I think what he means is that the iPhone dots seem to move based on vehicle acceleration and deceleration, whereas the android ones use all phone motion.
If I move my iPhone around in my hands the dots don't move, but on my android they do (ie are simulating a stable horizon as the phone tilts, immediately). I don't know which is more effective. I thought the iPhone one was broken at first and didn't have the best results from it, I'm hoping the less-subtle android ones will work better for me.
Edit: I read from the docs that Apple's works best when facing forward, and I was often sitting sideways on a train
That's strange, any idea how it could be able to differentiate?
My only guess is some sort of processing, like wait and see if it follows the expected acceleration pattern (moderate initial acceleration from the unexpected-to-the-user car motion, followed by a stronger acceleration in the same direction as one's hands push the phone to keep it in the same visual place) but I'd assume such lag is precisely the issue VR etc. has and makes people extra sick. By the time you've counteracted it, your brain has clearly registered that the movement is disjointed from the visual input, so then it's too late for them dots to help right?! That couldn't possibly work (or could it). Very curious how this works. Like, surely it doesn't need to be connected to a compatible car?
Edit: wait, or the camera. That would be very battery-intensive (I guess theoretically it could turn on only 1% of 1 color channel on the sensor, but I'm not aware that this is a mode that the hardware/firmware supports), but when you move it yourself, then the camera would see motion in the opposite direction as when you're unexpectedly being moved such as in a car. Still seems unlikely
It doesn't seem to actually differentiate at all. If I move my iPhone around on a plane (table), the dots move. If I hold in in my hand and move left/right, the dots move. If I hold it in my hand and raise/lower my arm, the dots don't move. That's actually just an integration of acceleration/gyro, and possibly combined with a simple model of how a phone is held (e.g. assume rotations happen from a point 30cm away from the bottom of the phone).
It works in a plane, so it’s somehow able to detect the higher rate of speed, maybe by integrating, but I think it does use signals from CarPlay as well.
They are using completely different approaches. Apple seems to be mostly using the accelerometer, to draw dots and visualize inertia. The Android apps are using the gyroscope, to draw a horizon.
One of the draws of mechanical watches compared to digital is that they, in theory, can always be repaired and will last a lifetime. In reality, not so much since the cost to do maintenance or repair is astronomical compared to buying a new watch, and one that does not have any surprise costs.
I had an automatic that was my "one and done" watch - a cheap Citizen diver - I wore it 24/7 until it started losing minutes per day. While looking into who or where I could fix it, I bought a G-Shock out of curiosity and never wore a mechanical watch again.
You should have said "to buying a new cheap watch".
The average cost of maintenance and worn-out parts' replacement for a self-winding Omega (worth 7k+) was about $800 in 2020, done once every 10 years.
The governments of Germany and Japan were completely destroyed, their nations were then occupied and then rebuilt to be friendly to the US and other Western nations to fight against communism.
But here, Iran's government has not been overthrown nor their nation occupied.
Sunscreens that use zinc/titanium dioxide as active ingredients are often so unpleasant to use that people don't apply enough of them or refuse to use them. The "nicer" sunscreens that use these ingredients often sneak in SPF boosters which are actually derivatives of other chemical sunscreens but are treated differently on the ingredients label, pretty much cheating the system.

Interesting, thank you for pointing this out. I had a little trouble understanding what the link was saying at first, but it seems to (correctly) state that many "mineral" sunscreens contain active chemical ingredients like butyloctyl salicylate. (And they're sometimes labeled as non-active ingredients?)
There's an interesting trend of some cars having their daytime running lights and their low beams in completely separate positions, with the car design only emphasizing the former. This effectively reduces the height of the headlight even if the car is taller. Here's an example:

I've tried some of those Android equivalents and they seemed to work on any motion, not on acceleration like the Apple one.
