SmartPlan is an Android-based measurement app that allows you to create floor plans with ease. Using augmented reality (AR) technology, you can measure the floor, walls, doors, and windows of any room with just your camera. The app supports both imperial and metric units, and you can even take a photo of your measurements for future reference.

One of the best features of SmartPlan is that it allows you to view your floor plans in both 2D and 3D models, making it easier to visualize your space. You can also view the floor and walls separately, giving you a better idea of how your design will look. Once you've created your floor plan, you can easily share it via email, message, or any other preferred method.

Overall, SmartPlan is an excellent app for anyone looking to create a floor plan quickly and easily. Its user-friendly interface and AR technology make it a must-have for homeowners, architects, and interior designers alike.
