Does OurFamilyWizard actually work or is it overpriced?

Been using it for 3 months after my buddy recommended it. Honestly? It's fine. The app works, the custody calendar is clear, and having a "journal" of all communication would theoretically help if stuff went to court. But it's $120/year and ngl I feel like a regular Google Calendar + email does 80% of the same thing. The main appeal seems to be if you need documented proof of conversations? Anyway, anyone else use it? Worth it or am I throwing money away?
