So I am in the process of finishing an app (android for now), and I have a doubt about if I should have papers that proof that I made that app.
Its the first time for me to publish an app, and I am concerned about how to prove that I made the app and it belongs to me.
In other words
If I came and asked the instagram app developer, prove that you made this app? What would he show me?
Thanks for your help.
EDIT
So developers of whatsapp, instagram, skype, ...... have nothing to prove that they made the app? They just publish to the store?
