TOKYO (MacHouse) – Several days ago, I had to go to the tax office to submit papers. After realizing that I made some mistakes, I needed to use a calculator to add up numbers. So I turned on my iPad Mini. Well, that’s when I found out that iOS doesn’t even come with a simple, virtual calculator. We don’t have one. So we build one. And we’ve just submitted the first iOS application of the year. It’s called CalABC.
Well, CalABC is not exactly a simple virtual calculator. It’s an equation solver. So it will solve the entire equation you enter when you tap the equal pad instead of doing a calculation each time you tap the mathematical sign like +, -, * and /. In this way, you can correct a mistake by using the backspace button when necessary.
- Solve an entire equation only when you tap the equal pad. You can correct a mistake with the backspace button when necessary.
- Tap Copy 1 to copy the answer into the clipboard. Tap Copy 2 to copy the equation into the clipboard.
- Format the answer with commas or not. (See Preferences.)
- Choose one of seven background text images. (See Preferences.)
- With an in-app purchase, get access to additional mathematical signs such as percentage, square root, factorial, 10-base logarithm…
- With an in-app purchase, get access to the Answers table, which lists answers. When you select an answer in the list, CalABC will automatically copy it into the clipboard. You can also let CalABC automatically append the answer of your selection to the equation.
- The application comes with a built-in quick user’s guide (See > Preferences > Help.) on top of a complete user’s guide hosted at our web site.
- File size: 10.2 MB
- No ad!
- iOS 6.0 or higher
- The equal pad will not become active when the equation ends with a mathematical sign (+, -, *, /), the comma or the open parenthesis.
- This application supports the Portrait orientation (vertical) only.
- CalABC utilizes DDMathParser, a math parser package, by Dave DeLong.
