iDoodle2 utilizes the power of the iPhone's advanced graphics and UI to create a great drawing app that's easy and fun to use. You can draw a wide array of shapes and text with a full spectrum of colors, gradients, and fonts with alpha support. Sketch these shapes on top of any photo from your library, iPhone camera, or a custom gradient. You can save your doodles to work on later and replay, or you can export your images to the photo library. Full undo/redo is supported through a novel use of the accelerometer. Other tools include a soft brush, eraser, and an eyedropper tool to pick colors from your image. The new version implements multi-touch zoom, a smart offset tool, and a simplified kid mode. Have fun with iDoodle and make some great (or even not-so-great) art!
