Best Apple AirTag Accessories
Looking for the best key ring or holder for your new AirTags? There are plenty of options, starting at well under $20.

You should buy an Apple AirTag if you’re notorious for losing wallets, phones and other personal belongings. AirTag accessories, like the best AirTag holder, key chain or collar, are must-haves for anyone who wants to make use of Apple’s nifty tracking devices. The leading Tile competitor, Apple’s AirTag helps you to track down important objects like bags, keys, wallets or whatever you attach your AirTag to. Just open up Apple’s Find My app. It’s a boon if you misplace things often. A single AirTag costs $29 (£29, AU$45), though you can get a four-pack for $99 (£99, AU$149).
The main downside is, AirTag discs don’t come with any kind of holder. This means, depending on how you plan to use it, you’re going to need some sort of accessory for what’s also, basically, an accessory. (Apple has a tendency to spur its own cottage industries for add-ons, even though they’re accessories to begin with — AirPods are a perfect example of this.) However, you can find tons of AirTag accessories in multiple styles for any budget.
In some cases you’ll be able to embed an AirTag into an object sans holder — just pop it in a purse or backpack, for instance — but some people like to keep an AirTag with their keys or attach it to a backpack or laptop bag. You may also want to stick your AirTag onto an object and plenty of AirTag mounts are available.
Note that CNET editors have tried most but not all of these accessories. If we haven’t tried a product, we’ve tested other accessories from those companies so we feel comfortable recommending them. We’ll be adding more AirTags accessories to the list as we test new products.

Key chains and straps
Belkin
Belkin’s Secure Holder for AirTags comes in key-ring or strap versions in four color options. There’s nothing terribly fancy about them, but at $11, they both cost less than Apple-branded options shown below. You can also get a two-pack for $20.

While it launched a little later than some AirTags accessories, Otterbox’s key chain holder, which Otterbox calls a «Rugged Case,» is made of solid plastic and does indeed encase your AirTag (you unscrew the top piece, place your AirTag in the case, then screw the top piece back on to lock the AirTag in the holder). It’s available in black or white for $20 but is currently on sale for $15.
Amazon
While this faux leather key chain from Cyrill, a sub-brand of Korea-based Spigen, is nothing fancy, it’s currently available in stone and black color options.

The Apple-branded leather key ring costs $35 and comes in three colors: black, saddle brown and red.
Amazon
If you’re looking for a value option, your best bet may be to roll the dice on a no-name brand on Amazon. This Eusty key chain cover is available in a four-pack for just less than $15. Often, generic models like this are labeled as «leather» when in fact they are faux leather (sometimes referred to as PU leather or vegan leather). These look a lot like other basic faux leather AirTag key chains and come in a few color options.
There are dozens if not hundreds of generic AirTag holders available. Most should be fine, but don’t expect them to wear as well over time as the true leather models.
David Carnoy/CNET
Caseology’s AirTag Vault is another straightforward key chain option that’s affordable at $15 but could shave a few dollars off its price over time. (Caseology is also a sub-brand of Spigen.) It’s one of the few AirTag accessories that was available at launch and has been pretty popular as a result. It comes with a carabiner but you could attach a standard key chain if you wanted. It should be back in stock fairly soon.
Amazon
Spigen is also selling an attractively simple key-chain AirTag holder, the Valentinus, for around $18. It’s made of faux leather. Alas, it’s temporarily out of stock but should be back in the next few weeks.
Amazon
If you’re looking for a holder that sticks onto an object (like the underside of a bike seat or scooter), Pelican’s Stick-on AirTag Mount is designed to do just that. A single mount costs $16 while a pack of four sells for $30. It’s available in four different colors.
Apple
Apple’s Loop, made for attaching your AirTag to a bag, costs as much as an AirTag. But it’s Apple’s official loop option and this polyurethane option is cheaper than the leather $39 Leather Loop. (That doesn’t make it a good deal, but I’m just pointing it out.) It’s available in four different colors.
Nomad
I like the design of Nomad’s leather AirTag key chain better than Apple’s, which leaves the AirTag partially exposed. This AirTag key chain hides it and looks more like a standard key chain. It’s designed to «weather» over time, getting darker (particularly the brown version). It’s available in brown or black for $30, which is pricey but it is nice.
Nomad also makes a Leather Loop that’s also a key chain and lists for $20. I prefer the more expensive model pictured here.
Spigen
Spigen, known for its value iPhone cases, has its AirTag Case Rugged Armor ($16). It’s not quite as cheap as we hoped it would be, but maybe it will come down in price in time. It does have a rugged design with a nice carabiner and carbon-fiber elements.
David Carnoy/CNET
Casetify has a wide variety of AirTag holders. They’re made of hard plastic and are fairly basic but have some eye-catching art on the backside. You can also customize them with your name or choose from several emojis and other graphics. They’re expensive at $38 but sometimes go on sale.
Nomad
If you’re looking to AirTag your pet, Nomad’s upcoming Rugged Pet ID Tag fits the bill (Nomad’s AirTag key chain is essentially identical). According to Nomad, it’s constructed with a TPU-overmolded polycarbonate shell and comes with two enclosure options: an IP67 waterproof back and a speaker-hole back. For an extra $20, you can buy a customizable stainless steel insert cover that you can get engraved with your pet’s name and a way to contact you. No pet collar is included.
It’s worth bearing in mind that Apple says AirTags are not designed to track pets. Your pet would need to be within range of the Find My network for the AirTag to work, so if it runs off into the woods it won’t be much help.
Other AirTag options
Moment
Moment, which makes and sells photo and video accessories for Apple products, including lens attachments, will have an enclosure accessory that allows you to mount your AirTag. «Made from a rugged aramid fiber shell and backed with a super strong adhesive, you can stick an AirTag to any flat surface,» Moment says.
Moment also has to other mounts: The Curved Surface Mount for AirTags ($25) that’s made out of flexible silicone (rubber) and can adhere to surfaces that aren’t totally flat; and the Stretch Fabric Mount for AirTags ($25) that’s designed to stick to fabrics, such as the inside of a bag, and other flat surfaces.
Amazon
If you don’t want to spend $15-$20 for a mount, these Gorilla Mounting Tape Squares are a cheaper option at $6 and can be cut to size for AirTags. AirTags have an IPX67 water-resistance rating, which means it can be fully submerged in up to 1 meter of water for 30 minutes and is dust-proof. So it can withstand some punishment without a cover. After all, it doesn’t have a screen.
Amazon
The AirTag uses a CR2032 coin battery, which should last about a year. You can find a 10-pack of those batteries on Amazon for less than $10. That’s the way to go, especially if you have multiple AirTags, and other devices that use CR2032 coin batteries.
Always remember to keep coin batteries away from small children so they don’t accidentally swallow one. They can cause major injury if ingested.

Apple, I’m (Sky) Blue About Your iPhone 17 Air Color
Commentary: The rumored new hue of the iPhone 17 Air is more sky blah than sky blue.

I can’t help but feel blue about the latest rumor that Apple’s forthcoming iPhone 17 Air will take flight in a subtle, light-hued color called sky blue.
Sky blue isn’t a new color for Apple. It’s the featured shade of the current M4 MacBook Air, a shimmer of cerulean so subtle as to almost be missed. It’s silver left too close to an aquarium; silver that secretly likes to think it’s blue but doesn’t want everyone else to notice.
Do Apple employees get to go outside and see a real blue sky? It’s actually vivid, you can check for yourself. Perhaps the muted sky blue color reflects a Bay Area late winter/early spring frequent layer of clouds like we typically see here in Seattle.
«Who cares?» you might find yourself saying. «Everyone gets a case anyway.» I hear you and everyone else who’s told me that. But design-focused Apple is as obsessive about colors as they are about making their devices thinner. And I wonder if their heads are in the clouds about which hues adorn their pro products.
Making the case for a caseless color iPhone
I’m more invested in this conversation than most — I’m one of those freaks who doesn’t wrap my phone in a case. I find cases bulky and superfluous, and I like to be able to see Apple’s design work. Also, true story, I’ve broken my iPhone screen only twice: First when it was in a «bumper» that Apple sent free in response to the iPhone 4 you’re-holding-it-wrong Antennagate fiasco, and second when trying to take long exposure starry night photos using what I didn’t realize was a broken tripod mount. My one-week-old iPhone 13 Pro slipped sideways and landed screen-first on a pointy rock. A case wouldn’t have saved it.
My current model is an iPhone 16 Pro in black titanium — which I know seems like avoiding color entirely — but previously I’ve gone for colors like blue titanium and deep purple. I wanted to like deep purple the most but it came across as, in the words of Patrick Holland in his iPhone 14 Pro review, «a drab shade of gray or like Grimace purple,» depending on the light.
Pros can be bold, too
Maybe the issue is too many soft blues. Since the iPhone Pro age began with the iPhone 11 Pro, we’ve seen variations like blue titanium (iPhone 15 Pro), sierra blue (iPhone 13 Pro) and pacific blue (iPhone 12 Pro).
Pacific blue is the boldest of the bunch, if by bold you mean dark enough to discern from silver, but it’s also close enough to that year’s graphite color that seeing blue depends on the surrounding lighting. By comparison, the blue (just «blue») color of the iPhone 12 was unmistakably bright blue.
In fact, the non-Pro lines have embraced vibrant colors. It’s as if Apple is equating «pro» with «sophisticated,» as in «A real pro would never brandish something this garish.» I see this in the camera world all the time: If it’s not all-black, it’s not a «serious» camera.
And yet I know lots of pros who are not sophisticated — proudly so. People choose colors to express themselves, so forcing that idea of professionalism through color feels needlessly restrictive. A bright pink iPhone 16 might make you smile every time you pick it up but then frown because it doesn’t have a telephoto camera.
Color is also important because it can sway a purchase decision. «I would buy a sky blue iPhone yesterday,» my colleague Gael Cooper texted after the first rumor popped online. When each new generation of iPhones arrive, less technically different than the one before, a color you fall in love with can push you into trading in your perfectly-capable model for a new one.
And lest you think Apple should just stick with black and white for its professional phones: Do you mean black, jet black, space black, midnight black, black titanium, graphite or space gray? At least the lighter end of the spectrum has stuck to just white, white titanium and silver over the years.
Apple never got ahead by being beige
I’m sure Apple has reams of studies and customer feedback that support which colors make it to production each year. Like I said, Apple’s designers are obsessive (in a good way). And I must remind myself that a sky blue iPhone 17 Air is a rumored color on a rumored product so all the usual caveats apply.
But we’re talking about Apple here. The scrappy startup that spent more than any other company on business cards at the time because each one included the old six-color Apple logo. The company that not only shaped the first iMac like a tipped-over gumdrop, that not only made the case partially see-through but then made that cover brilliant Bondi blue.
Embrace the iPhone colors, Apple.
If that makes you nervous, don’t worry: Most people will put a case on it anyway.

Astronomers Say There’s an Increased Possibility of Life on This Distant Planet
Using the James Webb Space Telescope, astronomers are working to confirm potential evidence of life on a distant exoplanet dubbed K2-18b.

Astronomers are nearing a statistically significant finding that could confirm the potential signs of life detected on the distant exoplanet K2-18b are no accident.
The team of astronomers, led by the University of Cambridge, used data from the James Webb Space Telescope (which has only been in use since the end of 2021) to detect chemical traces of dimethyl sulfide (DMS) and/or dimethyl disulfide (DMDS), which they say can only be produced by life such as phytoplankton in the sea.
According to the university, «the results are the strongest evidence yet that life may exist on a planet outside our solar system.»
The findings were published this week in the Astrophysical Journal Letters and point to the possibility of an ocean on this planet’s surface, which scientists have been hoping to discover for years. In the abstract for the paper, the team says, «The possibility of hycean worlds, with planet-wide oceans and H2-rich atmospheres, significantly expands and accelerates the search for habitable environments elsewhere.»
Not everyone agrees, however, that what the team found proves there’s life on the exoplanet.
Science writer and OpenMind Magazine founder Corey S. Powell posted about the findings on Bluesky, writing, «The potential discovery of alien life is so enticing that it drags even reputable outlets into running naive or outright misleading stories.» He added, «Here we go again with planet K2-18b.Um….there’s strong evidence of non-biological sources of the molecule DMS.»
K2-18b is 124 light-years away and much larger than Earth (more than eight times our mass), but smaller than Neptune. The search for signs of even basic life on a planet like this increases the chances that there are more planets like Earth that may be inhabitable, with temperatures and atmospheres that could sustain human-like lifeforms. The team behind the paper hopes that more study with the James Webb Space Telescope will help confirm their initial findings.
More research to do on finding life on K2-18b
The exoplanet K2-18b is not the only place where scientists are exploring the possibility of life, and this research is still an early step in the process, said Christopher Glein, a geochemist, planetary researcher and lead scientist at San Antonio’s Southwest Research Institute. Excitement over the significance of the research, he said, should be tempered.
«We need to be careful here,» Glein said. «It appears that there is something in the data that can’t be explained, and DMS/DMDS can provide an explanation. But this detection is stretching the limits of JWST’s capabilities.»
Glein added, «Further work is needed to test whether these molecules are actually present. We also need complementary research assessing the abiotic background on K2-18b and similar planets. That is, the chemistry that can occur in the absence of life in this potentially exotic environment. We might be seeing evidence of some cool chemistry rather than life.»
The TRAPPIST-1 planets, he said, are being researched as potentially habitable, as is LHS 1140b, which he said «is another astrobiologically significant exoplanet, which might be a massive ocean world.»
As for K2-18b, Glein said many more tests need to be performed before there’s consensus on life existing on it.
«Finding evidence of life is like prosecuting a case in the courtroom,» Glein said. «Multiple independent lines of evidence are needed to convince the jury, in this case the worldwide scientific community.» He added, «If this finding holds up, then that’s Step 1.»
