# Subsurface vs Dive Check

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.

Both are free to download. Dive Check sells 1 one-off in-app purchase. Subsurface asks for nothing beyond the download.

Subsurface holds the better App Store score, 4.5 against 1.0. That said, the two scores are not equally well evidenced: Subsurface has 48 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 63% of Subsurface's written reviews are positive against 50% of Dive Check's.

Subsurface ships an update every 2 months, Dive Check every 4 days. The most recent releases landed on October 22, 2026 and October 24, 2026 respectively.
