This past summer we spoke about an iPhone application that took a neat spin on iPhone calculator apps. The app is called Calc Tap and it has recently been updated to include new features.
For those who haven’t used the app, Calc Tap is an elementary calculator that has an interactive paper tape. Before I get into what the interactive tape is, note that this is an elementary calculator, which means it does not include advanced calculations beyond addition, subtraction, multiplication, and division.
In other words, Calc Tap is not a replacement for the stock iPhone calculator. What Calc Tap is however is a very innovative supplement to the stock iPhone calculator.
One of the great features of Calc Tap is that the user interface is very clean and simple. You have the entire calculator along the bottom of the app and a very large white space for calculations. As you begin typing on the calculator, your inputs simply populate in the white space above and Calc Tap automatically adds the proper edits for you within your calculations such as an equals line.
After you have the white space fairly filled up with your calculations, this is where Calc Tap presents its innovative feature, the interactive scroll tape. This is such a useful feature for a calculator, especially if you have very long calculations because Calc Tap allows you to scroll through your calculations in the white space.
In other words, you have a full history of all of your calculations that you can go back and look over in case you made a mistake.
However, the interactive tape does not stop here. As you are scrolling through, you can tap once on any of your operations or results and Calc Tap will copy whatever you tapped to the bottom of your calculations where you can continue to use the calculator.
And of course, if you ever need to erase everything, you can use the clear button on the calculator or simply shake your iPhone to clear the entire screen of calculations.
With the recent update, Calc Tap has received bigger input keys for easier typing, an auto-save feature when closing the app, multipages for those with multiple sets of data, and percentage and VAT calculations.
The 2.0 update also brought new UI changes such as making the background look like a real notepad with a neat page-flip animation using finger swipe and allowing users to modify the font and colors.
Calc Tap is available in the App Store for $2.99.
