SecureScientific Calculator With History - The Perfect Tool for Every Math Lover!
By Irfan Rosli

Calculator is an Android app with four modes: a scientific calculator, a basic calculator, a graphing calculator and a fraction tool. The developer, Prometheus Interactive LLC, pitches it at students and anyone who needs to check a sum, a function or a fraction without switching between apps.
The modes share one app, so you move between arithmetic, equations and graphs without opening a separate tool for each. Most of the features below fall under the scientific and graphing modes.
The scientific mode covers trigonometric, logarithmic and exponential functions. The listing says it also handles other scientific operations beyond those named.
Every calculation is logged. The history keeps your last 100 expressions and their answers, each with a date, so you can scroll back to see how an earlier result was reached. This is useful when a multi-step problem needs checking or when a homework answer has to be reproduced.
The graphing mode draws graphs in real time and lets you define your own functions. You enter a function and plot it directly, without a separate graphing tool.
The listing presents this mode as suited to visual learners, and to anyone who needs a quick graph away from a desk.
The basic calculator handles addition, subtraction, multiplication and division for everyday sums. It is the mode the listing points to for routine arithmetic.
The listing also names fraction work among the things the app covers, so the fraction tool sits alongside the basic mode rather than replacing it.
The build we hold is Calculator 9.1.5 (APKS split bundle) for Android 6.0 and up.
