I just discovered my iPhone "compass" app. [View all]

It seems reasonable to assume the feature is not a magnetic compass. I'll have to investigate the magic of the device.

If it's not a magnetic compass, the iPhone does not correct for global magnetic declination. The iPhone displays true north.

If it's not a magnetic compass, any local magnetic attraction is irrelevant it the iPhone's directional display.

Am I understanding this device correctly?

So it does. And subject to local attractions, as well. WheelWalker Apr 2023 #5

That's how non-digital, "real" compasses work - they indicate magnetic north. Ocelot II Apr 2023 #12

It also has an altimeter and your gps location... ret5hd Apr 2023 #2

So it is. I would never have imagined so. How bizarre. WheelWalker Apr 2023 #6

It's easier to measure with a couple magnetic coils Jerry2144 Apr 2023 #8
