In the past few months, we have covered plenty of iPhone apps that use AI and computer vision to better serve you. Optical Surface Recognition is also interesting to look at. It uses computer vision to detect corrosion on metallic surfaces. You will be able to capture photos and record videos with an OSR corrosion score and save it to your media roll.
According to the developer, this app works on any type of metal, including bolts, signs, grates, and nails. You can download it for free.
