Version 4.50 Minor updates for the latest iOS. Version 4.40 This is a major free update with a new plotting frameworks with over 30 new plots for easy plotting of expressions and data to communicate information clearly and efficiently. A new Expression calculator includes keys for “1 tap” plotting of the current expression, 1 to 5 stored expressions, expression with shading, and parameter plotting. The plotting is combined with keys to solve, integrate, calculate max, min, calculate where 2 expressions are equal and dydx to help you analyze expressions. Copy, paste, plot! Copy data to the clipboard, paste it into the List Manager. Then with 1 tap create histograms, box plots, normal probability plots, scatter diagrams and more. The updated 1 List Statistics calculator will plot histograms or 1-5 box plots from list data. It also has new keys for 1 tap calculation of summary stats, percentile, inverse percentile and sorting. New Normal and Student’s t Distribution calculators feature z/t tests and intervals from calculated or entered data. Tests can be plotted as well as lower tail, upper tail, two tail or central PDF plots. There is a key to plot a normal probability plot of the data and another to create lists of random normally distributed values from the entered mean, standard deviation and n values. The updated 2 List Statistics calculator will plot list data. The curve fitting calculators will plot scatter plots with the the best fit lines by simply pressing the “plot” key. The plots use Apple System Colors that automatically adapt to both light and dark modes, vibrancy and changes in accessibility settings like increased contrast. To help the entry and managing of data, lists of data can be stored and recalled with the standard STO/RCL keys. Each calculator that uses lists of data now has 5 keys to STO and RCL the lists that are unique to that calculator. In addition, there are 8 lists that are shared between calculators. Lists and other data can be viewed and edited in the new Data Manager. Now CALC 1 can open text files containing data for analysis. From the Apple Files app, files can be opened by CALC 1. Then the file can be viewed and edited in the Data Manager and then parsed and copied to the CALC 1 statistics lists for quick and accurate entry of data! Data can be manually entered, pasted from the clipboard using the List Manager, imported from a text/csv file (or AirDrop) into the Data Manager or dictated into the Data Manager. Getting data entered quickly and accurately is important and CALC 1 has the tools for the job!

Updates to the plotting! Plots now use System Colors that adjust to dark mode and automatically adapt to changes in accessibility settings like Increase Contrast. All of the parameter values are now shown on the plots from the Function Calculators. A new toolbar button will quickly display the latest history detail. A new expression editor allows full keyboard editing of expressions. Expressions can be restored from history.

A button to automatically create a Function Calculator from an algebraic expression has been added. This is an easy way turn an expression into a Function Calculator so the function can be plotted and you can solve for “x” as well calculate “f(x)” for different values of ‘x’. This button is next to the ‘Create Key” button in the History Detail for algebraic expressions. Now users have more ways to customize CALC 1 help them save time and reduce mistakes with the problems they face the most. A Search Bar has been added to the Function Calculator list now that there are over 60 of them with more being added.
