Skitch provides you with all the tools you need to visually communicate ideas, share feedback and collaborate with friends and co-workers. With Skitch on your mobile device, you can focus on what’s important in an image or PDF, mark it up with your thoughts, and pass it on.
Use an existing image or capture a new one, then add arrows, add shapes, or write on it with the pen or highlighter tool. Once you have added your ideas, share it with others to move your projects forward faster.
