About CALC 1 Financial Calculator
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.

The CALC 1 TVM Focused Calculators have been updated with STO/RLC of all of the TVM values (N, I/YR, PV, PMT, FV, P/YR, C/YR, PER1, PER2 BEG/END) at once! Now you can STO different initial values or quickly switch between different scenarios.
This STO/RCL “object” feature has also been added to the Ratios Focused Calculator.
We enhanced the status annunciators to display all the values not shown on the key previews. So instead of just BEG mode the P/YR, PER1 PER2 are displayed.
Each status annunciator is specific to the Focused Calculator so, for example, BEG, P/YR are only shown on the financial calculators that use them and DEG is only shown on calculators with trigonometry functions.
For version 4.15: The results of the History Item when solving for a Function Calculator parameter has been changed to the value of the parameter.
