My project is TraceAR, an augmented reality powered app that helps you create drawings by supplying a virtual stencil. Just choose a stencil and it will lock onto your paper, you can then draw with your phone as a guide.
How much experience do you have? Does the project use anything you didn't create?
I am a beginner programmer, I have experience in a few programming languages and am now really getting into developing and competing in hackathons and coding competitions as such.
