[Windows 8] Bring scientific calculator functions to your computer with Calculator²

Many people use scientific calculators only once or twice a month. This means that the rest of the time, they’re sitting, occupying space, for vast amounts of time. Ditch the physical device and start using your extremely powerful computer as a calculating machine with Calculator² for Windows 8.

One of my favorite things about Calculator² is that it doesn’t overdo anything. By default, it’s in boring four-button calculator mode, with standard memory and history functions being the only special features. When you go to the menu and select Scientific, it all but relaunches, and out appears a large swath of scientific functions, ranging from X² to sech^-1.

There are also a huge set of constants to use. What’s the molar mass of Carbon? Calculator² knows! There are an array of chemical, astronomical, nuclear, electromagnetic, mathematical, and physio-chemical constants for you to choose from, leading one to believe the developer of Calculator² is currently taking courses on physics.

Overall, Calculator² is fairly nice. The ad in the top left alternating between lime green and bright red is quite annoying, however, and the lack of graphing functions is annoying as well. However, for basic scientific and four button calculator needs, Calculator² is the perfect app for your computer.

    Hi Locutus. Thanks for the review! Yes, I’m a physics PhD student and the app is something I’ve worked on in my spare time. I haven’t ever seen a calculator with a good, easy-to-access constants list, so that was one of my motivations for building the app.

    The Windows 8 version is actually a port of the Windows Phone app: http://windowsphone.com/s?appid=b7b925e4-1c74-4c2b-8751-0cc6cf8eee6e. I plan to add the Programmer, Currency Converter and Unit Converter before general release, and from there work on more features to add, one of which will be a graphical calculator (also an RPN calculator, which I get a lot of requests for).

    With regards to the ads, there is an in-app purchase option available in the app bar to remove them, which costs £0.99. I do agree that the ads are annoying (they will vary a lot more as the ad networks start taking off), but they allow me to keep the app free for people who will only ever require light use. I find this issue really interesting now that I have the perspective of a developer. I’ve spent a lot of time and effort building the app, which also costs me to maintain. The ads and in-app purchase help cover the costs and bring me a small amount of income. At the moment this really isn’t a lot, but I’m hoping that might change with the release of Windows 8/WP8! On one end of the scale I receive the odd one star review complaining about the ads, but for each of these there are others who say that they paid for the app to support the developer. The support really does help because I would love to be able to build more apps and do this full-time. It will also be interesting to see how this works out with Windows 8; I think people are accustomed to seeing ads/paying for apps on smartphones/tablets, but not on their desktop PC.

    Anyway, thanks again for the review, I’m glad you like the app! It is at a very early stage, so expect more features and a lot more polish in the coming weeks!

    Regards, Richard Walters.
