What is the Health app on iPhone?
The Health app brings together all measurements of body values, sports and fitness data and apps in one clear list. Previously, each app collected this data separately, so it was difficult to get a complete picture of your health situation. It also made it more difficult to compare data.
The Health app contains data about your sleeping behavior, movement, heart rate and much more. This way you can see at a glance whether there is a connection between certain changes. Through Apple's health platform HealthKit, developers can ensure that their apps and accessories can write data to the Health app. For example, a connected scale can automatically save your weight in the Health app, so that other apps can read it again. You give permission for this per app, so that your privacy is not compromised. The Health app is only available on the iPhone, not on the Apple Watch, iPad or Mac.
The Health app first appeared in iOS 8 on the iPhone.
The app has three tabs at the bottom of the screen:
- Overview
- Share
- Data
You will spend most of your time in the Data tab. Here you can also indicate which apps are allowed to read data. If you set certain dates as favorites, they will appear on the Overview tab.
Set up and view health data
As indicated above, you decide which data you want to see on the Overview screen. You set this up via Details.
This is how you add a favorite to the Overview screen:
- Go to the Details tab.
- Choose a category, for example Mobility.
- Choose the measurement you want to mark as favourite, for example Cardio Fitness.
- Scroll down and add an asterisk to Add to favourites.
If you cannot find a particular measurement, use the search function on the Data tab. The first letters are enough. For example, enter ‘Sat’ to search for Saturation.
If you want to add a manual measurement, you can do that too:
- Go to the desired data, for example Saturation.
- Tap Add data .
- Enter the data manually and press Add.
Health app resources
The Health app reads all kinds of data of HealthKit-enabled apps and accessories. How do you know where all that data comes from? Very simple: by viewing the data sources:
- Go to the desired data, for example Saturation.
- Scroll down and tap Data sources and access.
- You will now see which apps you have given access for read and write. You can also see which devices performed the measurement. Multiple Apple Watch generations can be listed here.
- Tap a device or app to see the readings provided by this source.
