How does the health application of iphone import data from other applications?

1. After opening the health application, please click the "Health Data" column. 2. Next, we will see that the health application has multiple health classification categories. Take "Fitness Data" as an example. 3. Next, for example, I choose an option "calories burned in activities". Note: This option doesn't even support iPhone5s and iPhone6. I have to rely on other third-party applications or iPhone 6. You can see that there are data in the chart later, because I use the third-party application software. At this point, please click * * * to enjoy the data column. 5. Next, in the * * * enjoyment data list, under "data source", you can see the word human, which is an application software that can be downloaded for free in the AppStore. 6. When we click on it, we can check the detailed sports data recorded by it. 7. Therefore, we can also use third-party applications to monitor the iPhone4s. No matter what third-party health application software you use, remember to turn on "Show in Chart Summary" after accessing the health application. 8. In this way, we can view all the health data we want in the column of "Chart Summary".
