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.
★★★★★ Tony Hedgewolf · Feb 20, 2025
I've been using the free version for several years now, and it's absolutely perfect for me. The only thing I wish for is to have grains added to the mass conversion list.
★★☆☆☆ Борислав Николов · Nov 17, 2024
Where are DEC, HEX, OCT and BIN buttons gone? I've got them on another phone highlighted in yellow, the version is the same. Your screenshots show the presence of these buttons, too. What is your explanation, please? Thank you.
★☆☆☆☆ Mark McKinnon · Dec 11, 2025
They took away fractions from the free version. I've uninstalled it.
★☆☆☆☆ Msa777 S · Mar 24, 2025
It started to act weird. No more comments, because I am mad.
★☆☆☆☆ David Morris · Mar 29, 2026
I liked this app but trig functions are wrong e.g. Sin40 is 0.643 not 0.745. Useless!
