Everything about Geometry Pad

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 2.4.7

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.

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.

Geometry Pad Pricing

In this post we’d like to address a very delicate issue of Geometry Pad pricing and uncover our strategy on pricing of apps in general.

Probably number one reason for one and two star ratings on Apple App Store and Google Play is that there is not enough free features in Geometry Pad. We totally understand users frustration when they download a free application just to discover that a lot of the features are premium only. It was made this way because Geometry Pad was never intended to be free. However, we strongly believe that users need to be given a taste of an application before they decide to buy it. Unfortunately, Apple App Store policies explicitly prohibit demo and trial modes for the published apps. So it was no way to go for Geometry Pad. As an alternative we had to create a free app that is actually useful and put all advanced features into the premium features pack. That way users get a plenty of free features to use, it complies with Apple policies and we have a source of revenue that allows us to sustain our small company.

That’s a related issue we’d like to cover. We are just a small development studio. We don’t have any external funding, we’re not a part of a big company or an educational institution and we don’t have a trust fund to live off. The price we charge for Geometry Pad is an essential source of revenue that is put back into the project and our team members. Being a paid application is the only way for Geometry Pad to survive. At least for now.

We’ve been working hard on Geometry Pad for over a year now and we feel like $5.99 is a fair price for the app. The price rose from $2.99 as we were adding more and more features. And it might rise again in the future. We don’t plan any price decreases as we believe it would be unfair to the users who already paid the full price and contributed into the project by spreading the word about it and giving us a great feedback.

As always, please let us know your thoughts in the comments below!

Plans for Geometry Pad

We are receiving a great volume of response from our Geometry Pad users. We feel very fortunate to have so much positive feedback and so many great, thoughtful users. We do realize that even though Geometry Pad has proven to be useful to a lot of students and educators around the globe, we still have some work to do. And we have big plans for the future versions.
First of all, we’d like to improve the features we already have. Fortunately, our users have plenty of good suggestions and that’s what we will focus on. Secondly, we’d like to implement more features to cover even more topics in geometry and calculus and to make Geometry Pad even more interactive, engaging and fun to use. In this case, we are not going to put just some random features in. We will add what is most asked for. Thankfully we already have a number of great candidates. Please let us know over e-mail or in comments below what are your suggestions!

And that’s our plans for the spring and summer of 2013!
