Education made easy with Downy. Graph functions, create function tables, explore transformations, plot points, animate your graphs, and more.

Features:

* Graphing: Plot polar, Cartesian, or parametric graphs. There’s no limit to how many expressions you can graph at one time - and you don’t even need to enter expressions in y= form!

* Sliders: Adjust values interactively to build intuition, or animate any parameter to visualize its effect on the graph

* Tables: Input and plot data, or create an input-output table for any function

* Zooming: Scale the axes independently or at the same time with the pinch of two fingers, or edit the window size manually to get the perfect window.

* Points of Interest: Touch a curve to show maximums, minimums, and points of intersection. Tap the gray points of interest to see their coordinates. Hold and drag along a curve to see the coordinates change under your finger.

* Scientific Calculator: Just type in any equation you want to solve and Downy will show you the answer. It can handle square roots, logs, absolute value, and more.

* Inequalities: Plot Cartesian and polar inequalities.

* Offline: No internet access required. Great for classroom use!
