It really is a family tracking app. Very likely designed initially to track people with dementia that are still capable of living independently. My neighbours needed to track the elderly man that lives across from me because he didn’t respond to his early morning call. He has early stage dementia, and is usually fine. He just has very occasional times when he can get lost. Of course for this app to work, you’d have to have your phone on you.
I could also see it being used as a safety measure for older children, even adults under certain circumstances where they might become lost/injured eg hikes, dirt bike/quad riding, traversing remote areas etc. I’d imagine it’s a tracking app that can be activated/deactivated by any user. Companies, even places like nursing homes, have used tracking apps for years as safety measures. It’s not always about control, but in the case of Amber and Co it is absolutely about control. Guaranteed if they deactivated it for any period of time, they’d be reamed once they were home or in contact again.
Most people’s cars these days have telemetrics that can be tracked. Then there is face recognition cameras. Many people just don’t realise how much of an eye is on us at all times. Watch a season of Hunted, it’s incredibly eye-opening.
