Skitch is a free app that helps you communicate visually with friends and co-workers. Annotate images with arrows, shapes, text, and more. Use Skitch to sketch something new, mark up maps, screen captures, or a photo and then send them to others.

Use Skitch to visually share your thoughts with others. Here are a few ways you can use it, too:

• Mark up photos of silly, cool, or inspiring things you see and share them via social, email, SMS, and more
• Annotate photos of your backyard to plan out your vegetable garden
• Share a diagram of the earth’s layers and have students label it with you
• Capture a map, mark it up, and share it with your friends to show them where you’ll be
• Open a PDF and highlight changes to skip the lengthy, confusing email chains and give clear feedback*

*Skitch’s PDF Markup feature requires either an in-app purchase or an Evernote Premium account.
