About

Lidar Larry

Lidar Larry turns your iPhone into a room scanner. Point your device at a space, walk the perimeter slowly, and the app builds a 3D model with walls, doors, windows, and furniture in place. SCAN ONE ROOM OR A WHOLE HOUSE Capture a single bedroom, kitchen, or office—or keep going and merge multiple rooms into one house scan. Reopen saved scans anytime from your library, rename them, or split a house back into individual rooms when you need to. MEASUREMENTS YOU CAN ACTUALLY USE See wall lengths, door and window sizes, and furniture footprints in metric or imperial. Switch units with one tap. The 2D floor plan shows dimensions right on the drawing so you do not have to guess from a static image. EXPLORE IN 3D View your scan in dollhouse or walkthrough mode. Orbit around the space, check proportions, and get a feel for the layout before you move furniture or start a renovation. EXPORT AND SHARE Send USDZ models for AR Quick Look, save floor plan images, or export styled room photos from corner and top-down angles. Standard quality is fast and light on memory; photoreal mode adds richer lighting and textures when you want something presentation-ready. BUILT FOR LiDAR DEVICES Lidar Larry requires an iPhone with a LiDAR scanner (iPhone 12 Pro and later Pro models). Scanning works best in good lighting when you move steadily and cover every wall and corner. Whether you are measuring for a remodel, documenting a rental, or just keeping a record of a space, Lidar Larry keeps the process simple: scan, measure, export.

Verdict

The call

The clearest difference is price: Seismometer+ at Free against Lidar Larry's $2.99. Seismometer+ also leads on device support (3 vs 1) and iOS requirement (15.0 vs 17.0). Lidar Larry's advantage is ads (none vs shown). On in-app purchases there is nothing between them.
