Verdict
The clearest difference is price: Oceanodesy at Free against 3pLevel Pro's $4.99. Oceanodesy also leads on rating (4.5 vs 3.5) and update cadence (every 4 weeks vs every 14 months). 3pLevel Pro's advantage is review sentiment (100% vs 73%). On ads, in-app purchases and device support there is nothing between them.

Oceanodesy is free to download; 3pLevel Pro costs $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Oceanodesy holds the better App Store score, 4.5 against 3.5. Both are backed by a comparable volume of ratings — 6 and 2 respectively. Written reviews complicate that: 73% of Oceanodesy's written reviews are positive against 100% of 3pLevel Pro's, so the app with the better star average is not the one people write more warmly about.
Oceanodesy ships an update every 4 weeks, 3pLevel Pro every 14 months. The most recent releases landed on October 16, 2026 and October 25, 2026 respectively.
