ScreenDraw provides an easy way to draw on your screen and over any application(s).
Many times I want to show people directions using the google maps app but not with directions provided by google and instead with my own directions.
There was no simple way to do this which is why I made ScreenDraw.
ScreenDraw is a service that gives you an icon which will always be visible (unless you stop ScreenDraw via the notification menu). When you click on the icon you enable drawing mode and you can draw anywhere on your screen with different colors via the color picker and different stroke widths.
This way I can draw directions on the google maps app (or any other app) and take a screenshot or just show it to others.
This app is uses this open source library https//github.com/premnirmal/Magnet
