健康穿戴设备该买哪一款?

如果你在意的是睡眠和恢复,买智能戒指——这是大多数人愿意整夜戴着的唯一形态。如果你需要内置 GPS 和心电图,买运动手表。想完全避开订阅,可选清单是 Polar、Garmin、三星、Ultrahuman 和 Withings;Whoop 根本不单卖设备,只随年度会员提供,而 Oura 的 Gen3 及更新款戒指必须订阅 Membership。下面是 12 款在售设备,每一项参数都追溯到厂商自己的页面,并标注核实日期。

最近核实 2026-08-0612 款设备 · 每款 30 项参数 · 69 个单元格厂商未公布任何数值
六个问题。给出一个主推和两个备选,只依据上方经核实的参数评分。

整页贯穿一条规则:厂商没有公布的数字,单元格就写「Not stated」(未说明)。这里没有任何估算、没有从相近型号推断、也没有从评测里抄。一张明显不完整的表格是诚实的;一张自信而错误的表格会被引用并扩散开来。空白单元格本身就是发现:好几家厂商至今不公布重量,还有几家从来没有提到过一项本该属于该品类的指标。

三种被反复混为一谈的说法

设备能测App 会显示API 会开放,是三件不同的事。一台设备可以带血氧传感器,却只在你主动要求时测一次:Polar 自己的手册写着 Vantage V3 测血氧「whenever you want in just 45 seconds」,而 Oura 明确说只在睡眠期间测。Garmin 则让你自己选:全天、睡眠期间,或手动。设备也可能算出一项指标,却把它藏在最便宜的套餐之外:Whoop 的血氧、皮肤温度和呼吸频率都在 Health Monitor 里,而 WHOOP One 会员拿不到这个功能。下面的表格把这些分开:「设备测什么」讲的是硬件以及厂商声称它产出什么,「数据获取」讲的是什么能离开设备。

形态与实用性

续航数字是厂商标称,不是实测结果。真实续航取决于你让传感器干多少活。

Sampling cadence not statedContinuous — 24/7 heart rate tracking, with high and low heart-rate notificationsContinuous — enhanced PPG sensor, always-on trackingContinuous — always-on trackingContinuous — wrist-based heart rate, 24/7 health monitoringContinuous — wrist-based Garmin Elevate optical heart rateContinuous — third-generation optical heart sensor, plus an electrical heart sensorYes — optical bio-signal sensor. Samsung's page does not state a sampling cadenceContinuous — 24/7 heart rate
HRV
以及何时采样
Overnight only. Oura states it measures HRV only during sleep, in five-minute samples through the night, and shows the mean of those samplesNightly — HRV is measured during sleepNightly — Nightly Recharge is an overnight measurementYes. Sampling window not statedOvernight — Withings describes overnight heart rate variability trackingOvernight. Whoop states HRV is "passively tracked throughout sleep", and takes the nightly reading that drives Recovery during slow-wave sleepOvernight — "passively tracked throughout sleep", with the Recovery reading taken during slow-wave sleepYes — HRV is part of the overnight sleep breakdownOvernight. Garmin measures the time between heartbeats while you sleep, and needs 7 nights before showing a 7-day average and about three weeks before comparing it to your baselineSampled through the day rather than overnight. Apple's own heart-rate paper describes a background algorithm that monitors heart rate all day but reports readings when the wearer is still, attempting one reading every 5 minutes, and computing HRV as SDNNNot statedYes. Sampling window not stated
静息心率Yes — Resting Heart Rate is one of the nine Readiness Contributors. Oura "evaluates the lowest heart rate from the previous night against the long-term average heart rate"Not statedNot statedYes — resting heart rateNot statedYes — Resting Heart Rate is a Health Monitor metric and is in the exported Physiological Cycles CSVYes — a Health Monitor metric, included in the CSV exportNot statedNot statedNot statedNot statedYes — resting heart rate
血氧
整夜还是点测
Yes, overnight. Oura states SpO2 is measured "while you sleep", needs a sleep period longer than three hours, and reports Average Blood Oxygen as a percentage for the longest sleep of the day. Gen3 or later with an active Membership only — not available on Gen2 or olderNo SpO2 sensorOn demand only. Polar's user manual: "You can measure SpO2 conveniently from your wrist whenever you want in just 45 seconds." Polar also states the feature "is not intended for any medical use, diagnosis, or treatment"Not stated for the Ring PRO. The sensor list is a temperature sensor, a PPG heart-rate sensor and a 6-axis IMU. Ultrahuman's Ring PRO product page, its buy page, its ring FAQ and the field list for its Partner API contain no mention of SpO2, blood oxygen or pulse oximetryYes — blood oxygen. Withings states plainly that "SpO2 measurement is a wellness feature and therefore not clinically validated". Overnight-versus-spot behaviour is not statedYes. Whoop's export documentation lists SpO2 for "WHOOP 4.0+", and Blood Oxygen is a Health Monitor metric. ⚠️ Health Monitor is available to WHOOP Peak and WHOOP Life members only — Whoop states WHOOP One members do not have accessYes — Blood Oxygen is a Health Monitor metric and is exported for WHOOP 4.0+. MG ships on the Life membership, which includes Health MonitorPulse Ox, with the mode chosen by the user: "All Day" takes measurements while you are inactive during the day, "During Sleep" turns on continuous measurements while you sleep, and readings can also be started manuallyPulse Ox, with the mode chosen by the user: "All Day" measures while you are inactive during the day (Garmin notes this decreases battery life), "During Sleep" takes continuous measurements while you sleep, and a reading can be started manually. Garmin notes regional availability limitsBlood oxygen sensor presentYes, during sleep. Samsung states the ring "can track your sleep patterns by measuring your heart rate, blood oxygen, and skin temperature while you’re sleeping", and that blood oxygen is an option you enable in sleep tracking. Whether the reading is continuous through the night is not statedYes — SpO2. Overnight-versus-spot behaviour not stated

No GPS in the ring. Sensors listed are LEDs, photodetectors, a temperature sensor and an accelerometerNo GPS. Sensors are optical heart rate and an accelerometerBuilt-in dual-frequency L1/L5 GNSS: GPS, GLONASS, Galileo, BeiDou, QZSS. 150+ sport profilesNo GPS. Sensors are temperature, PPG and a 6-axis IMUConnected GPS only. Withings answers "Does ScanWatch 2 have a built-in GPS? No." — it needs a Bluetooth connection to your phone for distance-based outdoor activitiesNo built-in GPS. Whoop pulls GPS, distance, pace, power and cadence from Strava activities insteadNo built-in GPS; GPS data comes in from StravaConnected GPS only — outdoor tracking requires pairing with a compatible iPhone or Android phoneBuilt-in multi-band GPS with SatIQBuilt-in — L1 GPS, GLONASS, Galileo, QZSS and BeiDouNo GPS in the ringNo GPS listed. Google’s announcement, its getting-started help article and its tech-specs page all describe tracking without naming GPS, built-in or connected
心电图 / 房颤
以及监管状态
No ECG. Oura's Ring 5 specification lists no electrical heart sensorNo ECGWrist-ECG sensor present (Elixir GEN 1), taken on demand in about 30 seconds by resting a finger on the button. Polar's pages describe ECG readings but name no regulatory clearance and no cleared regionsNo ECG — no electrical heart sensor is listed. There is AFib detection: Ultrahuman states its AFib Detection PowerPlug "discreetly monitors your heart rhythm every night to detect signs of Atrial Fibrillation". It is a paid add-on, bundled with Cardio Adaptability at $2.9/month, and Ultrahuman describes "medical approval in limited markets currently" — available in Europe, the UK, Turkey and Switzerland, with the USA, UAE and India listed as coming. No specific clearance or CE marking is namedYes — electrocardiogram. Withings calls it "a medical-grade ECG" on the product page and describes the ECG monitor as clinically validated in its FAQ, but names no specific clearance and no covered regions. Withings warns it is not suitable for people with a pacemaker, whose electrical signals may induce wrong ECG measurementsNo. Whoop states plainly that WHOOP 5.0 'does not include ECG or Blood Pressure Insights'Yes — ECG and Heart Screener, exclusive to MG on the Life membership, plus Irregular Heart Rhythm Notifications. Whoop calls both 'medically regulated' and says they are not available in every region; within the EU/UK they are unavailable in the Faroe Islands, Guernsey, Isle of Man, Jersey, Monaco and Greenland. Not intended for under-22s, for people with known arrhythmias other than AFib, or for people with pacemakers or ICDsNo ECGYes — the Garmin ECG App records an ECG similar to a Lead I ECG and can detect atrial fibrillation or normal sinus rhythm. Garmin states it is only available on select watches, is not available in all regions, and is only intended for adults aged 22 and overYes — ECG app plus irregular rhythm detection.

有公开 API 吗?Yes, public. Anyone with an Oura account can create an application in Oura's developer portal. Gen3-and-later users need an active Membership for API accessYes — Polar Open AccessLink. A free Polar Flow account is enough to register as a third-party developer; no device requiredYes — Polar Open AccessLink, free developer registrationPartner API, not open self-serve. Approved apps read user-consented data over OAuth 2.0, and the user must generate a data-sharing code in the Ultrahuman appYes — Withings runs a Public API described as 'designed for individuals and partners without a formal contract'Yes — Whoop runs a developer platform exposing recovery, sleep, strain, workouts and cycles, with an app approval stepYes — same Whoop developer platformNot self-serve. The Garmin Health API requires approval before you reach even an evaluation environment, and Garmin states commercial use requires a licence feeNot self-serve. Garmin Health API access requires approval, and Garmin states commercial use requires a licence feeNo server-side API. Apple states that Health data you choose to share is provided directly to the app on the device and Apple does not get access; the data sits in a Data Protection class whose access is relinquished 10 minutes after the device locksNo public cloud API. Samsung's route is the Samsung Health Data SDK, an Android on-device SDK; writing data or distributing an app requires an approved Samsung partnershipYes, but under review. The Google Health API replaces the Fitbit Web API, and Google states all its scopes are Restricted, requiring a privacy and security review for access
能自行导出吗?Yes — data files can be downloaded from the Membership Hub, including by users without an active MembershipNot statedNot statedA personal API token can be created from Ultrahuman's developer portalNot statedYes — CSV export from the app, on every membership tier.

Oura Readiness、Whoop Recovery、Polar Nightly Recharge、Garmin Body Battery 和三星 Energy Score 是不同刻度上的不同构造,用不同的输入、在不同的时间点采样得来。一家的 70 分不等于另一家的 70 分,跨设备取平均得到的数字毫无意义。Garmin 明确写道,Body Battery 由心率变异性、压力水平、睡眠质量和活动数据构成,刻度为 5 到 100,并且会随着白天推移而变化——是一个实时油量表。Whoop 的 Recovery 则锚定在深睡期采得的单次夜间 HRV 读数上。这两者回答的是不同的问题。每个评分只应与它自己的历史比较。

HRV 采样时机这一列最能说明问题。Oura 只在睡眠期间采样。Whoop 在慢波睡眠期间取值。Garmin 在你睡觉时测量心跳间隔,需要七个夜晚才会给出七日均值。Apple Watch 做的则完全是另一件事:苹果自己发布的心率文档描述了一个后台算法,全天监测心率,并在你静止时大约每五分钟报告一次,以 SDNN 表示。四台设备,四种不同的「你的 HRV」。

最适合……

最适合睡眠
智能戒指,因为这是你真正会整夜戴着的形态。Oura Ring 5 最轻 2 克,Oura 声明只在睡眠期间采样 HRV,按五分钟一段取值再求平均。Ultrahuman Ring PRO 重 3.3–4.8 克,标称最长 15 天续航,所以很少需要在睡前摘下来充电。
最适合训练
带内置 GPS 的运动手表。Polar Vantage V3 配备 L1/L5 双频 GNSS,标称 43 小时 GPS 训练时长;Garmin Venu 4 配备多频 GPS,并加上 Body Battery、HRV Status 和心电图应用。Whoop 和本次对比中的任何一款戒指都没有自带 GPS。
最适合不想订阅
Garmin CIRQA Smart Band,199.99 美元。Garmin 自己的宣传语就是「Track all day. Look later. No subscription required.」,并说明数据同步到 Garmin Connect 不额外收费。Polar 也做出同样的书面承诺:「No monthly fees. No locked features. Full access to every feature from day one.」
续航最长
Withings ScanWatch 2,标称 35 天。其次是 Ultrahuman Ring PRO 最长 15 天,然后是 WHOOP 5.0 和 WHOOP MG 的 14 天以上。另一端,Apple Watch Series 11 标称正常使用最长 24 小时——每天一充,如果你想记录睡眠,这是个实实在在的限制。
最适合掌控自己的数据
Polar 和 Withings。Polar 的 Open AccessLink 只需一个免费的 Polar Flow 账号即可注册为开发者,无需持有设备;Withings 把自家公开 API 描述为面向没有正式合同的个人与合作伙伴。Oura 的 API 对任何 Oura 账号持有者开放,但 Gen3 及更新款戒指需要有效的 Membership。
最难把数据取出来的
Apple Watch,从 iPhone 以外的任何设备上都难。苹果声明你分享的健康数据直接交给设备上的 App,苹果自身不会获得访问权——不存在服务端 API。Garmin 的 Health API 需要审批,并且 Garmin 说明商业用途需要支付授权费。

最佳睡眠监测设备

睡眠监测设备的价值,取决于你愿不愿意戴着它睡觉,所以戒指在舒适度上占优:Oura Ring 5 最轻 2 克,Ultrahuman Ring PRO 3.3 克,而 Whoop 手环约 26.5 克,最小号 Apple Watch 30.3 克。续航同样重要,因为夜里要充电的设备就是会漏记夜晚的设备。Apple Watch Series 11 标称正常使用最长 24 小时;这里其他所有设备都标称一周以上,Withings ScanWatch 2 标称 35 天。

论夜间真正记录了什么,有四款突出。Oura 在睡眠期间测血氧,需要超过三小时的睡眠时段,并给出当晚的平均血氧。Withings 提供 24/7 体温追踪,外加夜间 HRV 和呼吸质量指数。Garmin 的 CIRQA 和 Venu 4 可以把 Pulse Ox 设为「During Sleep」,实现整夜连续测量。三星 Galaxy Ring 在你睡觉时测量心率、血氧和皮肤温度。Whoop 同样提供血氧、皮肤温度和呼吸频率——但仅限 Peak 和 Life 套餐,因为 Whoop 明确说明 WHOOP One 会员没有 Health Monitor。

最适合测 HRV 的穿戴设备

如果 HRV 是你在意的数字,问题不在于谁能测——这里几乎全都能测——而在于*什么时候*测。Oura 声明只在睡眠期间测量 HRV,整夜按五分钟一段采样,并显示这些样本的平均值。Whoop 在睡眠期间被动追踪 HRV,并在慢波睡眠期间取用于 Recovery 的那一次读数。Garmin 在你睡觉时测量心跳间隔,需要七个夜晚才显示七日均值,约三周后才会与你的基线对比。Polar 每晚为 Nightly Recharge 采集 HRV,Loop 和 Vantage V3 都是如此。

Apple Watch 是异类:苹果自己的心率文档描述了一个后台算法,全天监测心率,并在你静止时大约每五分钟报告一次,以 SDNN 发布。这是在不同时间采集的不同统计量,所以苹果的 HRV 数值不能拿来和夜间数值比较。三星则是空白——Galaxy Ring 的产品页、购买页和两篇支持文章里都没有提到 HRV。

若想把 HRV 从厂商 App 里取出来做自己的分析,Polar 和 Withings 最容易:两家都有可以直接注册的公开 API。Oura 的 API 对任何账号持有者开放,但 Gen3 及更新款戒指需要有效的 Membership。什么算是好的 HRV 是另一个问题——简短的答案是,它只有相对于你自己的基线才有意义。

每款设备在什么时候采集你的 HRV
同一个夜晚,六种不同答案。这就是同时佩戴两台设备会得到不一致结果的原因——它们不在同一时刻测量,其中一款甚至测的不是同一个统计量。

Oura 对比 Whoop

最清楚的差别是商业模式,不是技术。Oura 卖给你一只戒指——欧盟商店银色或黑色 429 欧元——然后对 Gen3 及更新款戒指每年收 69.99 欧元的 Membership,两年合计 568.98 欧元。Whoop 根本不单独卖设备:欧盟商店 WHOOP One 每年 199 欧元,WHOOP Peak 每年 264 欧元,各含一台 WHOOP 5.0,所以两年是 398 或 528 欧元,硬件已包含在内。技术上,戒指 2 克,手环约 26.5 克;两者都没有 GPS。想要心电图就得选每年 399 欧元 Life 套餐里的 WHOOP MG,因为 Whoop 直接写明 WHOOP 5.0 不带这项功能。另可参阅我们更长的一篇:恢复评分为何互不一致

智能戒指还是手表

这里的三款戒指——Oura Ring 5、三星 Galaxy Ring、Ultrahuman Ring PRO——都没有 GPS,也没有心电图。三款都标称一周以上续航,重量都在十克以内。手表则相反:Apple Watch Series 11 增加了心电图、跌倒检测、内置 GPS 和睡眠呼吸暂停提醒,但标称正常使用最长 24 小时,意味着你得围着睡眠时段安排充电。Withings ScanWatch 2 是个例外——一款带心电图和 24/7 体温追踪的混合指针表,标称 35 天。

无需订阅的穿戴设备

Garmin 在这点上说得最响。CIRQA Smart Band 的宣传语就是「Track all day. Look later. No subscription required.」,Garmin 并说明数据同步到 Garmin Connect App 不额外收费,Connect+(每月 6.99 美元或每年 69.99 美元)纯属可选。Polar 也白纸黑字写着:「No monthly fees. No locked features. Full access to every feature from day one.」另一个极端是 Whoop,完全没有免订阅的路径;而 Oura 的 Membership 正是 Gen3 及更新款戒指解锁 API 的钥匙——所以如果你打算在 Oura App 之外使用自己的数据,Membership 就不是可选项。

两年到底要花多少
硬件与强制订阅分开计算。Whoop 没有硬件条,因为 Whoop 不在会员之外单卖设备。可选项——Withings+、Ultrahuman 的付费 PowerPlug、Garmin Connect+、Google Health Premium——均未计入。

名词解释

HRV(心率变异性) 是相邻两次心跳间隔时间的波动,以毫秒计。它不是体能评分,而是对自主神经系统平衡的粗略读数,只有相对于你自己的基线才有意义。各家的算法不同——苹果发布的是 SDNN,即正常心跳间隔的标准差——采样时间也不同,这就是为什么同一晚戴两台设备会得到不一致的结果。

就绪度或恢复评分 是厂商把夜间信号(通常是 HRV、静息心率、睡眠和近期活动)按自家专有方式混合后压缩成的单一数字,一般是 0 到 100。行业内既无统一定义也无共用刻度。SpO2 是血氧饱和度,通过光学方式估算。皮肤温度 通常报告为相对你自己近几晚的偏差,而不是绝对值。连接式 GPS 意味着设备本身没有 GPS 芯片,借用手机的。

老实说,Vitra 处在什么位置

Vitra 是一款桌面应用,读取你戒指的数据并解释给你听。上面表格的最后一行只有三种状态。支持——Oura,通过公开的 Oura API 读取,这就是目前受支持的全部清单。开发中——Polar,代码已经写好,但仍在一个未打开的开关后面;此外还有 Ultrahuman 和 Withings,两者都在开发清单上,因为它们各自都有第三方真正能够到的 API。这三者目前都还不可用,也都没有对外提供。不支持——其余全部,单元格里写的是真实原因,而不是含糊的「即将推出」。凡是没有真正列入开发清单的,都不会被标为「开发中」。

其中两款设备根本无法被桌面应用支持,与其含糊带过,不如说清楚原因。Apple Health 把数据交给运行在用户自己 iPhone 或 Apple Watch 上的 App;苹果声明没有任何途径让苹果自身获得访问权,也不存在桌面应用可以调用的服务端 API。Samsung Health 通过 Android 端上 SDK 读取,没有公开的云端 API。谷歌的云端路径 Google Health API 把每一项权限都放在隐私与安全审核之后。这些都是可核查的事实,不是借口——但它们同样是 Mac 或 Windows 应用短期内不会读取你 Apple Watch 的原因。

不太光彩的部分:由于 Vitra 通过 Oura API 读取 Oura,而 Oura 对 Gen3 及更新款戒指的 API 访问要求有效的 Membership,Vitra 无法替你免掉这笔经常性支出。它免掉的是自己的那份——Vitra 是一次性买断——但底下那层 Membership 是 Oura 的,不是我们的。

常见问题

我该买哪一款穿戴设备?
取决于你想回答哪个问题。若要以最不打扰的形态记录夜间睡眠与恢复,Oura Ring 5 或 Ultrahuman Ring PRO 这类智能戒指最合适。若要带内置 GPS 的训练负荷记录,选 Polar Vantage V3 或 Garmin Venu 4 这类运动手表。若要完全避开订阅,Polar、Garmin、三星、Ultrahuman 和 Withings 出售的设备都没有强制性经常性费用,而 Whoop 只有订阅一种形式,Oura 则对 Gen3 及更新款戒指要求 Membership。
最好的睡眠监测设备是哪款?
除表格另有说明外,本次对比中的每款设备都会报告睡眠阶段,所以差别在于它们夜间还测了什么,以及戴着睡觉是否舒服。戒指最适合夜间佩戴;Oura Ring 5 整夜按五分钟一段采样 HRV,Withings ScanWatch 2 则在夜间 HRV 之外提供 24/7 体温追踪。
智能戒指比智能手表更好吗?
它们测的东西不一样。戒指更小,续航以天计而不是以一天计,戴着睡觉也舒服,但本次对比中的戒指都没有 GPS 和心电图。手表则增加了内置 GPS、多款机型上的心电图应用、Apple Watch 的跌倒检测和一块屏幕——代价是 Apple Watch 需要每天或近乎每天充电。
哪些穿戴设备不需要订阅?
Polar Loop、Polar Vantage V3、Garmin CIRQA、Garmin Venu 4、三星 Galaxy Ring、Ultrahuman Ring PRO 和 Withings ScanWatch 2 都不需要强制订阅。Garmin 为 CIRQA Smart Band 打出的宣传语是「Track all day. Look later. No subscription required.」有两款要加个星号:Ultrahuman 的房颤检测是每月 2.9 美元的付费 PowerPlug,Withings 的心内科医生心电图复核需要 Withings+。Whoop 与它们全都相反:设备只能随年度会员一起获得。
Oura Ring 需要订阅吗?
Gen3 及更新款需要。欧盟地区 Oura Membership 为每月 5.99 欧元或每年 69.99 欧元。Oura 说明,没有它戒指和 App 仍能运行,但可获得的洞察要有限得多——并且 Gen3 及更新款用户若没有有效 Membership,将完全无法通过 Oura API 访问自己的数据。Gen2 戒指不受此限制。
Oura 和 Whoop,测 HRV 哪个更好?
它们在不同时刻采样 HRV,这正是两者数值不一致的原因。Oura 声明只在睡眠期间测量 HRV,整夜按五分钟一段采样并显示平均值。Whoop 在慢波睡眠期间取夜间读数,用于其 Recovery 评分。这两个数值彼此不可比,也无法与 Apple Watch 的 SDNN 相比——后者是在白天你静止时采集的。
我能把自己的数据从这些设备里导出来吗?
差别很大。Oura、Polar 和 Withings 都有开发者可以直接注册的公开 API。Whoop 和 Ultrahuman 有带审批环节的开发者平台。Garmin 的 Health API 需要审批,并说明商业用途需要支付授权费。苹果完全没有服务端 API——健康数据是在设备上交给 App 的。Google Health API 的所有权限都属受限类别,需要经过隐私与安全审核。
这些穿戴设备中哪些能配合 Vitra 使用?
「Works with Vitra」这一行只有三种状态,没有中间地带。支持:Oura Ring,通过公开的 Oura API 读取。开发中:Polar,代码已写好但仍在未打开的开关后面,以及 Ultrahuman 和 Withings,两者都在开发清单上,因为各自都有可触达的 API。不支持:其余全部,每一项都给出真实原因——Apple Watch 是因为 Apple Health 没有桌面应用可调用的服务端 API;三星 Galaxy Ring 是因为 Samsung Health 是 Android 端上 SDK;Garmin 是因为其 Health API 需要审批和商业授权;Whoop 是因为没有在做任何集成。
