Many people won't agree with this opinion, but for me my favorite part of the LG G3 is the LG Health. I've been trying to get into shape recently after my doctor told me that I'd have increased chance of a heart attack with my lifestyle, and having something like what LG did built right into the phone is incredibly appealing. While I know there are some great third-party apps and hardware available, it's nice to think that companies think about that part of a consumer's life when designing phones.
