Freezit !
Freeze your screen and annotate it with this productivity app.
Tap the “+” button in the top right corner to get things started. You’ll see a row of seven icons that indicate all of the ways you can capture and import content to mark up. For example, tap the map icon to launch Google Maps within Freezit, enter a location, and tap the pencil icon in the top right corner to draw right over the top. Repeat the process to mark up calendars, photos, documents, and even web pages. All of your captured and marked up content can be found on the main screen, and you’re able to filter it and search for specific entries. The app also includes iCloud support.
