Do you love rust? Or maybe corrosion is your nemesis? SpotRust uses deep learning AI on your iPhone to detect rusty things - specifically ferrous corrosion. Use your own photos you've taken over the years of rust, take a picture of something being eaten away by salt, or use live mode to explore the oxidation around you. SpotRust is a work in progress, and you can help to improve its detection by submitting your photos to our dataset.

The clearest difference is ads: Spot Rust at none against IMARC's shown. IMARC's advantage is update cadence (every 4 days vs every 4 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
