Yeah, and drop your iPhone, in a ruggedized case, into 3 inches of bath water for 5 seconds from a height of one foot and then realize apple's IP68 claim is laughable.

Yes, this happens to people all the time. The seals that keep water out degrade over time. New phones are generally ok, but heat, dirt, detergent/salt in water, etc. wear them down until they are not water resistant anymore. This is also why almost none of the manufacturers will fix the device under warranty when there is water damage, despite the IP rating. Even Apple themselvers recommend against submerging and iPh…

Cue to younger me that discovered the difference between water resistant and water proof when I found out that my "7 melodies electronic watch" didn't survive after a few minutes in the swimming pool. Will the UNA hint us with a little bit of fog on the window?

I too destroyed my "7 melodies electronic watch" back in the 80's by taking it for a swim at the beach .. man, that was so disappointing. Did get me on the CASIO Data Bank train, though ..

UNA is IPX5 rated, which means it is splash & showerproof to a high degree." If I had a dollar for every time some project that was ipx5 rated failed after getting caught in the rain one too many times...I'd have enough to buy another Garmin Fenix.

I really want to like this watch. Price is certainly right, and it does all of the things I'd want out of a Garmin or Apple Watch Ultra. But what problem does this solve for me? In the Apple Watch use case, a replaceable battery would be nice. But in contrast to Garmin, I've never replaced a Garmin because the battery wouldn't hold charge anymore. I've never broken a screen (if one has a habit of that, Garmin and App…

For me, I want an open API I can pull my data from. Last I checked, you have to be a business to use Garmin's API. Apple certainly doesn't let you. My goal is to have a cron that runs on my homelab that pulls my health data into a DB I own, from various sources, and visualize it in Grafana.

It's just a collation of sleep-end RHR/HRV. It's completely trivial and many manufacturers do this correctly; both are extremely reliable predictors of recovery metrics. Garmin has absolutely shitty sleep tracking but it doesn't matter; any wearable more or less nowadays can get static heart rate correct, leading to more or less accurate recovery metrics. "Collect every paper you can find on RHR/HRV/etc. recovery met…

How does HRV predict stuff like this ?
