Enjoy state-of-the-art image segmentation on your iPhone or iPad. Unlike typical cutout apps that make you carefully brush or tap one subject at a time, Segment Anything uses the open-source SAM (Segment Anything Model) to understand what’s in your photo—and automatically break the whole image into its elements in one pass. People, objects, backgrounds: they’re structured for you, so you can select, refine, and cut out what you need far easier. All processing runs fully on device. No network required. We’ve optimized it for smooth, reliable performance on iPhone and iPad. In Pro mode, unlock: Add up to 50 “Add mask” areas (instead of 3). “Remove area” for finer control over your cutouts. Download cutout images to save, share, or use in other apps.

Verdict
The clearest difference is in-app purchases: ExPrimary at none against Segment Anything's 1. ExPrimary also leads on rating (5.0 vs 4.6) and iOS requirement (14.0 vs 18.0). Segment Anything's advantage is ratings volume (10 vs 1). On price, ads and device support there is nothing between them.
