What sets CALC 1 apart is its ability to provide more solutions than all the other top-selling calculators combined while maintaining a simple and intuitive interface through the use of Focused Calculators and Function Calculators. This innovative design ensures that you have a dedicated, clutter-free interface for each specific problem you're working on, rather than having all the functions mixed together into one complex calculator.

With innovative Focused Calculators and Function Calculators, CALC 1 goes beyond the limitations of hardware calculators and their app counterparts, empowering you to calculate, visualize, and understand complex concepts effortlessly.

CALC 1 offers a wide range of Focused Calculators, including Time Value of Money (TVM), Cash Flows, Statistics, Probability Distributions, and more. These dedicated calculators eliminate the clutter of multiple shift and inverse function keys, providing a comprehensive solution set for better understanding and decision-making.

CALC 1's Function Calculators, powered by JavaScript, offer over 70 additional tools for consistent and efficient problem-solving across various financial, business, probability, and statistical domains. Users can easily create graphs and perform breakeven analysis for any parameter of any function, enhancing their ability to visualize and understand the underlying concepts.

Designed specifically for iPhone and iPad, CALC 1 leverages the devices' hardware to enhance usability and reduce errors. Features like key previews, which allow users to see inputs at a glance, and key hints, which display details of a key's function without disrupting the user's train of thought, contribute to the app's visualization capabilities. The history details feature enables users to review past calculations, while plots are essential for visually understanding data. The List Manager allows for quick review and editing of manually entered data, further enhancing the app's user-friendly experience.

In addition to the Focused and Function Calculators, CALC 1 includes clean reproductions of the HP 12C and 10bII that share data with the other calculators, ensuring users feel comfortable and familiar with the interface from the start.

With contextual help documentation and over 20 video tutorials, CALC 1 ensures users can quickly master the app's extensive capabilities, deepening their understanding of financial concepts and problem-solving techniques.

While CALC 1 is designed for finance, accounting, and business professionals and students, its user-friendly interface and powerful calculators make it an invaluable tool for anyone looking to better understand and manage their financial decisions.

Perfect for teaching my finance students

I teach an upper lever finance class at a local university. The Finance department requires that the students use TI BAs, so I use that primarily for in class examples.
When I prepared for class and write my exams, I always work the examples on CALC 1 to verify my answers. I love how I can export the history details to Notes.
And I also have the inputs for the TVM calculations recorded (N, I/YR, PV, PMT, FV, PYR, CYR and BEG/END) so I can double check all my inputs and answers. Just having the values shown right on the keys prevented a lot of miscalculations. I like that this app also has a 12C that I am very familiar with having taken the CFA. I’d give it an A!

I usually use an HP 12CP but this has replaced that long standing relationship. Seeing the value on the keys is worth the price of admission. I am amazed by the scope of this app. HP should hire the developer to design their next product.

I love this app. It works just like my old HP calculator.
