Only Records Safari

I got this app, and at the top left corner, there was a camera icon. So I clicked on it and it recorded my screen, just that easily. So, I tried it again, and this time, I went to the home screen, and then I went back and clicked the camera icon, and it saved the video. Then, I go to my camera roll, and it didnt record me going to the home screen, all it recorded was Google, the website it starts on. So if you were to make gaming videos on your phone or iPad, you cant. It wont record the home screen.
