Just A Line is an app developed by Google Creative Labs that lets you draw on your screen using augmented reality technology. Focus your Android smartphone's camera and then draw on whatever you see on the screen. Once you've drawn something, you can even record a video.
That said, you don't have many options to choose from when it comes to drawing. All you can do is change the width of the stroke and undo a line if you make a mistake. That's it. After that, you can record a video of what you created.
Just A Line is an interesting app thanks to which you can create simple but surprising videos in augmented reality. Why not give it a try?
