# Subsurface vs DIVEROUT

The clearest difference is rating: Subsurface at 4.5 against DIVEROUT's 3.6. Subsurface also leads on in-app purchases (none vs 15). DIVEROUT's advantage is update cadence (every 5 days vs every 2 months). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. DIVEROUT sells 14 in-app purchases, starting at $0.99 per month. Subsurface asks for nothing beyond the download.

Subsurface holds the better App Store score, 4.5 against 3.6. Both are backed by a comparable volume of ratings — 48 and 18 respectively. Written reviews complicate that: 63% of Subsurface's written reviews are positive against 65% of DIVEROUT's, so the app with the better star average is not the one people write more warmly about.

Subsurface ships an update every 2 months, DIVEROUT every 5 days. The most recent releases landed on September 18, 2026 and September 21, 2026 respectively.
