Isn’t the poster replying on the options for downloading FLAC to a DAP on IOS?

What is the options for Android?

I don’t know of any native android solution that allows for sync to sync desktop or online platform for specifically FLAC files without a backend user/server/client service that is native.

What’s your alternative?

Android presents a filesystem when plugged in to a computer, so almost any file sync tool should work.
