Glow Nuture is pretty neutral since it has an option for you to be invited by your partner and both of you have access to the same data. It's got the same stuff as Baby Bump Pro with the "your baby is this big" comparisons, articles and tips on a week-by-week basis, that sort of thing.
The big difference is it allows you to track lots of things (sleep, exercise, vitamins, water, mood, symptoms, etc.) and then gives insights based on those. The Premium mode gives access to more and more personalized insights, but the basic ones looked pretty good from my playing around with it.
