Admit it, you’ve done it several times…used your mobile as a calculator. It could be to figure out how much to tip at the restaurant, it could be to figure out which is the best deal on an item at the grocery store, or it could be to perform some simple math that you just don’t feel like doing in your head.
Well, while the normal calculator app you have on your Android device may be sufficient for such simple tasks, you need a heavy weight computing machine to perform more involved equations and to create more than just numerical answers. What I’m hinting at is something along the lines of a scientific calculator.
Scalar Pro is the app that can take your Android and will give you the tools you need to perform interesting mathematical equations, create new ones on the fly using some scripting magic and then view your results in graphical format.
Simply download Scalar Pro, it comes at a very reasonable price, from Google Play and you’ll see what I mean.
From the get go, you will want to head over the Navigation Menu. From here, you can see and get to the various areas of the app. There’s a Settings area where you can customize to your liking. An Onboarding area that helps new users and veterans alike understand how to use the app. What I like best about this area is the map that it shows and the details it provides for each element on the screen. It basically helps users learn, understand and use each tool by breaking down the elements and defining them.
For times when you want to see what went wrong if something is not working as you would hope it would, you head over to the Message Log, which shows every message the app provides based on any errors or changes you may need to make when trying to script or enter calculations.
To make sure the app is functioning correctly, there is a diagnostic check of sorts called the Health Check; not for you, but for the app, to make sure all calcs and functions are correct. While these features focus on app usage, you can also get to the main functions from the Navigation Menu, as well.
First and foremost, you have access to a fully functioning calculator. This means support for basic calcs as well as the ones you would find on a scientific calculator. The keyboard is well laid out and slides sideway to display a full set of keys to cover a variety of functions.
The next step to complex calculating is the ability to write scripts. Here you will be entering formulas and functions using the app’s own scripting language. There are several built in functions to choose from as well. Values are preserved in “constants” that you can access and use in future calculations. There’s no need to “remember”, the app takes care of that for you.
One last area that is very important is the graphing tool. Here, you can bring functions to life through a visual display. Each function can be color coded and the graph itself can be scaled and zoomed in on – lots of great functionality for a mobile app.
I would like to see the ability to save those graphs and maybe even print them through a printing app. That would really be a plus.
For all you mathematicians out there who think you need to lug around your scientific calculator everywhere – think again. You can use Scalar Pro to get pretty much the same functionality in a device you already have on hand.
