Comments on Scientific Calculator for Android

★★★★★ Canned Sardine · Jul 12, 2025

The best RPN calculator app out there. There are less choices available if you want your calculator to have RPN input, so I've tried most of them. This is the one I've always come back to year after year, with no issues. Another great feature is how adaptable this app is to odd screen aspect ratios and sizes. It always manages to look like it was meant for whatever screen I use it on.

★★★★★ Piotr Ryczkowski · Nov 19, 2024

The only calc that allows easy scientific notation i.e. 5.1e3 input. Great overall in other aspects.

★★★★★ Scot Harris · Apr 8, 2025

Finding a free calculator that has 1/x, +/-, and DMS was impossible until now. My only issue is when the result is a negative number, I will select the +/- and a new line starts with a negative instead of turning the result into positive. I have not yet figured out how to start a new line using the result from the previous line as I have only used single line calculators... until now.

★★★★★ Na Ze · Mar 9, 2026

IDK I didn't try it, and I don't, but Sam seems chill and for improvement try to increase the saved calculations if possible

★★☆☆☆ Vince D · Jan 3, 2024

EDIT 2024/1/3: Nice calculator. (1) Pressing 1/x should immediately return the value of 1/current answer or 1/current input, without any further input from the user. (2) The +/- button should always change the sign of whatever value is currently displayed, whether that value is the result of a calculation or user input. Pressing +/- should not trigger the start of a new line and a completely new calculation that starts with zero. These issues have not actually been addressed.

★★☆☆☆ Saeed Faraji · Sep 14, 2023

Although the new updated, is not as good as the old one, still very good. However, there is a bug there that the old one didn't have that bug. 0^0 = 1 The new version show an error message.
