I agree that the “It looks like you’ve…” informal-chatty style is terrible. It’s hilarious that they describe it as “straightforward and direct”. It should rather be something short and matter-of-fact like “Hard fall detected.”
The tone of "Hard fall detected" is good if you're developing a product where precision and accuracy matters most such as in the military or in some high stake business situations. But the Apple Watch is a consumer product.
Also, the watch did not detect a hard fall. It merely saw signals that suggests it could be a fall.
So "It looks like you've" is more accurate and friendly to consumers..
