Hey There i am developing a 4 screen app in which i want to show banner ads in my login page and my main screen and in my 3rd screen can anyone here help me with the full process. the app will also be published on google play and app store.
It seems you have just created a new account. You told us you were using Niotron. Show that you are using App Inventor. Until then I unlist this.
You can not use extensions when making an iOS app. It seems you have some reading to do. I never help with adding ads and it seems you are making a kind of earning app. Another reason not to help. Maybe some one else is willing to do that.
