FAQ: Apple AirTags for prepping

Of all of the products Apple released in 2021, perhaps the one that’s received the most press — for good and ill — is the AirTag, a small, cheap (for Apple), tracking device. The idea is that you slip it into a bag or attach it to your keys and you can easily track down the AirTag’s location with your iPhone. The other side of the coin is it’s feared to be a potent tool for stalking and auto theft.

What makes the AirTag different from Tile and other trackers?

The concept of a small, portable tracking device isn’t new. Ham radio operators have been using APRS for such devices for decades, and object tracking entered the mainstream with the Tile trackers. But what makes AirTag different is the power of Apple’s extensive Find My network. Tile trackers aren’t very useful because most of the time, it’s limited by the transmit distance of Bluetooth, about 30 feet. The AirTag also works by transmitting a Bluetooth signal, but it uses every nearby iPhone, iPad, and Mac with the right system requirements to relay the signal, and there are a lot of those out there in the wild — millions and millions. Tile has a similar networking technology, but the network isn’t anywhere close to as extensive.

To clear up some confusion: there is the Find My app on iPhones that you use to see the locations of devices, friends, and AirTags, and then there is the Find My network, which relays signals from AirTags and other devices.

The Find My network works silently in the background. If you have an Apple device, you won’t notice it being used. And the Find My network uses encryption and other technologies to protect your privacy from the devices relaying the signal.

How extensive is the Find My network? Kirk McElhearn mailed one to a friend and discovered that he could track it practically in real time. Every time the AirTag gets near a compatible Apple device, it relays its location to Apple’s servers.

How does an AirTag help me track objects?

The AirTag has three mechanisms to help you pin down its location:

  • It displays its approximate location on the map in the Find My appIt supports radar-like precision tracking on the iPhone 11 and laterIt features a small speaker that can be triggered from the Find My app to help you audibly track the AirTag

Do I need an iPhone to use an AirTag?

For all practical purposes, yes. You can view an AirTag on the map with the Mac and iPad versions of Find My (not the web version on iCloud.com), but you need an iPhone 11 or later for the precision tracking that helps you find the AirTag once you’re in the general proximity. You need an iPhone, iPad, or iPod touch to set up the AirTag.

Apple has considered what happens if a good samaritan without an iPhone finds your AirTagged item. There is an NFC chip built in that can be scanned with an Android phone, displaying your name, phone number, address, or whatever information you decided to share on the AirTag.

What can I use the AirTag to track?

Apple envisions you tracking things like backpacks, keychains, purses, and bicycles. In terms of preparedness, you can expand this a bit to things like:

  • Go-bags
  • Individual First-Aid Kits
  • Tool boxes
  • Ammunition boxes

Keeping an AirTag with your kits can help you find them when you need them and can’t remember where you put them. It may also help if your bag or other kit is stolen, assuming you’ve hidden the AirTag well and the thief isn’t actively looking for one.

There are creative uses for AirTag as well. An Army wife stuck one in her family’s stuff so they could track a moving truck. When the driver kept delaying and making excuses, she tracked the AirTag location to quickly figure out that he was full of it.

Can an AirTag be used for stalking?

There have been a number of media and police warnings about AirTags being used by criminals, including a model finding one in her pocket and people finding them attached to their vehicles.

Apple shipped the AirTag with a number of anti-stalking protections. Most notably, you’re alerted if an AirTag not registered to your iPhone is found nearby. It can lead to false alarms, like if you’re on a bus with someone who has an AirTag in their backpack. And it only works if you use an iPhone.


To help address this concern, Apple has shipped an Android app, called Tracker Detector, which doesn’t automatically detect foreign AirTags but lets you manually scan for them. Oddly, you can’t manually scan for AirTags with an iPhone and you can’t be automatically alerted of them with an Android phone.

Expect Apple to do more soon to address criminal usage of AirTags (and the bad press).

Can I share an AirTag with a family member?

Find My lets you track the locations of members of your Family Sharing group, as well as their registered Apple devices. That’s really helpful when, say, your spouse has lost their iPhone. Unfortunately, it doesn’t work that way with an AirTag. An AirTag is tied to a single Apple ID and isn’t shared. That can be really annoying if you borrow your spouse’s keys with an attached AirTag and get stalking warnings.

How long does the AirTag battery last?

Apple says the AirTag battery should last about a year. Amazingly for an Apple product, the AirTag takes a standard CR2032 battery that you can easily replace yourself.

How do I attach an AirTag to stuff?

The AirTag is a smooth disk without any holes or other ways to attach it to things. It’s easy enough to slip one inside a bag or box, but you need some sort of case to attach it to things like keys. Apple would like for you to buy one of their high-dollar designer AirTag cases, but there are cheap and perfectly serviceable AirTag cases on Amazon.

      I had not heard of these before so thank you for sharing!

      My first thought was having it on my escape artist dog so I can track her. Yes she has a microchip and a dog tag but last time she got out it was after a bath and didn’t have her collar on and in the 5 mins she was out was picked up, brought to a vet and they didn’t find the microchip. I found her via Nextdoor. Anyhow, I found online there are collars to hold the AirTag.

      Also if you are worried about tracking your vehicle if it was stolen, instead of using one of those trackers that requires a monthly subscription.

        That’s what I was thinking too. Place one in your vehicle, behind the foam of a gun case on an expensive gun, take apart your laptop and use some double sided tape to secure it in an empty space, etc… Make your gear easy to track if it gets stolen. At the price of $1 a year for a new battery, that is much cheaper than a monthly subscription.

        Good post.

        It would work for the dog IF it got lost in a relatively well populated area — aka places where people have iPhones that would be within Bluetooth range of your lost dog. If you live in a rural area, like we do, it wouldn’t have much value (or camping, etc).

        in regard to the stolen vehicle, see my comment below — that’s exactly what we did.

        I live near downtown in a hipster historic area that is also popular with tourists for the bars and restaurants, I think there are many iPhones around here 🙂

        But you are right, when I go camping this wouldn’t help at all.

      Thanks for the info! I looked into them prior to school starting to see if they’d work for tracking my oldest (elementary school) on the bus, but turns out they wouldn’t really work for that. We’ll probably end up getting him a smart watch at some point, but such a cost difference! Thankfully, his school has a tracker on the bus for parents, so we at least somewhat know where the bus is. We’re in a rural area, so it’s nice to know the route and approximately where they are.

      Several months ago my 2004 Ford F-350 was stolen from a grocery store parking lot. All my (very extensive) vehicle emergency supplies were in it of course. Neither the truck nor the emergency supplies were found.

      After I started doing research on how to be more secure in those categories. I came across the Apple AirTags that was. I bought one, tested it and was very happy with the results. I now have them on both of our vehicles and in our emergency kits. We’ve also got extras in case we need to “tag” the kids on some type of crowded event where they could get easily lost (post Covid of course, if that exists…)

      I’ve been using them for 3 months now and I think it’s a great product. Easy and intuitive to use pretty much across the board.

        Thanks for sharing your thoughts and experience with AirTags. I hope you never have to use them, but good that you have them in place in case you need them.

      SUCCESS UPDATE: After seeing the Air Tags on our dogs a<span style=”-webkit-tap-highlight-color: rgba(0, 0, 0, 0);”> </span>friend of ours thought it was a good idea to buy one for her Great Dane. Well today an incident happened that spooked the Great Dane and he ran off from the house. Her and neighbors immediately started looking for him but he ran off too fast. She then remembered to Air Tag and using the app she was able to find him right away. He ran off much further than expected in a short time and had even crossed a busy street. Without it she would not have been able to find him so fast.

      If anyone is curious on how it fits on a pet, this is my 14 pound dog. We have had this for about 6 months with no issues.

      This assumes that there is network connectivity.
