CALC 1 allows you to customize your calculator so you can perform calculations quickly and accurately.
CALC 1 is a true "programmable calculator" in that the individual calculator KEYS can have programs assigned to them.
While programming an old hardware calculator could be a challenge, CALC 1 takes advantage of the modern feature of your iPhone or iPad that allows you create powerful customized calculators quickly and easily.

You can simply copy and paste keys from the many calculators that come with CALC 1 to create a customized calculator. You can create as many custom calculators as you want!

CALC 1 can automatically create keys for you from an expression you entered. So anytime you enter an expression, just have CALC 1 create a key so you never have to enter that expression again.

You can also write powerful custom JavaScript programs that can be executed from a calculator key.

CALC 1 also has “Function Calculators” that are created from standard JavaScript functions. Just copy the JavaScript function into the clipboard and CALC 1 will automatically create a calculator that will calculate the function.

The CALC 1 Function Calculators provide a consistent and efficient solution to a wide range of problems. You can also easily create a graph of the function by entering the range and selecting the independent variable. Solving for a parameter allows you to perform breakeven analysis for any parameter of any function.

* Simple, 1 key stroke plots of functions and data for easy data visualization. (X Y, scatter plots, box plots, and more)

* CALC 1 uses JavaScriptCore, the same JavaScript engine that is in WebKit used by Safari.

* Over 100 functions provided with CALC 1 within JavaScript.

* A List Manager and Data Manager to provide quick and accurate importing of data.

* Use algebraic, chain or RPN calculation modes with an automatic stack.

* The CALC 1 documentation site has over 100 pages of searchable documentation and videos. All calculators and utilities have a help link (?) that opens the documentation for that calculator.
