Why doesn't the tablet have Apple's own health software?

The health application on Apple's mobile phone comes with the system and cannot be downloaded by itself.

Because the health application uses the sensor of the mobile phone to track the amount of exercise, only the mobile phone is suitable;

For the iPad, there will be no health application software because it is inconvenient to carry.

Of course, if you want, you can also download some third-party health applications on the iPad.
