As a real estate agent, one of my go-to app recommendations for buyers and sellers alike is RoomScan. It allows you to digitally create a floor plan that is surprisingly accurate, all with little effort.

For sellers, that means we can easily create handouts for open houses. For buyers, it’s a fun and convenient way to measure whether their furniture will fit while they wait during a home inspection.

The best part: It’s simple to use. Just tap the phone once against each wall of a room, and the app will draw an outline of the room’s shape — and include measurements of the length of walls as well as the room’s total square footage.

The basic version costs $0.99 on iOS, though for $4.99 you can purchase the Pro version for more advanced features. The app is not available on Android.
