Viewing Health and Sensor Info

*Sideload version only.* Open Heart Rate from Programs - its screen is titled Heart rate check. The reading starts on its own the moment you open the screen, which is also when the watch asks for heart-rate access, and keeps updating until you leave the screen or it goes dark; a Measure button is there too, in case you want to nudge a fresh reading without leaving and reopening the screen. Readings save once a minute as they come in, so a few minutes of wear leaves a row of values instead of a single number, and a trend chart of the recent readings appears directly under the current figure once there are two or more.

Cannot get a reading? The screen says exactly why instead of leaving you looking at a blank one: no heart-rate sensor on this watch, access not granted, the watch is not being worn, the Wear OS version is too old for the health service, or the measurement timed out or failed.

History keeps every past measurement with its time, up to the newest five hundred. From there, History & Analytics adds the average, lowest and highest reading and which zone your latest one falls in - Low, Normal, Elevated, Cardio, Peak or Max, with 60-100 bpm named as the normal resting range.

*Sideload version only.* Open Blood Pressure from Programs. Keep the arm still at heart level and tap Record pulse wave - the watch records a 30-second pulse wave from its optical sensor and turns it into a systolic and diastolic estimate, always labelled Estimate together with how many calibrations it rests on, how old the newest one is, and the model's margin of error.

The estimate needs calibrating first: open Calibration, start a real blood-pressure cuff on the other arm, and type in what the cuff reads while the watch records alongside it - each pair of cuff numbers and watch pulse is saved as one calibration, and the more you add, the tighter the estimate gets. A cuff reading typed in earlier versions of this screen now feeds a calibration rather than being kept as its own tracked value.

A reading can also be refused, always with its own reason: no permission granted, the watch off the wrist, the wrist moved during the 30 seconds, too weak a pulse signal, or too few calibrations recorded yet. History & Analytics adds the average, lowest and highest estimate and which category the latest one falls in - Low, Normal, Elevated, Stage 1, Stage 2 or Crisis, with 120/80 mmHg named as normal.

Open Activity & Motion from Programs to see what the watch's movement sensors are reporting right now. The Motion group covers the accelerometer, gyroscope and rotation vector, each with its live reading, how many events have arrived, the delivery rate, and how long ago the last one came in - a sensor that stopped answering shows a growing age instead of looking exactly like a healthy one. A sensor this watch does not have says so, rather than sitting at zero, which is itself a real measurement. Every subscription stops the moment you leave the screen.

*Sideload version only:* the Activity group adds the step counter and step detector, asking for activity access only when you open that group rather than at startup. On the Google Play build, or if access is declined, the group names which of three reasons applies instead of showing a step count of zero: no such sensor, access declined, or not carried by this edition.

System information's Environment section - see wrist programs and tools for the rest of that screen - shows live readings from the light, pressure and magnetic-field sensors, and states plainly for each one whether it answered, answered but is not to be trusted, stayed silent, or simply is not fitted to this watch.
