Introducing RoomScan, an app that can draw floor plans by itself, measurements and all. So when you’re remodeling, looks like you have a new friend. All you have to do is touch each wall as prompted in the app and it’ll create the floor plan and include measurements as well. Try out the free version that can store up to four rooms and then upgrade to RoomScan Pro if needed. Here’s the other thing — if the RoomScan app gets 40 solid reviews, the makers have promised to increase the capacity to 40 rooms for the free app. RoomScan Pro can do other things as well like allow you to add photos and notes to your floor plans. Exporting in DXF for AutoCAD and PDF is also available. Check out RoomScan in the App Store now.
