To be clear, with the default OS, you don't get true 24/7 heart rate tracking. You can simulate it though by turning the heart rate monitor "app" on and backing out of it without stopping it, and then make sure you have the wake on movement options enabled.
The pinetime is a very basic smart watch. It is not fancy in any stretch of the imagination. It shows the text of notifications only, does very basic heart rate monitoring, and you have to manually go into a different "app" to do multimedia controls. You'll notice I'm saying app in quotes. They're more like built-in function menus, you can't install new apps.
But despite all that, I have never had a watch this refreshingly good to use. I have had 2 WearOS watches and work gave me a demo Apple Watch to show customers. All of them were nice, but all of them had that enshittification ooze leaking out of them.
Pinetime is simple. It works. It simply works. And for that, I love it.
Oh and the week-long battery is nice too.
True programmers know that novice code is a rite of passage. Every programmer worth their salt looks at their own older code and cringes at it. Most people who do this for a living are more likely to give helpful pointers rather than tear you down, if anything.
If someone is being a jerk to you about your code, stop listening to them immediately and walk away or block them.
