I had to delete my Health apps, and their databases, to solve a data sync problem across devices. So I exported my data and bought the Health Importer bundle to restore data to my iPhone (XS; running iOS 17.5.1) to restore the database and re-sync to the other device. No matter what I did, the importer would crash and import nothing. Apple Health generates thousands of data points every month. If, like me, you have a years-long database, with hundreds of thousands of data points, and need to restore it, forget it. This app will just crash and not import anything. I needed to provide my Apple Health data to my health care providers and now all I have are two unusable XML files. This developer should be thankful my personal resources are limited. Because this kind of data loss is the stuff lawsuits are made of. Update: The free Health XML Splitter Mac desktop app —designed to break up large Apple Health XML databases into smaller chunks that Health Importer can use— also doesn’t work. All it did was create one highly compressed database that also made Health Importer crash.
