"A cheap Bluetooth remote for your phone that masquerades as a health device."
'Comprehensive Health Monitoring' translates to watch faces that display numbers for heart rate and blood oxygen. The hardware cost makes it impossible for these numbers to be consistently accurate, so they exist primarily for marketing bullet points.
This is for a buyer who wants the aesthetic of a smartwatch and basic on-wrist call/text notifications for the lowest possible price. The user must understand that the health tracking features are for novelty purposes only and not to be trusted for actual fitness or medical insight.
Anyone intending to seriously track exercise, monitor a health condition, or who expects a durable, long-lasting device should skip this. Investing in an entry-level device from a reputable brand (Fitbit, Amazfit, Garmin) provides validated sensors and a supported software ecosystem for a modest price increase.
