Developed by Evernote, Skitch lets you annotate any photo, screenshot, or map you’ve captured on or imported to your tablet. You can find a location on a map, capture the map as an image, draw an arrow pointing to a desired meeting spot, add a text note — then share the annotated map with people you’re meeting. Evernote suggests taking pictures of people in a meeting, writing their names directly on the photo, and saving the snapshot to your Evernote account (which is linked to Skitch). Skitch also lets you share files via Bluetooth or Wi-Fi Direct or save them to apps installed on your device, such as Facebook, Skype, Picasa, Dropbox, and others.
