Comments

CALC 1 HP 12C Based HP 10bii Based HP 17ii+ Based TI BA Plus Based
Our design philosophy was to not just copy a hardware calculator, but instead take the best features of each. Then take advantage of the great tools of the iPhone and iPad. Although most developers add features to hardware based calculators, the fact that they are bound to the hardware design make many of the additions awkward. This is a copy of the HP 12C financial calculator with ALG mode.
This does not have the features found on the Platinum and other models with parenthesis and undo.
The calculation mode does not match the hardware 10bii, but we believe this is better since it shows the operators and values. This is a copy of HP's entry level financial calculator with additional features. More features are available, but cost extra with an In-App purchase. This is a copy of HP's high end financial calculator with additional features. Copy of TI BA. Even uses the TI manual for documentation. We couldn't find any extra features.

Basic, scientific and financial calculators evaluate expressions that the user enters. Financial calculators also provide solutions where the calculator executes complicated expressions and the user only is required to provide the inputs.

Financial calculators based on one of these popular hardware calculators (HP 12C, HP 10bii, HP 17bii+, and TI BA) dominate the calculator apps in the iTunes Finance category list of top paid apps.

Although this chart was created by the developers of CALC 1, the reported features are easily verified.

We feel a simple chart of features will help users decide which calculator app is best for them. If you know of any errors in this chart, please contact us.
