Free-to-use scientific calculator app
The
Scientific Calculator
(SciCal) app is a free
utility
from FirOZ LLC, allowing you to make calculations on the go. Beyond the standard
calculator
app, it allows you to access more advanced features such as
natural display
or
trigonometric functions.
In terms of interface, it looks like a standard Sci Cal, with
minimalistic buttons
sprawled across your touchscreen.

Designed for experienced Scientific Calculator users, this app
doesn’t come with its own tutorial
. Some users might find difficulties understanding what each button does, not to mention additional commands such as
SHIFT or Scientific Constants
. You can also check out

Great for STEM on the go
The Scientific Calculator app offers more operations than standard calculators. Apart from
basic arithmetic
such as addition and subtraction, you also gain access to
exponential and logarithmic functions
. You can even use trigonometric functions like Sine, Cosine, and Tangent, and their hyperbolic counterparts. As mentioned, the app tries to emulate an actual scientific calculator, owing to its minimalistic and
color-coded
designs.
One feature of the app is that it retains its
natural display
. This means that fractions are displayed as the numerator on top of the denominator, instead of automatically converting them to decimals. Aside from the visual convenience of seeing exponents in superscript, it also
retains the stored value
of an input or result of a previous operation. It is important for students of Science, Technology, Engineering, and Mathematics (STEM).
Unlike real-world scientific calculators that come with manuals, this one does not. It is convenient and straightforward, letting you
copy equations
by simply tapping its screen. However, it doesn't help new users to learn how it works. For example, the SHIFT button is used to access those orange-colored functions on top of every button. Similarly, there’s no list of what the numerical constants under
CNST
are.
A good starting SciCal for students
If you’re one of those people who needs a SciCal close by, this Scientific Calculator app is a good place to start. It comes with most of the
commonly used features
and even throws in alternate functions and its own set of scientific constants. You can even
use its display screen
to instantly copy the display to your clipboard. The only challenge here is it lacks tutorials.
