Tables Released

Version 2.4 is now available on Google Play.  This adds a new table screen to view graph equations in table format.  You can also now fling the graph (except for log scaling).  The update includes a few other minor changes and fixes.

Table for Equations

The next update will add the ability to view a table of points for the graph equations.

MathAlly 1 Year Old!

MathAlly Graphing Calculator has now been on Google Play for 1 year.  Many features have been added through updates since its initial release one year ago!  Here are some of the highlights:

• Custom Keyboards (Plus version only)
• Trig identities
• Differentiation
• Definite integration
• Matrices
• Inequalities (for graphing and solving)
• Graphs not in form y=... such as conic sections
• Polar and Cartesian graphing (Plus version only)
• Copy/Paste
• English descriptions to step-by-step screen (Plus version only)
• Workspaces (Plus version only)

Of course, there have been many other additions and fixes over the past year and there are still more to come!  I have just uploaded another update to Google Play that fixes a few problems and makes some enhancements.

Thanks to everyone who has downloaded and used the calculator over the past year, especially those who have purchased the paid version!  Also thank you to all of those who have provided me with valuable feedback.  Some of the ideas for feature additions have come directly from users.

Workspaces Update on Google Play

Version 2.3 is now on Google Play.  This adds workspaces to the paid version.  It also includes some other improvements and bug fixes.

Workspaces

The next update will add workspaces to the paid version.  A workspace is a place where calculations are saved to.  Currently the calculator only has one workspace (results history in the calculator), and only the last 20 problems are saved.  With the next update, you will be able to create new workspaces and change their size so they can store more results.  The first screenshot shows the screen to manage your workspaces.  The second one was shown after pressing the "View" button from the first screen.

As you can see, you will be able to export and import workspaces like you can with custom keyboards (first screenshot).  When viewing workspaces (second screenshot) you can select problems by clicking on the input.  Once an input is selected, you can copy it to another workspace, delete it, or adjust its position in this workspace.  To adjust its position in this workspace, simply select "Adjust Position" from the menu and then click where you want to move the selected items to.

If you click on a result while viewing the workspace, the step-by-step screen will be shown for that problem.  You can also long-click on any input/result to highlight it for coping it (or part of it) to the clipboard.  Finally, if you click on "Settings" you can change the maximum size of the workspace.  After the max size is reached, the calculator will delete the oldest item when a new expression is executed.

Version 2.2 Released

Version 2.2 is now up on Google Play.  This adds a new Number Format setting (under General).  This allows the user to choose the decimal mark, digit grouping, and function argument separator that they wish to use.  Previously the decimal mark was always a point and there was no digit grouping.  When digit grouping is turned on, digits are automatically grouped as you enter them (unless you have basic text entry enabled).  For example, if you set the digit grouping to a comma and enter "12345", it will automatically be grouped and display "12,345" in the entry.

Currently the calculator history only stores the last 20 calculations in the calculator history.  I have had requests for a way to permanently store calculations.  For the next update I am planning on adding a way to permanently store calculations.  I have some ideas on how I would like to add this feature and I think it will end up being pretty neat once I get it in.  This feature will only be available in the paid version.  Once I get some of it implemented I will post some screenshots with more information on how it will work.

Matrix update published.

Version 2.1 has been published on Google Play.  This add the new matrix operations ref, rref, lu, qr, cof, eigval, and eigvec to the paid version.
