**Measure Spaces with Augmented Reality** Measure floor and wall areas, check distances, visualize furniture placement, and see whether objects fit your space—all using your iPhone's camera. sqftAR is a practical AR measurement tool for painting, pressure washing, landscaping, renovation, DIY projects, house hunting, and home planning. Whether you're a contractor estimating an area or a homeowner planning your next project, sqftAR helps you visualize and measure spaces with ease. **FIVE CORE FEATURES** **1. Area – Floor** Measure floor areas in square feet (ft²) or square meters (m²). Mark the corners of a floor to calculate its area. Save measurements with notes and review them later. **2. Area – Wall** Measure wall areas in ft² or m². Useful for painting, cleaning, renovation, and other home improvement projects. **3. Length** Measure the distance between two points using augmented reality. **4. Furniture** Place standard-sized virtual furniture in your surroundings to visualize how furniture fits and compare its size with the available space. **5. Size Checker** Enter an object's width, depth, and height to create a virtual 3D box. Place it in your surroundings to see how its dimensions compare with the available space. **HOW TO USE** **1. Area – Floor or Wall** - Select your preferred measurement unit (ft² or m²). - Tap "Area – Floor" or "Area – Wall" on the main menu. - Move your iPhone slowly to scan the surrounding area. - Find a flat floor or wall surface and wait for the blue square to appear. - Position the "+" pointer at the first corner. - Tap the screen to mark the corner with a red sphere. - Move clockwise or counterclockwise to the next corner and tap again. - Continue marking each corner. Do not mark the starting point twice. - Tap "Calc" to calculate the area. - To save the measurement, tap "Save," enter a note, and confirm. - Tap "Camera" to take a photo. - To access saved measurements, tap the file icon in the upper-right corner of the main menu. - Search your saved measurements to find specific records. - Tap a saved record to view its location and photo, if available. - To delete a record, swipe left on the corresponding row. Note: Occasionally, the orange AR-shaded area may extend beyond the outline or overlap. This visual effect does not affect the app's area calculation. **2. Length** - Tap "Length" on the main menu. - Move your iPhone slowly to scan the surrounding area. - Wait for yellow dots to appear on the target surface. - Position the "+" pointer at the starting point. - Tap the screen to mark the point with a red sphere. - Move to the endpoint and position the pointer. - Tap again to display the measured distance. - To start a new measurement, tap "Reset." - Tap "Camera" to take a photo. **3. Furniture** - Tap "Furniture" on the main menu. - Scan the surrounding area until the blue square appears on a flat floor surface. - Select a furniture item from the list. - Tap the screen to place the virtual furniture. - To rotate an item, touch it and slide your finger. - To move an item, long-press it and drag. - Tap "Add Another Item" to place additional furniture. - Tap "Info" to show or hide furniture dimensions. - Tap "Camera" to take a photo. Virtual furniture uses standard or typical dimensions to help you visualize the relative size of a space. **4. Size Checker** - Select your preferred measurement unit. - Enter the width, depth, and height of the object. - Select the surface on which to place the virtual box. - Tap "GO." - Move your iPhone to scan the surrounding area. - Wait for the blue square to appear on a suitable flat surface. - Tap the screen to place the virtual box. Use this feature to visualize an object's dimensions before purchasing or placing it in your space. **IMPORTANT NOTES** AR measurements are estimates and may vary with lighting, surfaces, and device movement. Verify measurements with professional tools when precision is required.
