We are in the line to the Keynote presentation. More news to follow.
By the way, if you want to talk to us, we are going to be at the iPhone Developer University Program Event this evening at the Franciscan Ballroom (Westin San Francisco Market Street, 50 Third Street)
An expression is a group of numbers, operators, variables, and functions or a combination of these elements. Now, go back to the new equation view, to plot a function simply enter: y=x^2 and tap the done button. If the expression contains an error, a message under the expression will appear informing about it.
If you unlock the advanced features you can graph implicit equations like x^2+y^2-5=0 or simply x^2+y^2-5 and Quick graph will assume that it is equals to zero.
You can use trigonometric functions, inequalities, and a set of prebuilt functions that we will explore in depth in subsequent sections.
It’s amazing to browse the iTunes AppStore looking for an app to download and finding your own App in the Staff Favorites section… We can’t describe the feeling, it’s great to be there.
The2.0.1 update is currently being reviewed by apple and should be available soon!
When we design Quick Graph we think to put in your hands a compact symbolic and numerical computer that will facilitate calculation and graphical analysis of problems. To fulfill that is necessary to have great arrange of math functions available to be used to plot 2D and 3D Graphs and calculation.
This great keyboard include the possibility of use the following variables: x, y, z, r, Θ, Φ and the constants: π, e
Note: square root should be typed as 2√x, or as x
√x
Quick Graph allows you to evaluate mathematical expressions that has variables as part of the expression.
With x=3, the expression 7x + 4 becomes 7 * 3 + 4 which is equal to 21 + 4 or 25. Figure 6 shows an example about how to evaluate an expression with a variable using Quick Graph.
Its important to notice that you have to enter the evaluation point first and then the equation, separated by a semicolon (;)
We left all of the functionality from the previous version free, but there are some changes to the interface that you need to be aware of. We did these changes to enhance Quick Graph capabilities.
The major change is that we removed the z=|y=|x= buttons and now you have to type these variables explicitly. For example, if before you selected z= and you entered the expression x^2+y^2, now you need to type z=x^2+y^2 to get the same result. Why did we do this? because Quick Graph is capable of much more now, so if you upgrade to the new “enhanced” version you will be able to graph expressions like z^2=x^2+y^2. This kind of expressions are called implicit equations, they allow you to make amazing graphs with Quick Graph!
Another change is that we removed the “Cartesian, Spherical, Cylindrical, Evaluate” buttons, but the functionality is all still there. You can type whatever expression you want and now Quick Graph will detect the type of coordinate system automatically.
Feel free to write us any suggestions or questions you may have with the new version of Quick Graph.
Quick Graph plots high quality 2D and 3D mathematical expressions. Graphs can be shaded with custom colors and in 3D the lighting is enabled to demonstrate the depth of the surface.
You can zoom in and out by pinching the image and pan around with one finger (2D) or two (3D). In both 3D and 2D modes, the graph adapts the evaluation limits when the touch gesture ends, allowing you to focus on specific features of the graph.
The 3D view allows for interactive rotation, translation and zooming by simple touch gestures. In addition, you can change from wireframe to solid visualization, with a simple double tap.
Quick Graph includes a wide variety of mathematical features and coordinate systems: Cartesian, Cylindrical and Spherical systems are supported for 3D equations, 2D equations support both Cartesian and Polar.
All graphs are automatically saved / restored whenever the application is closed / open.
Even though all the standard features that made the original Quick Graph a great app are free, you can opt to unlock additional features (via in-app purchase), these features currently include tracing, implicit graphs (2D and 3D), inequalities (2D and 3D), unlimited graphs (limited by the available device memory) as well as all other features that will be included in the future. Upgrading Quick Graph’s additional features will not only enhance your user experience, but it will also support the developing of Quick Graph!
Crazy Drops is a fast-paced addictive game that combines action and puzzle solving. With 12 increasingly difficult levels.
These drops are highly unstable creatures that can multiply out of control and eventually overcome our world. Luckily, connecting 4 or more drops of the same color will make them evaporate!
The game objective is then to keep your game area clear of drops and create chain reactions while at it.
In the spirit of retro style puzzle games like Candy Crisis, Bejeweled, Tetris and Puyo Puyo.
- 3 game modes, including One Player Game, Network Game and Solitaire Game.
- Play against the machine in One Player Game mode.
- Wi-Fi Multiplayer allows 2 players to connect via the same router on a Local Area Network in Network Game mode.
- 12 challenging levels.
- 4 drop styles.
- Colorful graphics.
- Groove along to 12 original music tracks or Listen to your own music while you play.
- Autosaves the current game if the application is interrupted (phone call)

A small application that simulates lasers going through prisms (objects capable of refracting, reflecting and decompose light) using Snell’s law.
When light travels from one environment to another, it changes velocity modifying its trajectory. The entry angle and the refraction indices of the prism and the environment determine the amount of light reflected and refracted, or if only one them will occur.
Just by moving the light source, you can calculate the entry and exit angles, you can use different materials for the environment or the prism, as well as different shapes.
Useful for those in the fields of physics/optics.
