Optical Surface Recognition vs Mileseey Optics
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Optical Surface Recognition
This utility app uses computer vision to scan surfaces for signs of corrosion on various metal types. It allows users to capture photos and record videos of detected corrosion, saving them with a proprietary score.
- Detects corrosion on various metal surfaces
- Scans flat metal, nails, bolts, signs, poles, grates
- Captures photos with corrosion score
- Records videos with corrosion score
- Saves media to device photo roll

Optical Surface Recognition (OSR) is a unique technology which can scan surfaces for signs of surface degradation (corrosion). It can also detect corrosion on almost any type of metal, including exposed flat metal, nails, bolts, signs, poles, and grates. PHOTOS Capture photos of corrosion and save to your device's photo roll along with the OSR corrosion score in a custom generated image. VIDEOS Record entire videos with the proprietary OSR corrosion score and save them to your photo roll.
