Geometry Pad 2.7.0

Geometry Pad 2.7.0 is now available on Apple App Store and Google Play. Here is what’s new.

The protractor tool lets you measure angles. You can also draw lines at an angle. When tool is active you should see two lines displayed: base line and angle line. You can move the base line’s end and middle points to align it with a line or other objects. You can then move the end point of the angle line to measure an angle.
Protractor’s angle line has three different modes of operation controlled by the button displayed in its middle point. The default mode is rotation used to measure angles. If you tap the button you can also activate drawing or resizing mode. When in drawing mode, you can draw lines at the current angle by dragging the end of the line. Resizing mode lets you change the length of the line angle without changing its angle.

Parallel and Perpendicular Lines
Parallel and perpendicular snapping was replaced by three dedicated tools: Parallel Line, Perpendicular from a Point and Perpendicular to a Point.

SVG export
You can now export the entire document to SVG format.

Geometry Pad 2.6.0

We’re happy to announce that Geometry Pad 2.6.0 is now available for Mac, iPad and Android devices. Here is what’s new:

A dedicated tool for building polylines. Especially useful for measuring distances on maps. The total length of a polyline is calculated in the Metrics tab of its properties window. Or it could be displayed as a metric label.

Circle through three points
Build a circle by tapping three points on the screen.

Build a triangle with the given two sides and angle between them
Just one more way to build a custom triangle. Available in the f(x) menu.

Golden section
Each segment or polygon side has ‘Show Golden Section’ property. If property is on then the golden section point of the segment is displayed.

Compass improvements
The compass now displays the distance between two points when in resizing mode. You can also input the radius manually by tapping on the distance label when resizing.

Calculator improvements
New features: backspace, copy/paste (long press), 1/x, x^y, inverse trigonometry functions (asin, acos, atan).

New sharing screen
Sharing got its own screen in the new version. In addition to the output format, you can now select the area of the document you want to share (image and PDF only). While in sharing screen, just drag the corners or sides of the cropping rectangle to select the area.

PDF export
PDF export was fixed to be truly vector now.

Geometry Pad 2.5.0

New version of Geometry Pad is available for download at the App Store.

Store Geometry Pad documents in your iCloud account. Sync documents with ease between all of your iPad devices. Especially useful with our new Geometry Pad for Mac. Switch between your Mac and iPad to work on Geometry Pad documents stored in iCloud.

Shapes List
Redesigned shapes window allows easily view the entire list of shapes in your document. Show/hide/lock/unlock shapes with a single touch. Edit the list to easily remove shapes you don’t need anymore.

And More
As always we keep working on fixing bugs and making minor improvements based on your feedback. Let us know if anything is missing and we’ll consider it for one of the future updates.

Geometry Pad for Mac

Today we are happy to announce that Geometry Pad is now available on Mac computers. Geometry Pad for Mac is based on the latest version of Geometry Pad for iPad and has all of the graphing features of the latter (except maps). In addition, it looks and feels like a standard Mac application. It takes full advantage of multiple document windows, fullscreen mode, printing, and iCloud. Try it today and let us know what you think!

Geometry Pad 2.4.7

Geometry Pad 2.4.7 is now available on Apple App Store. Here is what’s new in this version.

Export to Dropbox
It was already possible to save Geometry Pad documents to Dropbox. However, we received multiple requests to make it easier to export a document as an image or a PDF file to a Dropbox account. It is finally possible. Export to Dropbox works the same way as export as an image or a PDF. Just select the format and press the Share icon in the top right corner. The Dropbox button should be at the end of the list. Once the button is pressed, you can select destination folder and the file name.

Fill ellipses and sectors
As well as many other shapes, ellipses and sectors can be filled with a color now.

Autosave option
The Settings menu has new Autosave parameter. All changes are saved automatically when the parameter is On. However, sometimes you need to open a document, and make changes without saving them. In that case, you need to open the document and turn the Autosave parameter Off. You can now make changes and reload the same document without saving. Please note, that the Autosave parameter is automatically turned back On when you create a new document or open a different one. It is a safeguard against unintentional data loss.

Bug fixing and minor improvements
We keep fixing bugs and implement changes to make user experience as smooth as possible. Contact us through the Feedback form inside the app to share your opinions and ideas.

Geometry Pad 2.4.0

Today we are excited to introduce Geometry Pad 2.4.0. It brings a few new features, the most prominent of which are listed below.
It is now possible to insert a map into your document (premium feature)! You just need to select Import Map from the bottom menu and choose the region you’d like to import. The image of the map region will be inserted into the document and displayed below the grid lines by default. The following operations are available:

  • All object measurements are calculated in relation to the map scale. Device default units are used to represent the values: feet or meters.
  • Drag the map around your coordinate system. You can start dragging by using the tap-hold-drag gesture. Or, by tapping the map and selecting the Move Map command. Either way you’ll be able to change the location of the map image in relation to your coordinate system.
  • Move the map level up or down. You might need this feature if you want to display the map image on top of the grid lines or on top of all other objects. Both of the commands are presented when you tap a map.
  • The map is automatically saved into your document. Please note that the document’s size with a map will be noticeably larger than the size of the same document without a map.
  • The current scale is displayed in the bottom right or top right corner.
  • To delete a map just tap it and select Delete.

Here is what a document with a map looks like:
Geometry Pad with maps

An image can be imported (premium feature) the same way as a map. Working with images is very similar to working with maps. You can drag an image around, move it a level up or down, and draw geometric objects on top. Object measurements will still be calculated in logical units since an image doesn’t have any information about real world coordinates.

Math keyboard
It is now possible to input some of the math symbols when changing text annotations or metric labels. For now we chose the most important ones like angle, triangle, degree, squared, pi, square root, some greek symbols. But we’re looking to extend the selection. Please let us know what you think!

Edit triangles/quadrilaterals
It is now possible to change sides and angles in special triangles and quadrilaterals: right, isosceles, and equilateral triangles; and squares, rectangles, parallelograms, and rhombuses.

Full support of iOS 7
The Geometry Pad design was updated to match the iOS 7 theme. Please see the screenshot below:

Fall Update of Geometry Pad

Since it has been some time since the last update, we’d like to share our plans for the future versions of Geometry Pad.
Geometry Pad came a long way since version 1.0. We added a lot of new features, all based on our users feedback. We think it is now a good moment to step back a little bit and reshuffle Geometry Pad UI to make it even more intuitive and user friendly. For the past couple of months we’ve been working hard on the next major update. We’re making the user interface more straightforward, responsive and consistent looking. We are very pleased with what we’ve done already and hope to make the new version available in a month or two.
The new version will come as a free update to existing Geometry Pad users. It will probably also come with a price increase for new users. So now is a great time to purchase the full version!

Geometry Pad 2.0

We’re happy to announce that Geometry Pad 2.0 is now available in Apple App Store, Google Play and Amazon App Store. We’ve added many new features and made improvements that should make the app more user friendly. Please see the full list below.

Quadratics include hyperbolas and parabolas. You can create a quadratic curve by entering its equation. Each curve is fully customizable. You can change color, width and labels, and control other parameters like focus and special lines visibility. It is also possible to change a curve by moving its focus points or by moving the entire curve. And snapping works with curves as well. You can snap any point to a curve. You can also find intersections of a line with a curve.

Tangent lines
It is now possible to create a tangent line at a given point for the following shapes: circle, ellipse and quadratics. The tangent line is snapped to a shape and is adjusted automatically when the shape changes.

Metric labels
The Metric label is a text label with a computable value mixed in. For example, you can create a text label that contains an equation of a line. The label is updated automatically when the line changes. Almost every shape supports one or more kinds of metric labels. You can create your own by mixing different kinds together. For example, for a triangle you can create a label like “The area of the triangle ABC is {area} and its perimeter is {perimeter}”. {area} and {perimeter} will be replaced by triangle’s area and perimeter values.

Isometric dot grid
This is a different type of grid that helps with construction of simple 3d shapes built from cuboids. The feature is experimental and we’re looking for ways to extend and improve it in future versions.

Text styles
All text labels created with the Metric label or the Text tool can now be customized with a different font style (bold, italic, underlined) and size.

Better persistent snapping
We have made many improvements with persistent snapping. Your constructions now stay connected no matter what! And we made this feature available in the free edition of Geometry Pad.

Smaller improvements
We also made a few smaller improvements. For example it is now easier to scroll and zoom a document if you have many shapes on it. A touch will start interacting with a shape only if you hold your finger long enough. Otherwise it will be treated as a scroll/zoom gesture.

Please let us know what you think about the new version. And don’t hesitate to ask any questions.

End of School Year

The school year is coming to an end. It was the first school year for Geometry Pad. And Geometry: Constructions Tutor has only been around for a couple of months. Despite the short history of both projects, we’re quite happy with where we are right now. We’re humbled with the great amount of positive feedback we’re receiving from teachers and students. Thanks to user feedback, which has included requests for additional features, Geometry Pad has evolved with 9 major updates into something much more robust and useful than it was in the beginning.

We are also quite happy to see that more and more schools are adopting the iPad version of Geometry Pad. At least a couple of schools join every week. With recent news coming from the Google I/O conference, we are also very hopeful about the future of Geometry Pad for Android. Soon schools will get powerful tools for discovering and deploying educational apps on Android platforms. With affordable pricing for both hardware and software, the future of Android in schools is looking very bright.

We’re not planning to stop with these achievements though! The next major update of Geometry Pad is currently in development. Plenty of new features and improvements in the existing functionality are on the way, all based on requests from our users. The update will be released in the early summer on both iPad and Android. We hope that with the new version of Geometry Pad teachers and students will be well armed for another year of geometry studies!

Geometry Pad 1.8

We’re happy to announce that Geometry Pad 1.8 was released. This iterative update brings important features and changes that were requested by our users. The full list is below.

The compass tool is something you know from a geometry class. Simply put, it allows you to easily draw arcs. You can say that Geometry Pad already has arcs. It is true, but a compass is required in many geometric constructions that would be hard to replicate using just the Arc tool. Our compass is very easy to use. In fact, you just need one finger to move it around, rotate it, change the radius and draw arcs. Please take a look at the demo videos to see how it works. With the compass tool you can easily replicate all constructions from our Geometry: Constructions Tutor app.

Perpendicular bisector
You could already build perpendicular bisectors using the Midpoint property of a line and perpendicular snapping. However, a dedicated tool is nice to have because this element is widely used when making constructions. Just select the new tool and tap a line you need to build a perpendicular bisector for.

In Geometry Pad, vectors are just segments with arrows on the ends. In addition to that you can customize each segment or polygon side to have a different start/end style. It can be a circle, square, arrow or empty. You can also change all vertices at once from the Settings menu.

Line equation
Previously you could only input lines as a*x + b*y + c = 0. Now you can also input a line as y = a * x + b.

There are a few more improvements we made:
– All intersections are detected automatically and displayed as points. You can turn this off in the Settings.
– You can now display an angle value in a polygon for a given vertex. Just open the polygon properties and then go to the vertex properties.
– Double tap the screen to go back to (0, 0) location. It only works if coordinate axes are visible.
