I actually couldn't find another option that would allow me and my spouse to share and have full access to each other's "fitness analytics". I know MyFitnessPal seems to be popular and there are other apps and stuff, and I'll admit that I didn't actually try every one of them. I understand that for some of these services, sharing full data with another person would probably just be an additional feature, but for my purposes it would be the main source of value. Anyway, if you know of any solutions that do this, I would love to hear, because I would start using it today with my spouse.
As far as doing different kinds of fitness activities, I totally agree and never intended to give the idea that people would have to engage in the same activities. It took my quite a while to figure out what I enjoy and found to be sustainable, and I can definitely appreciate diversity in this area.
I really do appreciate your feedback. Thanks again!
