Description
Grafly is a revolutionary new graphing calculator for the iPhone/iPod Touch. Grafly provides full equation graphing interactivity, with live touch-based zoom and scroll features for arbitrarily complex multiple simultaneous graphs, and with live gravity mode for graph exploration by simply moving your device "around the figure" to view it from any angle.
Explore the geometrical beauty of mathematical equations with your fingers, as Grafly generates the visible portions of the equation in real-time.
"This was the first program that really made me realize the iPhone is a computing platform, not just a phone. Wow. A simply stunning program for rendering complex 3D surfaces. I would have to say it is superior in terms of manipulations and adjustments to a desktop program like Mathematica. ...." -- ursadog
"The best plotter on the app store, the 3d graphics are awesome, congrats. A very powerful math tool. 5 stars..." -- Rulo703797
FEATURES
• 2D/3D graphing of arbitrary, multiple equations with full shading, lighting, inside/outside distinction
• Cartesian, polar/cylindrical and spherical coordinate systems
• calculator for simple expressions
• touch-based and tilt-based exploration in 2D and 3D: rotation, translation, zoom in/out (pinch gesture)
• gravity-based exploration in 3D: see all sides of a figure by rotating your device
• real-time computation of equation surfaces in the background as you explore
• unlimited equation history with previous/next, delete, add, edit operations
• reset viewport: origin, orientation, zoom or all
• exploration modes: touch, gravity, tilt
• axes, grid (origin- or focal point-based), or all off
• full built-in help with mini-browser
• info display with helpful information
• calibrate "down" for gravity and tilt modes
• send equation via email for sharing
• show/hide navigation / tool bars for maximizing graph exploration screen space
• 30+ built-in sample equations for learning and exploration

"I for one am blown away by how well put together this application is." -- Azaezal
"The best 3d graphing app. Great quality and rendering of graphed surfaces. Easy to enter equations." -- mathematical maniac
"This app is so much fun to play with maths. This is the best graphical calculator EVER. Better than 2D/3D Graphing calculator. Very helpful for algebra problems and it's fun to model stuff with it." -- Animtv
What's New in Version 1.4
• conditional functions (if, and, or, xor)
• comparison operators (>, <, >=, <=)
• combination of conditional functions and comparison operators means you can control extent of graph to any level
• min, max functions now accept any number of parameters
• new gamma, secant, cosecant, cotangent functions
• rotating the screen no longer flashes currently-hidden toolbars, etc.
• minor bug fixes
• improved documentation
If you're upgrading, be sure to see the new sample equations using conditional operators.

Great app!
This is an amazing application for viewing mathematical equations. You can see all sides of a 3D graph simply by moving/rotating the iPhone. Well worth the money.
Not in Kansas anymore
This was the first program that really made me realize the iPhone is a computing platform, not just a phone. Wow. A simply stunning program for rendering complex 3D surfaces. I would have to say it is superior in terms of manipulations and adjustments to a desktop program like Mathematica. In terms of improvements, I would say a more dedication and specialized input interface would be nice, perhaps with a palette of common math and trig functions. I look forward to polar coordinates as well.
For me, this shows off the iPhone better than Koi Pond, albeit in a more geeky way, but is actually useful.
Version 1.2 as of this review.
Great 3d grapher
This program is awesome. It works great.
