That's true, it apparently has some multiple choice questions you can answer, which is definitely better than just hitting the big red button and letting rescuers guess what the nature of the situation is based on you position. Being two-way, the other advantage of the inreach is that rescuers can ask you questions and tell you when they expect to arrive etc. That said, the delta in functionality between what the iphone will offer and what an inreach offers in an emergency situation is probably not enough for the vast majority of people to want to purchase an inreach and a subscription, unless they also have a use for non-emergency communication outside of cell coverage.
