Notability is an app for Apple devices that costs $8.99. This app allows users to do what Evernote and Skitch do, but with a wider variety of options. Much like Skitch and Evernote, this is a note taking app but also includes the capabilities of adding lines, grid, or dots to a paper, GIFs, images, video, etc. 

Skitch is an app that can connect to any curriculum. It is an app that allows someone to take an image or document and mark it using notes, drawing, and emojis. Skitch provides a variety of differentiating options as it allows writing, arrows, emojis, exclamatory punctuation, etc. It is incredibly easy to use with little introduction. Skitch is available for free on Apple products but is made by Evernote, which is available across platforms. Examples below are from a Latin II class and include annotated versions of a story and a story listening activity.
