The Number Line

The iOS Number Line App was created in response to requests by visitors to our popular https://numbermaniacs.com website. Our visitors wanted a standalone application that does not require an Internet connection to locate numbers on a number line.
In addition to showing numbers on a number line, this app also includes a calculator that can calculate the absolute difference between two numbers. This may be especially helpful when dealing with the absolute difference between a positive and a negative number.
The Number Line App does not require an Internet connection, so you can use it anytime and anywhere. The goal was to make the app intuitive, clutter free, fast to operate, and easy to use. We hope the Number Line App will become one of your favorite math apps.
