Wearables and connected health devices translate measurements into information. Their usefulness depends on what is measured, how it is interpreted and whether the result answers your question. A fitness trend, a wellness estimate and a clinical measurement are different kinds of evidence.

Choose a wearable around one question you want answered
Use a measurement diary to evaluate useful records, wear time, exports and subscriptions before comparing wearable feature counts.
Bring these details
