought the premium version several years ago, not for the extra features (the free version is fine) but to show my appreciation.

A great scientific calculator. Ads are a bit annoying, price for upgrade on this page would be helpful. Been using for years, no problems to date. Look no further, unless maybe your a rocket scientist.

The best calc app ever. I recently transitioned from a 16:9 aspect ratio phone to a 21:9 and i realized that the UI dose not scale on other aspect ratios. Please make the ui to adjust to the aspect ratio of the screen or an option to swich betwen 16:9 and 21:9 as those are the most probably aspect ratios. Kudos ro the team. 👍👍 Great job.

The paid version (RealCalc Plus) is my most commonly used calculator. It has just the right functions and configurations to be set up ideally (RPN for me) with everything I need and nothing I don't. With excellent accuracy and aesthetics, I couldn't be happier.

Brilliant app. Superior to many physical purpose built scientific calculators. And the bonus being that it exists as an app on your smartphone, instead of a separate physical calculator. 'Dan Razzel' please take time to evaluate apps correctly before leaving negative 'incorrect' comments. It might possibly be wise to spend more than a few minutes evaluating an app that has most likely taken the developer many months to create. The decimal value of 123 is equal to the hexadecimal value if 7b.

Absolutely the best calculator app if you are looking for the look and feel of a real calculator. This thing operates EXACTLY like a and-held calculator. I have had this app for a few years and was more than happy to pay for the premium version. Highly recommend!

Love the app. I've been using the free version for years. I finally decided it was time to show some gratitude and, just now, purchased RealCalc Plus. I thank Quartic Software for such a robust FREE app. I look forward to the additional features of the Plus version.
