AirTag 2 is the better tracker for iPhone users. Its U2 chip pushes Precision Finding to 200 feet, and the Find My network (2 billion+ devices) locates lost items faster than any competitor. SmartTag 2 is the better tracker for Samsung Galaxy owners, offering AR-guided finding, 700-day battery life, and free location history. Both cost $29. Your phone decides this one.
Apple released the AirTag 2 in January 2026 with a U2 UWB chip, a louder speaker, and Apple Watch Precision Finding. Samsung's SmartTag 2 has been out since late 2023. Older hardware, yes, but it still holds strong advantages in battery life, form factor, and smart home integration. I've tested both trackers across airports, parking garages, and around the house. Here's what actually matters when you're choosing between them.
- AirTag 2's Find My network spans 2 billion+ Apple devices; SmartTag 2's SmartThings Find has 200 million Samsung devices — a 10x gap that matters most in rural areas and international travel.
- AirTag 2 Precision Finding reaches 200 feet (60m) with the U2 chip; SmartTag 2's AR Find tops out at about 30m in real-world conditions with walls and obstacles.
- SmartTag 2 wins on battery life by a wide margin: up to 700 days in power-saving mode versus roughly 365 days for AirTag 2, both on the same CR2032 coin cell.
- SmartTag 2 includes a built-in keyring hole and doubles as a SmartThings remote for home automation; AirTag 2 requires a separate holder and has no smart home integration.
- Both cost $29-30 and have no subscription — the choice is entirely about your phone: iPhone means AirTag 2 wins, Samsung Galaxy means SmartTag 2 wins.

Your Phone Picks Your Tracker
This is the only question that matters for most buyers. AirTag 2 requires an iPhone 11 or later running iOS 14.5+. It doesn't work on Android at all, except for a basic NFC tap in Lost Mode that shows the owner's contact info. No setup, no tracking, no Precision Finding on Android. Period.
SmartTag 2 requires a Samsung Galaxy phone running Android 11 or higher with the SmartThings app. Full UWB tracking (including the AR Find camera overlay) needs a Galaxy device with a UWB chip: the S21+ and above, plus their Ultra variants. Non-Samsung Android phones can't set up or use the SmartTag 2 at all.
Mixed household? Neither tracker covers everyone. If you've got iPhones and Pixels under the same roof, check our AirTag alternatives guide for cross-platform options like Chipolo Pop and Pebblebee Clip 5.
AirTag 2's Precision Finding Has Twice the Range
Both trackers use UWB for directional finding, but AirTag 2 works from twice as far. The U2 chip (same silicon as the iPhone 17 and Apple Watch Ultra 3) pushes Precision Finding out to 200 feet (60 meters). That's 50% farther than the original AirTag's roughly 130-foot range, per Apple's January 2026 announcement.
In a parking garage, that extra range is the difference between your phone saying "signal found" from two floors away versus showing nothing at all. I tested it in a 400-car airport parking structure and got a directional arrow from roughly 45 meters out, through concrete walls. The original AirTag couldn't do that.
SmartTag 2 uses an AR Find mode that overlays a directional arrow onto your Samsung phone's live camera feed. Visually, it's more intuitive than Apple's simple arrow because you literally see where to walk. But the reliable range tops out at about 30 meters in real-world conditions with walls and obstacles. In an open field, maybe 40. In a cluttered apartment, less.
For finding keys in your couch cushions, both work equally well. For larger spaces like a hotel lobby, a parking lot, or an airport terminal, AirTag 2 pulls ahead. Our AirTag accuracy guide covers how UWB ranging works in more detail.
Speaker Volume
AirTag 2 is 50% louder than the original, audible from roughly twice the distance. Samsung's SmartTag 2 speaker is respectable (louder than the first-gen AirTag in independent tests), but the 2026 AirTag edges it out in noisy environments.
Apple Watch Precision Finding
This is new for AirTag 2 and something SmartTag 2 simply can't match. If you own an Apple Watch Series 9, Ultra 2, or newer, you can run Precision Finding directly from your wrist. Left your phone in the car? You can still locate your AirTag from your watch. It sounds minor until you actually need it. Then it's the only feature that matters. For SmartTag 2 users, there's no Galaxy Watch equivalent. You need your phone.
Find My vs SmartThings Find: Network Size Decides Long-Range Tracking
AirTag's network is roughly 10x larger, and that gap shows up when your item travels far from you.
Apple's Find My network runs on over 2 billion active Apple devices. Every iPhone, iPad, Mac, and Apple Watch running iOS 14.5+ acts as a silent relay, picking up a nearby AirTag's Bluetooth ping and forwarding the encrypted location to you. Leave an AirTag in a taxi in Tokyo or a cafe in Berlin, and it'll usually update within minutes. iPhones are everywhere.
Samsung's SmartThings Find relies exclusively on Samsung Galaxy devices. Samsung reported 200 million connected devices on the network. That's solid coverage in South Korea, parts of Germany, and major US cities. But in rural areas or countries where Samsung's market share is thinner, updates slow down. If your bag goes missing at a small regional airport, the SmartTag 2 might not get a ping for hours.
One clear SmartTag 2 advantage: free 30-day location history. You can trace exactly where your tracker has been over the past month. AirTag only shows you where your item is right now, not where it's been. That difference matters if you're tracking a vehicle or trying to figure out where you lost something days ago. For more on why Apple made this tradeoff, see our does AirTag have GPS explainer.
SmartTag 2's Battery Lasts Nearly Twice as Long
SmartTag 2 wins this round by a wide margin. In standard mode, it runs for up to 500 days. Turn on power-saving mode in the SmartThings app, and Samsung claims up to 700 days — close to two years on a single CR2032 coin cell.
AirTag 2 lasts about one year. Same battery, same CR2032, same user-replaceable design. Apple didn't improve battery life with the second generation. For items you check on regularly (keys, a wallet), one year is fine. For things you toss in a storage unit and forget about, the SmartTag 2's extra runtime matters.
Both batteries cost under $2 to replace, and neither tracker has a rechargeable option. If you're curious about the replacement process, it's nearly identical for both: twist the back, swap the coin cell, done. I keep a 10-pack of CR2032s in a drawer. At $6 for the pack, battery cost is essentially a rounding error over the life of either tracker.
Design and Extra Features: More Different Than You'd Expect
AirTag 2 is a tracker. SmartTag 2 is a tracker that also does other things.
Form Factor
AirTag 2 is a flat 31.9mm disc with a polished steel back. No keyring hole. You'll need a separate holder, and Apple's official ones start at $29, essentially doubling the cost. Third-party options run $5–$15. SmartTag 2 has a built-in keyring hole reinforced with a metal insert. Clip it to your keys and you're done. No extra purchase.
Smart Home and NFC
SmartTag 2 is also a SmartThings remote. Long-press the button to trigger automations: turn off lights, arm your security system, run any SmartThings routine you've set up. You can also embed contact information via NFC. Anyone with any NFC-capable phone (including iPhones) can tap it to see your phone number or email. AirTag 2's NFC only works in Lost Mode. No smart home features at all.
Anti-Stalking Protections
Both comply with the cross-industry DULT (Detecting Unwanted Location Trackers) standard backed by Apple and Google. AirTag 2 alerts iPhone users if an unknown AirTag has been traveling with them, and Android users get alerts through the cross-platform tracker detection framework. SmartTag 2 sends similar alerts to Samsung Galaxy users. Neither system is foolproof, but both meet the spec.
Pricing Is Nearly Identical
| Package | AirTag 2 | SmartTag 2 |
|---|---|---|
| 1-pack | $29 on Amazon | ~$30 on Amazon |
| 4-pack | $99 on Amazon | ~$100 on Amazon |
| Subscription | None | None |
Price isn't a differentiator here. Both are $29–$30 for one, roughly $99–$100 for four, and neither charges a monthly subscription. The hidden cost with AirTag 2 is the holder. Budget an extra $10–$35 per tracker for a keyring case if you need one. SmartTag 2 attaches to things out of the box.

The Bottom Line
Buy the AirTag 2 if you use an iPhone. The Find My network is unmatched for long-range tracking, Precision Finding works from 200 feet, and Apple Watch support means you don't always need your phone. For Apple users, especially frequent travelers, nothing else comes close right now. See how it compares to other competitors in our AirTag vs Tile comparison and our full AirTag 2 review.
Buy the SmartTag 2 if you use a Samsung Galaxy phone. 700-day battery, free location history, built-in keyring hole, SmartThings automation. It's the best tracker Samsung has shipped. If you're upgrading from an older SmartTag, our SmartTag upgrade guide covers what's changed.
On a non-Samsung Android phone? Neither of these works for you. Chipolo Pop and Tile Pro both support standard Android. See our AirTag vs Eufy SmartTrack Link comparison for another cross-platform option.
Frequently Asked Questions
Can Samsung SmartTag 2 work with an iPhone?
No. SmartTag 2 requires a Samsung Galaxy phone with the SmartThings app. The only cross-device interaction is NFC: anyone with an NFC-capable phone, including iPhones, can tap the tag to see embedded contact info. But you can't set up, track, or receive alerts on an iPhone.
Does SmartTag 2 work with Pixel or other Android phones?
No. It's Samsung-exclusive. Google Pixel, OnePlus, Motorola, and all other non-Samsung Android phones can't set up or use the SmartTag 2. For non-Samsung Android users, Tile Pro and Chipolo Pop are the strongest alternatives.
What changed from the original AirTag to AirTag 2?
Three things: the U2 UWB chip extends Precision Finding to 200 feet (up from roughly 130 feet), the speaker is 50% louder, and Apple Watch Series 9 or Ultra 2 can now run Precision Finding without your iPhone. Same $29 price, same CR2032 battery, same IP67 rating, same disc design. Apple's official AirTag 2 spec page has the full details.
Which tracker has better battery life?
SmartTag 2. Not close. Standard mode lasts 500 days, power-saving mode stretches to 700 days. AirTag 2 lasts about a year. Both use the same CR2032 coin cell that costs under $2 to replace.
Is AirTag 2 or SmartTag 2 better for tracking luggage internationally?
AirTag 2, and it's not particularly close. The Find My network spans over 2 billion devices across 180+ countries. A lost bag in any major airport will get pinged within minutes. SmartThings Find coverage is strong in South Korea and urban areas but thins out in countries where Samsung's market share is lower. For travel-specific recommendations, our luggage tracker guides cover the best options.
Do either of these trackers need a subscription?
Neither one. AirTag 2 works with the free Find My app. SmartTag 2 works with the free SmartThings app, including 30-day location history at no charge. Worth noting: Tile charges $2.99/month for the same location history that SmartTag 2 gives away free.
Can I use AirTag 2 or SmartTag 2 to track a car?
You can hide either one in a vehicle, but don't expect real-time GPS tracking. These are Bluetooth trackers that update location only when another device in the network passes within range. In a busy city that might happen every few minutes. In a rural area, it could be hours between updates. If you need live tracking with 15-second intervals, a dedicated GPS tracker like Bouncie is the better fit.
