Annotate any Screen with Floating Draw
Do you often find yourself taking screenshots on your Android device? Have you ever wished you could easily draw on your Android screen in any app, and then take screenshots of that? While you can achieve the same by taking a screenshot first and then editing it using any of the countless photo editors available for Android, that adds a cumbersome additional step to the mix. Furthermore, if you need to add the exact same annotations over multiple screenshots, you’ll likely have to repeat the steps for each. XDA Forum Member ejezisek comes to the rescue with a handy app that simplifies it all for you.
Floating Draw is a small Android app that provides you with basic on-screen drawing tools that work anywhere in Android, regardless of what screen you’re on. Be it the home screen, the app drawer or any app’s screen, you can draw freehand, straight lines, and basic geometric shapes with this tool, and then save the resulting image(s). The app offers a bunch of colors to choose from, a paint bucket tool to fill the shapes you’ve drawn, and also an eraser to undo those strokes you made by mistake.
Not satisfied with the results at all? Simply hit the clear button and start over. Need to move to another screen? Hit the back button so that only the tiny pencil icon shows in the bottom-left corner, and navigate across the OS and between apps freely just the way you would normally. You can always get back to drawing mode by hitting the pencil icon again.
