Turn your drawings into animated GIF cartoons using this wonderful app. Folioscope includes powerful design tools such as a colour-specific eraser and an Adobestyle Paint Bucket tool, and this new version adds a choice of brush sizes. It’s very easy to use: draw your first frame using your finger or stylus, then draw the next frame on an overlaid layer. Keep going until you’re happy with your animation, then save it as a GIF. Our only disappointment is that the full-screen ads cost £ 1.99 to remove.
