Is there a way for me to manage all the TV Shows I watch?

I watch a lot shows, around 15 right now. They’re all premiering and ending at different times. Is there any app or program (PC or iPhone) that could help me manage what nights shows are one, when a new season starts or stops etc. things like that? I’m a bit overwhelmed because my Comcast Cable box just got replaced and I lost all of my DVR series priorities so all of my shows are no longer being recorded automatically like they used to. Any help?
