How can I record my weight using Siri? I want to use Siri to record my weight in Apple’s Health app. However, when I tell Siri “Record my weight as X pounds”, she responds “I can’t answer that on your iPhone, but you can find it in the Health app”.

Is it possible to record my weight in Apple’s Health app using Siri?
It's not directly possible to say "Hey Siri. Record my weight as X pounds" currently (up to and including iOS 12).

However, there are two ways you can do this(-ish).


Siri Suggestions: if you launch the Health App (manually) and log your weight enough times, it will start showing up as a Siri Suggestion in Search. This will launch the Health App in the Weight section, and you can then log your weight manually.
Shortcuts: you can create a shortcut in the Shortcuts App. Use the Log Health Sample action, and select Body Measurements --> Weight. This will allow you to manually log your weight from a prompt. You can have it triggered by saying "Hey Siri. Record my weight". If you want you can make this more sophisticated with a combination of alerts/prompts and variables. It is not possible to launch a Shortcut and pass it input in the same statement (i.e. "Record my weight as X pounds", but you can launch the shortcut, and then have the shortcut use voice prompts and take voice input from you (note, you will have to convert text input to a number for the Health App). You will very quickly come to realise that Shortcuts is not a programming language, and gets clunky very fast. It's ugly (and fragile!), but it works (except when it doesn't)
