body: I plan to create a video to promote my idea for an app. Quite similar to how Google's Pokemon Challenge Video turned into Pokemon Go. I would like people to see how my app would look like and how it can be used when it is finished. I guess I am a little paranoid on people actually copying my idea. Do I have to get a copyright for my idea or can I do something else?
