Have you ever encountered such a situation?
I want to measure if the table can hold the newly purchased desk lamp, but the tape measure is missing.
I want to know if this wall painting will be crooked, but I don't have a spirit level at hand.
I want to plan the layout of the room, but I have no idea about the size.
The AR portable ruler is designed for these moments.
No need for a physical ruler, simply open the camera to measure.
What can it do for you?
Measure things
Aim at the object, click on it, and the length, height, and width will be displayed. Tables, cabinets, boxes, packages, everything has energy. There is no problem with vertical surfaces, just scan the walls, floors, and door frames with a camera.
Painting Room
Scan the entire room and automatically generate a 3D floor plan. It's easy to see where the door is, where the window is, and what the size is. Measure before moving, compare before buying furniture, to avoid finding that you can't fit it when you come back.
leveling
Hanging paintings, installing shelves, setting up projectors, placing your phone up, the digital bubble level will tell you if it's crooked. Accurate to 0.1 °, much more reliable than the naked eye.
