It’s perhaps not a fully fledged fitness tracker, and it’s certainly not a smartwatch - but my favorite health tracking device has turned out to be my Oura ring.
I used it alongside my Apple Watch for quite a while, but I’ve found that the Oura ring gives me plenty of insight on my sleep, recovery and (more limited) activity. And the form factor is just awesome! I don’t even notice I’m wearing it, and I only charge it every 5 days or so.
I’ve stopped wearing the Apple Watch altogether now, and I find it freeing not to have all those notifications available on my wrist, while still having the health tracking I want from the Oura. Obviously it’s not a good fit for someone who does want the other features of a smartwatch, but solely as a health tracker I really like it.
Women aren’t a monolith, just as men aren’t. There are women who will appreciate your emotional openness, especially if you are able to regulate and communicate those emotions in a healthy way.
Edit to add: my relationship to my husband has only grown deeper as he has learnt to better access and express his emotions. In particular, he is working on accessing emotions other than anger, and this has really helped us grow our connection.
