Between private home showings and public open house events, selling your house can bring a slew of strangers through your door. There’s a new app to help you and your real estate professional keep track of who’s who: SafeShowings, available now for iOS and Android. The SafeShowings app provides an easy, mobile way for real estate professionals to scan in visitors’ drivers licenses prior to showing a home. The app stores an image of the individual’s license alongside the listing info and agent information. It keeps an ongoing list of people who have entered the home and when they were there, which can then be accessed via the app or on the web.
