Calculators That I Use Nowadays

I have shared several decent calculators and graphing tools in this blog, but in this post, I’m going to share the calculators that I actually use nowadays. The calculators I use depend on the task that I’m doing. I use my phone for short and simple calculations, but if I’m studying or working for an hour or more, I use an actual calculator to avoid distractions. Here are the four calculators that I use most of the time.

1.) Calculator (Mac)

When I’m using my laptop, I use the default calculator app of MacOS. This app allows the user to choose among basic, scientific, and programmable modes. It also supports base 8, base 10, and base 16 number systems. Personally, I only use the basic and scientific calculators and I have not tried the programmable calculator yet. 

2.) Google’s Calculator App (Android)

Google’s calculator is a simple and beautifully designed app for basic calculations and scientific calculations. It can store previous calculations. I like the simplicity of this app, so I use it most of the time for basic calculations when I’m using my Android phone. This app is compatible with WearOS.

3.) Advanced Calculator FX991 (Android). This is a paid app but I really like it because it mimics the interface of an actual calculator (see image below). I’ve been using it for six months and so far, I really liked it.

4.) Casio FX991 ES Plus. Aside from apps, I also keep a Casio 991ES Plus. It’s not that I wanted to buy this calculator,  but it was the only decent calculator in a store the time when I wanted to buy one. So far, so good, I’ve gotten used to it. I think I will be using it for a long time.

That’s all. Maybe you can share the calculators that you’re using in the comment section below.

Turn Your Device into a Portable Scanner with Tiny Scanner

More than a  year ago, I shared to you Genius Scan, a portable scanner app. There is also a similar app called Tiny Scanner which is both available as iOS and Android Apps.

Tiny Scanner is an app that turns your iOS or Android device into a portable scanner by letting you take a photo of a document and saving it as PDF or as images.

The app has the following notable features:

  • detects page edges automatically
  •  pages can be set in different sizes (Letter, A4, Legal, and more).
  • images can be scanned in color, grayscale, or black and white
  • it has 5-levels of contrast for monochrome texts.
  • documents can be protected by a pass code.
  • available for both iPhone and iPad

Documents produced by Tiny Scanner can be shared through Email, Dropbox, Evernote, Google Drive or Box.

Tiny Scanner can be used by teachers to scan some printed documents such as test papers, handouts, images or pictures. This will also be useful in scanning books to be shown in a large screen or projector.

Take Notes and Scribble with Inkflow Visual Notebook

I usually solve problems and organize my thoughts by taking notes  while on the go, so I have been looking for a free note taking, scribbling, or doodling phone application for some time. I have downloaded and tested several applications, but I was not really satisfied by any of them.

A week ago, I purchased Inkflow Visual Notebook for iOS and I’m very happy with it, although I personally think that $7.99 is quite expensive. What attracted me the most is its ink which really feels like a smooth fountain pen.

Inkflow is simple but user-friendly. For example, its selection tool, is very handy to use: select the part that you want to edit and two icons appear which allow you to easily enlarge, reduce, or rotate the selection. Also, Inkflow uses vector graphics, so the ink stays sharp even if it is zoomed in. Further, I have not experienced any lag although I have not really created a lot of notes yet.  » Read more
