Apple AirTag 4 Pack Review: Four Trackers That Only Make Sense Inside An iPhone Household

Three ways to find a tag, and the network that costs nothing

An AirTag has three finding modes and they cover different distances. Up close, the Items tab in Find My plays a sound through the built-in speaker, which Apple rates as 50% louder on the second generation so it can be heard from up to twice as far.

In the same room or the same car, Precision Finding uses the Ultra Wideband chip to show distance and direction. The longer range, up to 1.5 times the original tag's, needs an iPhone Air or an iPhone 15 or later; Apple's shop-page footnote excludes the iPhone 16e and iPhone 17e. An Apple Watch Series 9 or Ultra 2 or newer on watchOS 26.2.1 can lead you to the tag from the wrist.

Everywhere else, the Find My network takes over. The tag's signal is picked up by any of the more than a billion iPhones, iPads and Macs that pass by, which relay its position to the owner while Apple says it protects privacy throughout, and no fee is charged for any of it. A lost item's location can be shared with more than 50 airlines, among them British Airways and Virgin Atlantic, and sharing stops when you are reunited with the item or after seven days.

Setup needs an iPhone or iPad, and Android gets alerts only

Apple's requirement line is short: an Apple Account and an iPhone on iOS 26 or an iPad on iPadOS 26. The shop page says 26.0 or later, while the spec table lists iOS 26.2.1 and iPadOS 26.1, so update first. No Android app is mentioned for pairing, so a household where the phone that will do the searching is not an iPhone has no way to use this pack.

Android phones are in the picture only on the safety side. If someone else's AirTag travels with an Android user, that phone can raise an unwanted-tracking alert, and after a while the tag itself starts playing a sound. Apple's instruction page puts the limit plainly: Find My network accessories "should not be used to track people, and should not be used to track property that does not belong to you". Within an iPhone household the reach is wider: a tag can be shared with up to five people, so the family car keys or the shared umbrella show up in everyone's Items tab.

A CR2032 you swap yourself, in an IP67 disc with no loop

The battery is the ordinary CR2032 3 V lithium coin cell, installed in the box and rated by Apple for more than a year of everyday use. When it runs low, an iPhone notification appears and Find My puts a Low Battery line under the tag's name. Replacement is a press down and an anticlockwise turn of the polished steel cover until it stops, a fresh cell dropped in positive side up, and the cover turned back until its three tabs line up with three slots. Apple adds one caution: some bitterant-coated cells, sold to discourage children from swallowing them, might not work with AirTag, so look for packaging marked compatible with it.

The disc measures 31.9 mm across, 8.0 mm thick, and weighs 11.8 g, with an IP67 rating for 1 metre of water for 30 minutes. There is no keyring hole, which is the design's one recurring annoyance: every tag needs a loop, a sleeve or a pocket. Apple's FineWoven Key Ring is £35 per tag, more than the £29 single it holds, while its store lists third-party four-pack holders at £39.95 for Belkin's strap holder and £49.95 for mophie's Loop case. The enclosure is 85% recycled plastic.

£17 saved over singles, one year of coverage, 14 days to change your mind

Apple UK lists £29 for one AirTag and £99 for four, so the four-pack saves £17 against buying singly. The shop page carries both figures next to the free engraving of initials or an emoji, which Apple marks as available only through itself. A holder is the real extra: four FineWoven Key Rings at £35 would add £140, which is why the four-pack holders at £39.95 and £49.95 change the maths more than the tag discount does.

AirTag falls under Apple's one-year limited warranty, which runs from the original retail purchase and lets Apple choose between repair, exchange for the same model or a refund; normal battery depletion is excluded, which for a device with a user-replaceable cell is unlikely to matter. Apple describes it as separate from and in addition to UK consumer law rights. Apple's UK sales policy allows a return or exchange with a receipt within 14 days of receiving the product, in original condition with its parts, accessories and packaging, and covers a price cut within 14 calendar days, excluding limited-time reductions such as Black Friday.

Skip it if the finding phone runs Android

The hard stop is the platform. If the phone that will hunt for the keys is an Android device, the four-pack is £99 of discs that cannot be paired, and the only thing they will ever do on that phone is warn its owner that someone else's tag is nearby. An iPad on iPadOS 26 can set them up, but nobody wants to carry a tablet through a station concourse, so treat this as an iPhone accessory and choose a tracker built for Android's network otherwise.

Pass on the pack, too, if the job is tracking a person; Apple states that Find My accessories should not be used for that, and its alerts are designed to defeat it. And if you lose one thing and one thing only, a £29 single is the sensible buy. The pack only earns its price when at least four objects deserve a tag and a holder each, which for most people means the luggage, the keys and whatever they leave in cafes.
