Verdict

The call

The clearest difference is rating: Oceanic+ Scuba Diving Computer at 4.4 against iDfish's 3.9. Oceanic+ Scuba Diving Computer also leads on monetization model (free with in-app purchases vs subscription) and update cadence (every 4 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 Oceanic+ Scuba Diving Computer sells 7 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Oceanic+ Scuba Diving Computer holds the better App Store score, 4.4 against 3.9. That said, the two scores are not equally well evidenced: Oceanic+ Scuba Diving Computer 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 Oceanic+ Scuba Diving Computer's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

iDfish ships an update every 6 months, Oceanic+ Scuba Diving Computer every 4 weeks. The most recent releases landed on November 2, 2026 and November 4, 2026 respectively.
