Number Base Master

This is an app that deals with numbers in different bases. Unlike others that only work with base 2, 8, and/or 16, this app works with any number base from 2 to 24.
There are two function screens:
On the first screen you can convert a number from one base to another. Simply type in your number and then drag to choose the input base (the base of your number) and the output base (the base for the number you want).
On the second screen you can perform the 4 basic operations (+, -, ×, ÷) on numbers of different bases. For example, you have the expression 5+7 in base 10, and you want to know what the answer is in base 8: type in "5" as the "first number", choose "+" as the operation, type in "7" as the "second number", slide to set the "input base" to 10, and slide to set the output base to 8.
App is completely free to use and does not collect any data.
