One of them (Instinct) saved me from having to pay a cancellation fee on a restaurant reservation when it noticed I had accidentally booked the reservation for the week before I was going to be in that city. It proactively reached out to me to suggest I check on it.
I would have figured it out eventually on my own - but likely not until my calendar fired a "time to leave" notification and then I'd have to pay the cancellation fee and place an awkward call to the restaurant.
