CALC 1 is a modern, compatible alternative to the copies of old calculators on the App Store.

- CALC 1 gives you multiple calculators for more solutions.
- Since CALC 1 uses multiple “Focused" calculators, each calculator has more functions for that task.
- You can use algebraic formulas or RPN without having to change modes.
- “Long press" any key to display a hint for that key.
- You can undo any action to quickly recover from mistakes.
- There is online documentation, examples and videos available with just a tap from any calculator.
- The calculators have larger keys and display to reduce mistakes.

Conventional calculators with only one keyboard can only focus on one task, usually the TVM keys. There is not a lot of room left for other financial functions, statistics and math. So there are only a few of those functions and they usually require shift keys.

CALC 1 uses separate “Focused” calculators. You have a more complete, easier to use calculator for each task.

CALC 1 lets you use algebraic formulas but also has an automatic stack for RPN. So there is no need to declare one “mode” as with old calculators. Both are available all of the time.

Algebraic formulas display all of the values, operators and parentheses to make complicated formulas easier to enter and verify. Most calculators only show you the current number being entered and expect you to remember the locations of the operators and parenthesis!

See our documentation for the User Guides for HP 10bII, HP 12C and TI BA users to see how CALC 1 is compatible with the features of these calculators as well as the additional functionality of CALC 1.
