最佳健身追蹤器，誠實比較

For most people on an iPhone who want one device that does everything, the Apple Watch is the safest all-round pick. But "best" really depends on the job: Oura and Whoop lead on sleep and recovery, Garmin leads for serious endurance training, and Fitbit is the best simple, long-battery, cross-platform tracker. Match the device to your main goal rather than chasing a single winner.

Among full-featured options, Oura, Whoop, and Garmin all go for days to weeks between charges, while a standard smartwatch like the Apple Watch is typically a daily charge. If wearing it overnight without thinking about charging is your priority, a ring or band or a Garmin watch will suit you better than a flagship smartwatch.

It varies. Apple Watch and Garmin keep their core health features free on the device. Fitbit puts some deeper insights behind Fitbit Premium. Oura and Whoop are subscription-based by design, with Whoop bundling the hardware into the membership. Before you buy, separate the one-time hardware cost from the ongoing cost, because the cheapest device is not always the cheapest over a year.

For steps, heart rate, and sleep, the leading devices are all good and the differences are modest for everyday use. Wrist optical heart rate can lag during very intense intervals on any brand, and sleep-stage estimates are approximations everywhere. Accuracy matters less than consistency: a device you wear every day, read in context, beats a marginally more accurate one that sits in a drawer.

Yes. Wellness Project connects to Fitbit and Oura directly, reads Apple Watch data through Apple Health, and reads Garmin and Whoop data through Apple Health or Android Health Connect where those apps share it. Whatever you buy, the goal is the same: get its data into one record where an AI coach reads it alongside your training, nutrition, and recovery.
