Verdict
The clearest difference is in-app purchases: ApprovalMax at none against Nautical Ops's 10. ApprovalMax also leads on ratings volume (35 vs 1). Nautical Ops's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 17.0). On price, rating, update cadence and ads there is nothing between them.
