The Fitbit Air is a good wearable weighed down by a chatty AI “coach”

Fitbit Air：一款被话痨 AI “教练”拖累的优秀可穿戴设备

Smartwatches can track your health stats, but they also do a lot of other things you might not always want or need. The $100 Fitbit Air tracker ditches the screens that have become common on people’s wrists, leaving behind a tiny puck of health sensors you can often forget you’re wearing. You will not, however, forget that Google’s new health platform is built around AI.

智能手表可以追踪你的健康数据，但它们也做了许多你未必想要或需要的功能。售价 100 美元的 Fitbit Air 追踪器摒弃了人们手腕上常见的屏幕，只留下一个微小的健康传感器圆盘，让你经常会忘记它的存在。然而，你绝不会忘记 Google 的新健康平台是围绕 AI 构建的。

The Air has no speaker, and there’s only one LED on the side to indicate battery level. You can double-tap the tracker to check the level, and that’s about the end of on-device features. The vibration motor is only for alarms—it can’t sync with notifications on your phone. That makes sense, given there is no screen to tell you what that buzz was all about.

Air 没有扬声器，侧面只有一个 LED 灯用于指示电量。你可以双击追踪器来查看电量，设备本身的功能仅限于此。振动马达仅用于闹钟——它无法与手机上的通知同步。考虑到没有屏幕来显示振动的原因，这一点倒也合理。

The stock Performance Band is simple, consisting of a smooth polyester yarn with small velcro pads and a metal loop. It’s durable but does seem to absorb a bit of moisture. For swimming or heavy workouts, you’ll probably want the silicone active band. This one hides the Air puck a bit more effectively, and it looks good in a sporty way. While $35 for a bit of silicone is rather spendy, that’s nothing compared to the $50 Elevated band, which is a more understated polyurethane option. However, it doesn’t make sense to pay half the cost of the tracker just for a band that looks marginally better.

原装的 Performance Band 设计简洁，由光滑的聚酯纤维纱线、小型魔术贴垫和金属环组成。它很耐用，但似乎会吸收一些水分。如果是游泳或高强度运动，你可能需要硅胶材质的 Active Band。这款表带能更有效地隐藏 Air 圆盘，且外观更具运动感。虽然 35 美元买一块硅胶表带有些昂贵，但这与 50 美元的 Elevated 表带相比还算便宜，后者是一种更低调的聚氨酯材质选项。不过，为了一个外观稍好一点的表带而支付相当于追踪器一半的价格，实在没有意义。

Third-party bands for the Pixel Watches have been mediocre and rare despite Google’s Apple-like commitment to its proprietary connector over the past four generations. The Fitbit Air is much simpler. The device just has to snap into a loop or frame to stay put. I’m hopeful that more band options will become available in the future because Google’s options are far too expensive.

尽管 Google 在过去四代产品中坚持使用类似苹果的专有连接器，但 Pixel Watch 的第三方表带一直稀少且平庸。Fitbit Air 则简单得多，设备只需卡入环扣或框架中即可固定。我希望未来能有更多的表带选择，因为 Google 官方的选项实在太贵了。

Unlike the simplistic fitness trackers of the past, the Fitbit Air has most of the sensors you’d find in a high-end smartwatch. It tracks your steps (obviously), heart rate, blood oxygen, and skin temperature—no ECG, though. These stats and their history are available in the app, but they also feed into various secondary metrics and evaluations like your “readiness score” and sleep phases.

与过去简单的健身追踪器不同，Fitbit Air 拥有高端智能手表中的大部分传感器。它能追踪步数（显而易见）、心率、血氧和皮肤温度——不过没有心电图（ECG）功能。这些数据及其历史记录可在应用程序中查看，它们还会被整合进各种次级指标和评估中，例如你的“准备度评分”和睡眠阶段。

There’s not really anything else to say about the device itself—the minimalism is one of its main selling points. You’ll barely notice the Air on your wrist, so it’s easy to wear all the time, and I can confirm it lasts a full week on a charge. Even fussy sleepers should have no problem wearing the Fitbit Air all night. The Air also uses its array of sensors to detect workouts, and it logs everything in the new Google Health app. Unfortunately, fitness buffs may find themselves too dependent on the app. You’ll have to go to the app for live stats during a workout because there’s no screen on the Air.

关于设备本身其实没什么可说的——极简主义是其主要卖点之一。你几乎感觉不到手腕上的 Air，因此它非常适合全天佩戴，我可以确认它充一次电可以使用整整一周。即使是睡眠挑剔的人，整晚佩戴 Fitbit Air 也不会有任何问题。Air 还利用其传感器阵列来检测锻炼情况，并将所有数据记录在新的 Google Health 应用中。遗憾的是，健身爱好者可能会发现自己过于依赖该应用。由于 Air 上没有屏幕，你在锻炼时必须查看应用才能获取实时数据。

The revamped app is decent and has most of the features you’d expect. If you’re a new user or someone who doesn’t spend much time nerding out over Fitbit data, you’ll probably be happy with the data logging and features. For long-time Fitbit users, the loss of features like blood pressure tracking or custom meal creation will be irksome. It’s also missing some basic layout customization options. Google says updates are on the way to address some of these concerns, though.

改版后的应用表现尚可，具备了你所期望的大部分功能。如果你是新用户，或者是不太钻研 Fitbit 数据的人，你可能会对数据记录和功能感到满意。但对于长期使用 Fitbit 的用户来说，血压追踪或自定义膳食创建等功能的缺失会令人恼火。它还缺少一些基本的布局自定义选项。不过，Google 表示更新即将推出，以解决其中一些问题。

The quality of data seems good to me, a mostly casual Fitbit user. Sleep tracking accurately detects my perceived timing, and the smart alarm works great. The readiness score often is a reliable predictor of how “good” I felt on a given day, too. I’ve been skeptical of the extreme datafication of health enabled by wearables, but Google does seem to be making progress.

对于我这样一个大部分时间只是随便用用的 Fitbit 用户来说，数据质量看起来不错。睡眠追踪能准确检测到我的入睡时间，智能闹钟也非常好用。准备度评分通常也能可靠地预测我当天的状态“好坏”。我一直对可穿戴设备带来的极端健康数据化持怀疑态度，但 Google 似乎确实在取得进展。

Your friend the coach

你的教练朋友

The Fitbit Air is a good fitness tracker, but Google’s new health AI has ramifications beyond this one wearable. If you’re a premium user, Google Health (which replaces Fitbit) includes the AI-powered Health Coach, and you won’t forget it’s available. The Air comes with three months of Premium, so this is the default experience. This AI model is woven through the app, presenting you with summaries, suggestions, and words of affirmation, whether you want them or not.

Fitbit Air 是一款不错的健身追踪器，但 Google 的新健康 AI 的影响远不止于这一款可穿戴设备。如果你是高级会员，Google Health（取代了 Fitbit 应用）将包含 AI 驱动的“健康教练”，而且你绝不会忘记它的存在。Air 附赠三个月的高级会员资格，因此这是默认体验。这个 AI 模型贯穿于整个应用中，无论你是否需要，它都会向你提供总结、建议和鼓励的话语。

In some ways, Health Coach is a good application for generative AI. The Gemini-based model running the show is not a generalist—it was tuned specifically for this one task, and it’s grounded by the data your wearable collects. The Coach offers basic rundowns of your health and physical activities based on the metrics it tracks. But no amount of health-focused tuning will change the fundamental issues with generative AI. I’ve encountered a few minor hallucinations, mostly related to inventing workouts that didn’t happen.

在某些方面，“健康教练”是生成式 AI 的一个良好应用场景。运行该功能的 Gemini 模型并非通用型 AI——它是专门针对这一任务进行调优的，并以你的可穿戴设备收集的数据为基础。教练会根据它追踪的指标提供你健康和身体活动的简要总结。但无论进行多少针对健康的调优，都无法改变生成式 AI 的根本问题。我遇到过几次轻微的“幻觉”现象，主要是虚构了一些我并没有进行的锻炼。
