Verdict
The clearest difference is price: DPI at Free against Image Size PRO's $59.99. DPI also leads on ratings volume (1.1K vs 56). Image Size PRO's advantage is review sentiment (100% vs 60%) and in-app purchases (none vs 1). On rating, device support and iOS requirement there is nothing between them.
