Verdict

The call

The clearest difference is rating: Subsurface at 4.5 against Dive Check's 1.0. Subsurface also leads on in-app purchases (none vs 1) and ratings volume (48 vs 2). Dive Check's advantage is update cadence (every 4 days vs every 2 months) and iOS requirement (8.0 vs 17). On price, ads and device support there is nothing between them.
