Drawing is one of those skills that I always wish I had mastered, but never quite got the hang of. I was at the head of my class in art until I hit tenth grade, but unfortunately, that's where I peaked, and it's been all downhill from there.
If your freehand skills aren't quite as good as you want them to be, the app SketchAR can help you fake it the rest of the way.
The app uses augmented reality to display something you'd like to draw onto a surface, then you can "trace" that image by looking through your phone or tablet.
While you certainly could use it to draw something on a piece of paper, this can particularly come in handy (even if your drawing skills don't suck) when you're trying to draw something like a mural on your child's wall or a sign for your store. Basically anywhere where going freehand might potentially get problematic.
SketchAR The app has a ton of templates built in, and for those who want to actually learn how to draw and not fake it, there's a section of the app with drawing lessons to help you get started.
It's not going to make you a world famous artist overnight, but it can help you momentarily up your game.
