# PRO CHARTS vs OceanFishMap

The clearest difference is rating: OceanFishMap at 5.0 against PRO CHARTS's 4.5. OceanFishMap also leads on update cadence (fortnightly vs every 2 months) and iOS requirement (13.4 vs 15.6). PRO CHARTS's advantage is ratings volume (8.5K vs 1) and chart position (#182 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. PRO CHARTS sells 4 in-app purchases, starting at $2.99 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: PRO CHARTS has 8.5K ratings behind it against 1, so its average is the more settled of the two.
