A bit confusing

I just downloaded this app and it seems a bit confusing to me. Maybe that is because I just got it. It seems all over the place. On the main calendar it keeps adding a list of every single thing I do on the app and it is annoying. It feels like clutter and it serves no purpose. The settings dont allow me to change things that matter to me.
