Point. Detect. Measure. CorroScan finds corrosion with on-device AI and measures its true area with LiDAR — geotagged, logged, and PDF-ready in seconds.CorroScan turns your iPhone into a corrosion inspection instrument. Point the camera at rusted steel: on-device AI outlines every corrosion patch live, and the LiDAR scanner measures its true surface area — no reference markers, no tape measures, no guesswork. DETECT — a corrosion-trained neural network segments patches in real time, with stable outlines that survive camera motion. Distance, angle and light guidance keep every capture reliable. MEASURE — LiDAR depth fused with the camera yields genuine surface area (cm²/m²) and span for each patch, with a stated tolerance. Multiple patches are measured individually and in total. LOCATE — every scan is geotagged with a site name, browsable on a map and in a searchable, filterable log. REPORT — generate clean A4 PDF defect reports with photo, outlines, measurements, GPS and capture conditions — ready to send from the field. FREE — 100 scans with full detection and measurement. Everything stays on your iPhone. CORROSCAN PRO (auto-renewable subscription, monthly or annual) — unlimited scans and PDF defect reports. 100% on-device: no account, no cloud, your data never leaves your iPhone. TEAMS — inspection companies equip their crews with organization seats, adding cloud sync and a web dashboard managed by the company. REQUIRES a LiDAR-equipped iPhone (iPhone 12 Pro or later Pro models). No ads, no tracking, no third-party analytics.

Verdict
The clearest difference is in-app purchases: WITMOTION at none against CorroScan's 2. WITMOTION also leads on device support (3 vs 1) and iOS requirement (15.6 vs 17.0). CorroScan's advantage is update cadence (every 2 days vs every 2 weeks). On price and ads there is nothing between them.
