8 parts, in order. A new one goes up every morning at 11:30, so this list grows until the series is complete.
- What a Fitness Band Can and Cannot MeasureThe tiny sensors under the strap, and the honest line between what a band measures and what it is quietly estimating.
- Band or Smartwatch? How to Decide Before You BuyJudge a wrist device by how you will actually wear it, not by the feature list printed on the box.
- The First Hour With a New Fitness Band or WatchPairing, profile details, wrist choice and strap tightness decide whether every number you see for the next year makes sense.
- Why Your Step Count Never Matches Your Friend'sOne walk, two devices, two different numbers, and why chasing a round daily target misses the point entirely.
- What Your Watch Is Doing When It Reads Your PulseA green light on your skin reads a pulse well when you are still and badly when you are working hard.
- Reading a Sleep Score Without Losing Sleep Over ItYour watch infers sleep from movement and pulse, so treat the score as a rough diary rather than a verdict.
- SpO2 and ECG on a Watch: What They Are NotTwo wrist features that borrow medical names, what each one actually checks, and why an odd reading is a prompt to ask a doctor.
- Your Watch Buzzes Twice: Fixing Wrist NotificationsA watch either halves your phone checking or doubles it, and the difference is deciding which alerts earn your wrist.
