The best Bluetooth trackers for Apple and Android phones

适用于苹果和安卓手机的最佳蓝牙追踪器

For those of us who don’t ever seem to know where our keys or wallets have gone. 对于那些似乎永远不知道钥匙或钱包丢到哪里去了的人来说。

Some people rarely lose things. Wallets are always exactly where they’re supposed to be, keys never go missing, and remotes never slip between the couch cushions. And then there’s the rest of us — the folks who can’t ever seem to find the thing that was right there a few seconds ago. For us, Bluetooth trackers can help. 有些人很少丢东西。钱包总是放在该放的地方，钥匙从不丢失，遥控器也从不会滑进沙发缝里。但我们其他人呢——那些几秒钟前还在手边的东西，转眼就找不到的人。对于我们来说，蓝牙追踪器可以提供帮助。

Bluetooth trackers have been around for a long time, and they all generally work the same way. You attach the tracker to an object (a key ring, tote, in your wallet, etc), pair it with your phone, and then, if you lose said object, you can go into an app and ring the tracker. These days, Bluetooth trackers can do a lot more. Some have ultra-wideband chips that enable precision tracking, so you can find exactly where in a room your item is without having to sound an alarm. Most trackers tap into large networks — like Apple’s Find My and Google’s Find Hub — making it easier to locate lost items outside the home. Many will notify you if they detect you’ve left the device behind or come with QR codes that link to your contact information so people can easily return lost items. 蓝牙追踪器已经存在很长时间了，它们的工作原理基本相同。你将追踪器挂在物品上（钥匙扣、手提袋、钱包里等），与手机配对，然后如果丢了东西，就可以通过应用程序让追踪器发出响声。如今，蓝牙追踪器能做的远不止这些。有些配备了超宽带芯片，可以实现精准定位，让你无需鸣响警报就能找到物品在房间里的确切位置。大多数追踪器都接入了大型网络（如苹果的“查找”和谷歌的“查找设备”），这使得在户外寻找丢失物品变得更加容易。许多追踪器会在检测到你遗落设备时发出提醒，或者附带二维码链接到你的联系信息，以便他人能轻松归还丢失的物品。

These features are incredibly handy but also have the potential for misuse. For example, when Apple launched the AirTag, it seems the company hadn’t anticipated they might be used to track people or stolen items — but that’s exactly what happened. It’s since beefed up its anti-stalking features, and companies like Tile have also followed suit. Apple and Google have launched a standard that enables unwanted tracking alerts across both Android and iOS devices, and major players like Tile, Samsung, and Chipolo have supported the initiative. Still, it’s worth making yourself aware of each tracker’s approach to safety when deciding the best option for you. 这些功能非常实用，但也存在被滥用的可能。例如，当苹果推出 AirTag 时，该公司似乎没有预料到它们会被用来追踪他人或被盗物品——但事实恰恰如此。此后，苹果加强了防跟踪功能，Tile 等公司也纷纷效仿。苹果和谷歌推出了一项标准，支持在安卓和 iOS 设备上进行不必要的追踪提醒，Tile、三星和 Chipolo 等主要厂商也支持了这一倡议。不过，在决定选择哪款追踪器时，了解每款产品在安全方面的措施仍然很有必要。

As consummate Losers of Things, we have tested a fair share of Bluetooth trackers on wallets, keys, and luggage. Here’s what we’d recommend if you, too, have a hard time finding things. 作为资深的“丢三落四”人士，我们已经在钱包、钥匙和行李上测试了相当多的蓝牙追踪器。如果你也经常找不到东西，以下是我们推荐的产品。

The best tracker for iPhone users: Apple AirTag (second-gen)

苹果用户最佳选择：Apple AirTag（第二代）

If you’re an iPhone owner, Apple’s second-gen AirTag offers a level of precision that rival trackers simply cannot match. The updated model leverages the company’s latest ultra wideband (UWB) chip for its nifty Precision Finding feature, which, in turn, can lead you to your lost item with an on-screen arrow in the Find My app. Plus, because AirTags can tap into Apple’s vast Find My network, a lost tracker can anonymously ping its location to Apple’s iCloud servers whenever it’s near another Apple device, extending its range beyond Bluetooth’s limitations. 如果你是 iPhone 用户，苹果的第二代 AirTag 提供了竞争对手无法比拟的精准度。这款升级版机型利用了苹果最新的超宽带（UWB）芯片来实现其巧妙的“精确查找”功能，通过“查找”应用中的屏幕箭头引导你找到丢失的物品。此外，由于 AirTag 可以接入苹果庞大的“查找”网络，当丢失的追踪器靠近任何其他苹果设备时，它都能匿名将其位置发送到苹果的 iCloud 服务器，从而突破蓝牙的距离限制。

The best tracker for Android users: Tile Pro

安卓用户最佳选择：Tile Pro

More trackers these days offer support for both Google’s and Apple’s Find My networks, but Tile’s trackers remain our top recommendation for both Android users and those in mixed iOS / Android households. What’s more, Tile currently offers four form factors to suit different needs: the card-shaped Tile Slim, the square-ish Tile, the self-adhesive Tile Sticker, and the Tile Pro. The keyfob-shaped Tile Pro is our personal favorite; it’s larger than the Tile, offers the longest Bluetooth range at 500 feet, and has the loudest ring. Of the four, it’s also the only one that has a replaceable one-year CR2032 battery. 如今，越来越多的追踪器开始同时支持谷歌和苹果的“查找”网络，但 Tile 的追踪器仍然是我们对安卓用户以及 iOS/安卓混合家庭的首要推荐。此外，Tile 目前提供四种外形以满足不同需求：卡片式的 Tile Slim、方形的 Tile、自粘式的 Tile Sticker 以及 Tile Pro。钥匙扣形状的 Tile Pro 是我们的最爱；它比普通 Tile 更大，拥有 500 英尺的最长蓝牙连接范围，且铃声最响。在这四款产品中，它也是唯一一款配备可更换一年期 CR2032 电池的型号。
