Best free calculators for Android

Best free calculators for Android
Why one should never argue with a 90-degree angle? Because it is always right. *ba dum cshhh* 

Jokes aside, math can be a tough matter to deal with, especially when you don't have a trusty calculator by your side. Luckily, the Google Play Store is loaded with calculator apps – from simple and easy to use to complex, with tons of advanced features – and in this post, we'll show you which are the better ones among them. Better yet, the calculator apps we have picked can all be downloaded and used for free.

One thing they didn't say about calculator++ is that you don't need to press the equals sign for the result to show up

Calculator Cyanogenmod should be here. It has a very simple interface with LOTS of options and you can download themes for it. It's all free and no ads!

Calculator CyanogenMod is the one you want if you need more than the default calculator provides. In addition to the tons of functions within the calculator, it offers calculator widgets. It is not only free but open source (for us old geeks who care about such things). Don't be put off by the name. This calculator is part of the CyanogenMod ROM but it has also been released as a standalone app. It does not require you to root your phone or install a custom ROM.

UseTool is great. It is similar to Flib, but with calculator functionality.

My vote is for my calc. No ads!, its quick and does everything you could want (except graphing). Currency, standard, scientific, tip, percent AND it has the % key on the standard view. Its so weird that so many calculators don't include the % key but they do include the square root or ( ) keys.

I've always used Real Calc. Gotta have RPN and a swappable stack.

How could this article ignore Graph48.. the best RPN calculator that I've seen. It perfectly replicates my HP 48GX. Also, Graph 89 Free - which is a TI 89 emulator. You do need a ROM for it, but you can download them from TI's website as long as you own the physical calc (which I do).

Also take a look at 'Quickey Calculator'. It has many calculators built inside and a scientific calculator too.

The problem with a lot of these calculators is that they display text exponents, square roots and the like, meaning you can't enter real exponents or fractions. My app Awesum Calculator solves this by supporting native input. You should check it out. It also has all the scientific functions you need. play.google.com/store/apps/details?id=com.kaushalm​aganti.awesumcalculator

Very cool. I would need a % key to replace my calculator. Plus android wear support.
