SecondFloor review
A privacy-focused iOS scanner for measured 2D and 3D floor plans.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SecondFloor is a mobile floor plan scanning app for LiDAR-equipped iPhones and iPads. It is designed for people who need measured room layouts rather than plans generated from prompts or uploaded images. During scanning, AI detects walls, windows, doors, and fixed furniture, while LiDAR captures room measurements. The app produces a 2D top-down floor plan and a 3D map with real-time scanning feedback. Users can add custom room labels, edit walls, doors, and windows on the device, share completed plans, and export them as images or PDFs.
The main differentiator is its on-device workflow. Floor plan data is processed without cloud upload, which suits users who prioritize keeping scans on their device. The editing tools also stay within the app, allowing adjustments to walls, doors, and windows after capture. Unlimited floor plan scanning is included with a subscription, while access is offered through a Day Pass, Weekly Subscription, Monthly Subscription, or Yearly Subscription. New subscribers receive a one-week free trial, and the listed starting price is 9.99.
SecondFloor fits iPhone and iPad users who have compatible LiDAR hardware and want a focused scanning workflow with both 2D and 3D outputs. Its image and PDF export options make the results easier to share outside the app, and built-in sharing supports direct distribution of completed plans. The trade-offs are significant for broader use: the app is iOS-only, requires LiDAR-equipped hardware, and does not offer a free plan. Choose it for private, device-based room scanning and editing; consider another tool if you need Android support, non-LiDAR capture, prompt-to-plan generation, or image-to-plan conversion.
