Comments on RealCalc Scientific Calculator for Android

★★★★★ notgiven · Jun 22, 2025

This is the PERFECT scientific calculator. I was looking for an easy, compact sci calculator that had an RPN mode. RPN is kind of fun and efficient w keystrokes and the stack acts like another set of memories. It also works in algebraic mode just fine if that is your preference. It has every conceivable function you might need as well as excellent binary and hex functions for machine language programmers. I use the unit conversions constantly. I bought the premium version just to support them.

07/03/26 I'd like to request a feature: A construction calculator for rise-over-run calculations and inches-feet-yards calculations such as 2.4 feet is 2 feet 4 inches and 8/10's of an inch with the closest 1/16'th at 13/16'ths or 3/4's inch. 11/29/20 I bought this several years ago, and it keeps on delivering. A wonderful and useful product. An update: Making RealCalc programmable would be the icing on the cake.

I liked this app but trig functions are wrong e.g. Sin40 is 0.643 not 0.745. Useless!

★☆☆☆☆ Msa777 S · Mar 24, 2025

It started to act weird. No more comments, because I am mad.

★☆☆☆☆ NL1 M · Jul 9, 2026

I've had this app for 15yrs+. Used to be great. Suddenly it has 4+ decimal places and the tab key does NOT open any "dialog" to change it back to 2 decimal places. UNINSTALLED...

They took away fractions from the free version. I've uninstalled it.
