  1. Must try ChampCalc scientific calculator, it’s the best scientific calculator on the market.

  2. Check also Scalar, you can write scripts. Scalar is much more than a function calculator. Scalar is a powerful math engine and math scripting language, that combines the simplicity of standard calculators with the flexibility of scripting. Defining arguments and functions, as well as using them in subsequent calculations, expressions and functions graphs, is very easy, use natural math text.

  3. My personal favorite is V Calculator for android. Besides being completely free with no ads, it has a simple clean design. And it has memory functions which I use daily.

  4. It’s good to see Algeo featured here 🙂 Since the publication of the article, we were working hard to update the app and added new features: we have increased the precision of the calculations, added complex numbers, also you can plot polar and parametric plots now. These are only the big features changes, there were tons of small tweaks on the UI. That resulted in a completely new design with a more modern look and more intuitive UX.

    I encourage everyone to check out the new version 🙂
