Comments on RealCalc Plus for Android

★★★★★ notgiven · Jun 24, 2025
GREAT calculator. It has every function I need and RPN entry if that is your fetish. Just finished testing out the fraction math with standard font-excellent. I use the unit conversions constantly when scientific articles use metric measurements for things I have no feel for, like Newtons rather than lbf. Got premium to support the developer.
★★★★★ TJ Leverette · Sep 26, 2025
This is the best RPN calculator available for Android, and I've tried all the good ones. An excellent app that I use multiple times a day. Three thumbs up 👍👍👍.
★★★★★ Todd Wilson · Apr 23, 2026
I've been using the free version for 15 years. I figured it was time to pay the developer for it, so I just paid the $4. Sorry it took so long. It's fantastic. Thanks!

Wrong answers! The Sin of 45° is .7071 and not .8509, which is what this app gives you. The app gives other incorrect answers when attempting to use trig functions.
