iOS: If you like to use Apple's Health app, you've probably noticed there's no good way to import or export your data. That's fine for most people who use iCloud to restore their device, but if you prefer to set up a new iPhone instead, it loses that data. Health Data Importer rescues it.
Health Data Importer does exactly what the name suggests. Download the app, then load it up on your fresh new iPhone. It will scan your iCloud backups for any health data, then import all of it over to your new phone. It's a niche circumstance, but it's a welcome solution to an annoying problem for those of us who prefer to set up a new phone from scratch.
