Record weight and oxygen saturation
On the Data tab, tap the plus next to Weight or Oxygen saturation, set the value on the slider and tap Add. Both are saved with the blood pressure reading. Choose kg or lbs once by tapping the unit.
You can record your weight and your blood oxygen saturation (SpO2) together with a blood pressure reading. Both are optional and free. Measure them with your own scale and pulse oximeter; the app only records the values.
Add your weight
-
Open the Data tab and set your blood pressure values as usual.
-
Scroll down to Weight and tap the plus icon.
-
Swipe the slider to your weight, or tap the number and type it. You can enter one decimal, for example 72.5.
-
Check the unit next to the slider. To change it, tap it; see "Kilograms or pounds" below.
-
Tap Add.
The slider starts at the last weight you recorded. To remove the weight from this reading before you save, tap the icon next to Weight again.
Add the weight every time
If you weigh yourself whenever you measure your blood pressure, switch on Always add weight. The weight section then stays open after each save.
Kilograms or pounds
The unit is shown in brackets next to the weight slider. Before you choose, it shows Unit. Tap it to switch between kg and lbs. The choice applies to the whole app.
The app does not convert values. If you switch the unit, the numbers you recorded earlier stay as they are and are shown with the new unit. Choose the unit once, before your first weight, and keep it.
Add oxygen saturation
-
On the Data tab, scroll down to Oxygen saturation and tap the plus icon.
-
Swipe the slider to the value from your pulse oximeter, or tap the number and type it. The slider goes from 80 to 100 percent and starts at your last value.
-
Tap Add.
Oxygen saturation is not kept open: you add it again for each reading.
Where you see the values
Weight and oxygen saturation are saved in the same record as the blood pressure reading. You see both in the details of the reading, under Health Metrics in the analysis, and in the PDF report. The weight is also drawn in the chart; oxygen saturation is not. See See the details of a reading and Follow your readings on a chart.
To add a weight to a reading you already saved, or to remove one, see Edit or delete a reading.
What to check if it does not work
- The unit shows Unit. You have not chosen one yet. Tap it once to choose kg, twice for lbs.
- Your earlier weights look wrong after changing the unit. The app shows the old numbers with the new unit. Tap the unit again to switch back.
- A weight appears on every reading. Always add weight is switched on. Open the weight section and switch it off.
