- Bug fixes - Updated for iOS 26

Great news! We expanded the availability of our latest features. Now, users with iPhones running iOS 15.0 and above can experience everything we introduced in the recent update. This means even more people can enjoy the app's full potential.

- We redesigned the statistics and regression views for a more modern look and ease of navigation. - Added screenshots in the App Store for smaller iPhone sizes.

We redesigned the statistics and regression views for a more modern look and ease of navigation. We hope you like the new design. Please let us know what you think.

We changed the default color of the buttons. If you don't like them, don't worry, because we also added a feature that you can set the color of the buttons based on your preference. This update also extends the support for the dark mode for the main screen.

Bug fixes

Long press on the screen for copy/paste capability.

Performance improvements.

We added the capability to draw a Moving Average Plot. It's useful to find longer term trends in time series data such as stock prices or number of items sold over time. You can change the period and offset in the plot.

We expanded the line graph capability to be able to choose between three graph types: line, area and bar. Simply choose "Plot" under the statistics for X, or Y or (X, Y) to plot the values of X, or Y versus the index, or X versus Y.

This update resolves an issue for users who have their iPhone set to a region where comma is used as decimal point. This update fixes the issue for Probability Distributions, Confidence Interval and Hypothesis Test sections.

We added the capability to plot line graphs. You can plot a line graph of X, or Y values versus index or Y values versus X values.

We improved the import csv files feature. Now you can assign the imported columns from a .csv file to any of the lists (x, y, frequency, or other custom named lists).

We improved the copy-paste from the Universal Clipboard feature. Now you can copy the values of a list (from one row or column or multiple rows and columns) from your homework file, Excel or Numbers spreadsheets, or even tables in Notes app or any other file from your mac or iPhone and paste it into this calculator to do statistical analysis. Since this feature takes advantage of the Universal Clipboard it works across your devices. Copy from your Mac or iPad and paste right into this app.

Now you can copy the values of a list from your homework file, Excel or Numbers spreadsheets, or any other file from your mac or iPhone and paste it into this calculator to do statistical analysis. This feature takes advantage of the Universal Clipboard and therefore works between your devices.

- Histogram Plot Improvement: Now you can trace the histogram plot by touching the bars and moving your finger on the plot. - Confidence Intervals and Hypothesis Test Improvement: Now you can preview the list before selecting it to use in Confidence Interval or Hypothesis Test calculations.

We improved the Scatter Plot. Now you can trace the scatter plot points by touching the points and moving your finger on the plot. Furthermore, you can share the scatter plot.

- We added Confidence Interval calculation and step by step explanation for "Population Mean" with known population standard deviation (Z-Interval).

Added Scatter Plot. If you have entered X and Y values and they have the same number of elements, you can go to Statistics and see the option to view a Scatter Plot of (X,Y) Values.

- Added hypothesis test for population mean difference with known population standard deviations (with step by step explanation and graph)

- Added hypothesis test for population mean with known population standard deviation (with step by step explanation and graph)

- Added hypothesis test for population mean difference with step by step explanation and graph

- Added hypothesis test for population mean with step by step explanation and graph - Added capability to share or save screenshots of Histogram, Box and Whisker Plots, or Probability Distributions

- Now you have hypothesis tests for one population proportion and difference in two population proportions. That includes step by step explanation and graph.

- Now you can perform hypothesis test for one population proportion. That includes step by step explanation and graph.
