Simple Pregnancy tracker app for husband?

Has anyone found a good pregnancy tracker app for their husband?

Looking for an app with just the basics - calendar, baby size, general development benchmarks, etc

My husband is very involved and happy about baby, but does not need or want community/social media components to an app. He also doesn’t need all my health tracking info. I tell him when I don’t feel well or that morning sickness just started, etc.

What are you husbands or partners using to follow the pregnancy?
