# C vs OceanFishMap

The clearest difference is rating: OceanFishMap at 5.0 against C's 4.5. OceanFishMap also leads on update cadence (fortnightly vs every 6 weeks) and iOS requirement (13.4 vs 15.1). C's advantage is ratings volume (2.3K vs 1) and chart position (#102 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. C sells 10 in-app purchases, starting at $1.99 per month and OceanFishMap sells 4 in-app purchases, starting at $100.00 per month. Whichever you choose, the download price is not the number that matters.

OceanFishMap holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: C has 2.3K ratings behind it against 1, so its average is the more settled of the two.

C ships an update every 6 weeks, OceanFishMap fortnightly. The most recent releases landed on September 26, 2026 and September 8, 2026 respectively.
