# iDfish vs Scuba Diving Computer Oceanic+

The clearest difference is monetization model: Scuba Diving Computer Oceanic+ at free with in-app purchases against iDfish's subscription. Scuba Diving Computer Oceanic+ also leads on rating (4.4 vs 3.9) and update cadence (every 3 weeks vs every 6 months). iDfish's advantage is review sentiment (88% vs 62%) and iOS requirement (15.6 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. iDfish sells 5 in-app purchases, starting at $5.99 per year and Scuba Diving Computer Oceanic+ sells 7 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Scuba Diving Computer Oceanic+ holds the better App Store score, 4.4 against 3.9. That said, the two scores are not equally well evidenced: Scuba Diving Computer Oceanic+ has 4.7K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 88% of iDfish's written reviews are positive against 62% of Scuba Diving Computer Oceanic+'s, so the app with the better star average is not the one people write more warmly about.

iDfish ships an update every 6 months, Scuba Diving Computer Oceanic+ every 3 weeks. The most recent releases landed on October 14, 2026 and October 15, 2026 respectively.
