CALC 1 give users clean reproductions of the 12C and 10bII that they will feel comfortable with immediately.

Since CALC 1 contains so many tools, we did not need to add anything to the reproductions. We just share the stack, TVM values and some storage registers so the user can switch between the reproductions and the many CALC 1 tools.

So the AMORT key on our 10bII calculates interest, principle and balance just like the hardware 10bII. If you want an amortization table or graph, CALC 1 has a separate form you use that will already have the TVM values from the 10bII entered (number of periods, PV, payment). Then you can quickly generate either a periodic or annual table or graph that can be shared.

In addition to the 12C and 10bII reproductions, CALC 1 has other calculators that take the best features of these, and other classic calculators, and combines them with the great tools available on the iPhone and iPad.

CALC 1 has separate calculators for TVM, cash flows, business percentages, statistics, math functions that share data with the reproductions.

CALC 1 also has Function Calculators that provide a consistent and efficient solution to a wide range of financial, business, probability and statistical 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.

The 1 List Statistics calculator has keys to create histograms and box plots of data just by tapping a key.
The 2 List Statistics calculator will now plot the x-y data just by tapping the “plot” key.
The curve fitting calculators will plot scatter plots with the the best fit lines by simply pressing the “plot” key.
