For the General Health app, it is possible to add your data manually for a variety of metrics. These include: blood pressure, weight and food data. For Android: Select the pencil visible in the bubble and follow the steps. For iOS make sure manual tracking is switched on, by tapping the wheel and selecting Manual tracking. You can then manually indicate whether you would like to track blood pressure, weight, or nutrition. These options will already be switched on if you have a Philips health watch paired to your app. For manually adding data tap the + and follow the steps to add your data. Please note that it is not possible to manually add activity or sleep data.
