That’s actually a pretty nifty idea. Too bad we live in a privacy nightmare and can’t trust others.
Perhaps this would be a good use for other connected devices like smart power meters.
It’s a private feature in the Weather app on iPhone.
To understand and improve the Weather app, Apple collects limited information about the first time you launch the app in a day. This information is not linked to your identity. If you allow Weather to access your location, your location will be sent to Apple to provide relevant weather forecasts.
You understand the photo is not from the default iPhone weather app, but from a completely separate app and service with a separate privacy policy “The weather channel”, right?
I do. That’s why I specified that same feature is private in the Weather app.
There’s no mention of barometer/fitness permission on Apple’s page, just location?
This is actually a really great feature. Dark Sky first started using crowdsourced barometric pressure readings to provide rain warnings. It provided a 10-minute warning for rain that was incredibly accurate. Living in NY, I got a 10-minute notification because someone 10-minutes southwest of me just got rained on.
Apple bought Dark Sky a couple years ago, and integrated the feature into the Weather app. The data is anonymized (hashed, encrypted, and relayed), so now it’s completely private.
It uses more power by leaving location services and barometric readings on persistently, but you can turn it on and off when you need it. It’s great for cyclists, runners, and hikers.
Phones come with barometers now?
I know when I’m looking for a new phone I pay special attention to make sure it has a state of the art barometer
If you have an android, check the Fdroid store, there are several apps that show you the raw output from every type of sensor on your device. I was surprised to find out several features on mine.
At least since iPhone 6ish? I think Dark Sky was one of the first apps to use it effectively. They’d aggregate the atmospheric data across it’s users to make hyper local weather predictions (i.e. “rain in 10 minutes”)
Yep, mostly just used to help crowdsource weather reporting like this.
Though I have seen another interesting use-case for the barometer, which is for IP-rated (water-resistant) phones, you can use the barometer to check that your device still has a water-tight seal with an app that measures the pressure as you squeeze the sides of the phone together.
I thought barometers were initially included to help with location. Air pressure isn’t just for weather, it also helps work out your altitude.
iPhone has had a barometer since 2014.
It’s a good idea. The watch I wear mountaineering is loaded with sensors, including a barometer. If my altitude hasn’t changed much, it alerts me of big pressure drops which means a storm is on the way. This is excellent when your side of the mountain is sunny and you can’t see or feel the wind from the massive system rolling in from the other side.
Great for camping in valleys too.
Why don’t you just feel the pressure drop in your bones? That’s what I do and I’m not even old.
I appreciate the rain in 10min. notifications, but there is no way I’d give an app access my sensors just for this, especially an app that is fully or partially ad subsidized. Is there a way to verify that it only accesses this one sensor?
They need to know your height so they can tell you how the weather is up there
