Description
This free scientific calculator offers a number of useful features allowing you to carry out advanced calculations. Its simple and intuitive design makes it a pleasure to use. The calculator has all the functions that would be expected of a scientific calculator and a number of more advanced features too, including complex numbers and matrices.

The super fast algorithms allow the scrolling and zooming of 2D and 3D graphs in real time, using the touch sensitive screen.
Graph implicit equations in 2 and 3 dimensions. e.g. x²+y²+z²=5².
Graph inequalities in 2 dimensions. e.g. 2x+5yGraph functions of a complex variable.
Display up to 5 graphs on the same screen.
Active analysis of functions, for better graphing of 2D functions with singularity points. e.g. y=tan(x) or y=1/x.
Intersections on 2D graphs.

The calculator is customizable allowing you to change the colors of the screen, background and all the individual buttons, allowing you to personalize its appearance.

Comments on Scientific Calculator for Android

★★★★★ Shafayat · Feb 25, 2022
Love this app. Long time user. Noticed a tiny issue, if you set ANS to 0 and do ANS/ANS, you get 1. Also, would make a big difference if the minimum haptic feedback was shorter, say 5ms. Currently even setting it to 1 seems delayed and long.
★★★★★ Aurelius Freeman · Sep 14, 2023
'Scientific Calculator' is an absolute game-changer for anyone who loves math and solving complex problems. It's so easy to navigate through the various functions and operations. Whether you're dealing with basic arithmetic or diving into advanced trigonometry, this app has you covered.
★★★★★ Dsgnr Look · Nov 2, 2024
This is the best calculator app on the play store hands down! Also, could you please make the sliders snap in increments of ±5% in the next update? People with ADHD probably can't handle the free sliders
★★★★☆ Charlie Croucher · Dec 2, 2023
Great calculator has all the bits you need, but haptic feedback would be a great addition
★★★★★ jrs otr3 · Jun 16, 2025
I've used other calc's, Philip Stephens calc's are now the only calc's I've used for a long time. I'm seeking tutorials for how to use all the functions and features of calculators.
★★★★☆ Andrew Bohlken · Nov 16, 2023
Very good calculator as far as I can tell (I'm no expert). More instruction on how to use various functions would be invaluable, as would a help/search function. Eg can I edit the axis and add points on a line in a graph - where do I find out? Can I change axis between log and linear or semi log etc.?
★★☆☆☆ Toma Hawk · Dec 14, 2023
Thanks for reply. After a calculation, the outcome stores in ANS. I will then retrieve ANS and add a minus before it, that is -ANS ; then I use the figure that is made negative for countercheck my calculations in order to ensure that I did not make any entry errors. I also use the same figure stored in another memory. And the final sum should be zero meaning that there is no human operator errors incurred in the calculation process. Hence, the +/- button is very important to me. To place a - sign
