Optical Surface Recognition vs StressTable2023
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.
StressTable2023
Access material stress, physical, and mechanical properties from ASME Sec II-D. This utility provides quick determination of properties at specific temperatures for various tables, aiding in hand calculations where commercial software is unavailable.
- ASME Sec II-D material properties
- Stress values at given temperatures
- Physical and mechanical properties
- Metric and US customary units
- Hand calculation assistance
- Supports multiple ASME tables

Background ASME Sec II-D give the material stress, physical and mechanical properties table. There are some tools available for Table 1-A stress values determination at given temperature but no tool available for other tables for quick determination of properties at given temperature. Applicable Code / Edition & Standards This app is based on ASME Section II-D 2023 Edition for metric and US customary unit. Utility This app gives material properties at given temperature for different Code section, also help user to do the hand calculation using the values where no commercial design software is available in the market. Competitive Edge There is no app available in the market to cover most of the tables available in ASME II-D for material properties. This app fills that gap and facilitate user to use these values in hand calculation where no commercial software is available for particular Code section. Target Audience This app targets inspection agencies, pressure items manufacturing organizations, quality control personnel, Engineers and designers who are involved in pressure items design calculations. Non Consumable Subscription: You can download the app from App Store for free, however One time Non-Consumable subscription in-app-purchase is required before you can use any of the Tables of this app. Purchase can be made by going to the menu of the application. Terms and condition are also provided there.
