I partially agree. I think, first, it's necessary to make a commitment to breaking the addiction, and then raise the level of awareness in order to follow through with that commitment. I believe an app can help detect addictive triggers and help a person move from an "impulsive and automatic mental state" to a "state of awareness."
Yeah they can help! I guess it would be good for apps to add to their message the call out to not over rely on them and seek help. Some cases are serious and this could be a bandaid fix that serious people rely on to tell themselves they are fine.
