An engineer at a major auto insurance company told me about an app they had for insurance appraisals. If a person got in an accident, they could open the app, take pictures of the damage, and see what how much they'd get back from insurance. The first version would send you back an appraisal almost immediately. He said they had to add a ~24 hour delay because a lot of people thought it was impossibly fast, and that their claim hadn't been reviewed thoroughly enough.
