Tivo app forces you to record what you watch??

Hi everyone, I just received my new Roamio Plus. I downloaded the Tivo app for my iphone with the hope I could watch live tv on it. I can do that but it also makes you record the channel you are watching. I don;t like that at all as it could use up space quickly. Is there a way to watch live tv without recording it? From the tivo website it states "Watch live TV or recorded shows anywhere".

Thanks for everyones help!!!
