Many users reported that their altitude was calculated 200 to 300 meters too high, despite the fact that affected devices had worked correctly in the past. Users on Apple’s German support forums found that a period of low air pressure was causing the Apple Watch’s altimeter to give incorrect altitude readings.

How does Apple Watch know elevation?
Apple says that its updated altimeter cross-references information from GPS and nearby Wi-Fi networks to detect even the smallest changes in elevation above ground level, up and down to the measurement of 1 foot.
How does Apple Watch measure altitude?
A narrow cone indicates better accuracy than a wider cone. Rotate the Digital Crown up to see your elevation, incline, and coordinates. To see your direction at a glance and open the Compass app with a tap, add the Compass complication to your watch face.

Is Apple Watch 6 heart rate accurate?
However, research has found that this accuracy rate is only about 34% overall, and further studies are needed to confirm when the Apple Watch heart rate monitor is most useful.
Why does my Apple Watch not track elevation?
On your iPhone, go to: Settings > Privacy > Motion & Fitness – check that both Fitness Tracking and Health are enabled. On your iPhone, in the Watch app, go to: My Watch > Privacy – check that both Fitness Tracking and Heart Rate are enabled.
How elevation gain is calculated?
Elevation gain is the total amount you will climb in a day, and elevation loss is the total amount you will descend in a day. For example, if you climb 1000 feet, descend 500 feet, and then climb an additional 300 feet, the elevation gain would be 1300 feet and the elevation loss would be 500 feet.
Does Apple Watch 6 have Barometer?
Apple Watch 6 – Barometer
During your adventure, you have another use for the barometer. If you are stationary over an extended period then changes to air pressure could indicate an approaching storm. So you have to think of your Apple Watch as able to separate changes to elevation from changes in air pressure.
How do altimeters work?
The altimeter measures the height of an aircraft above a fixed level. The instrument senses this by taking the ambient air pressure from the static port. … As the aircraft goes up, the pressure inside the case decreases and the bellows expand. The opposite happens as the aircraft descends.
Does Apple Watch 3 have altimeter?
There is no built-in altimeter app for Apple Watch Series 3. The watch can use its barometric sensor to calculate elevation gain during workouts and to track flights of stairs climbed during general daily wear.
