Why not use Apple's own health software?

Hello, I'm glad to answer your question. Ios8' s health needs to be integrated with other software to provide data for use. Then all these other softwares have to be downloaded from American servers. We need instruments to test it. But don't worry, some data can still be filled in, such as creating a medical card and basic data. Then this health software only comes with ios8 system. It was put on the shelves before, and it was taken off the shelves in a few days.
