A family member of mine recently got a cheap smart watch online. They weren't planning to use it with a phone app for privacy/security reasons. They thought using it without a phone would be fine, since they just wanted it for the time and for the health features like steps, blood pressure, blood oxygen, sleep tracking, etc. and didn't need to see their texts or other notifications on the watch.

Unfortunately, when we tested the watch, we found that basically all of the features required connecting to a shady no-name company's app. You couldn't even set the time! You can't set the time on a watch without an app!

Also, the watch was a bit bulky for their wrist, and they would prefer a slimmer one.

People of Tildes, do you know of any smart watches that allow you to use the health tracking features without ever connecting to a smartphone? If so, are there any that are slimmer instead of being bulky?

See device recommendation thread from 2019.

It's been a few years: tech has further matured, and we've gotten more things enshittified. With that in mind, I am asking these questions :

Edit: new comments very welcome as well! I wasn't on this site yet in 2019

(0) Did you find the device worth the money, what was surprisingly helpful or unhelpful? What was the tipping point into getting one and did it fulfil its promise?

(1) If your existing one broke today, would you still buy a new fitness tracker today?

(2) If yes, which one?

(3) Else no, why not, or what lessons have you learned since owning one, or what technological considerations do you have today that you didn't before?

Bonus: for folks who never had one, did you ever wanted one and if so what stopped you?

I'm in the market for a fitness tracker.

My usual fitness activities (stationary elliptical trainer, hiking, biking) are temporarily restricted, so I've been swimming a great deal. Using a phone isn't giving me adequate exertion tracking data for walking (stride counts and heart rate not available/accurate), and it's especially not useful for aquatics.

I'd be grateful if anyone can recommend something they have experience with.

My constraints are as follows:

I'd rather not contribute to e-waste with yet another gadget du jour - service life should be at least the recharge cycle life of the battery.

No Apple or Samsung devices. I'm not in those ecosystems, and don't plan to be because reasons.

Should be at least IPX5, preferably IPX7 waterproof.

Helps if it's not butt-ugly, but I'll take what I can get - replaceable bands are a plus.

Able to fit women - I don't have issues with a larger face so much as a band that's too large to fit comfortably or provide secure contact for accurate heart rate monitoring.

GPS and sleep tracking would be nice, but not mandatory if the device ecosystem isn't reasonably private.

Non-proprietary rechargers preferred.

A couple of Fitbit models seem be well-reviewed, but actual user ratings are equivocal, and quality is erratic.

Looking forward to any contributions!
