# BLÜ vs Ocean

The clearest difference is rating: Ocean at 4.9 against BLÜ's 3.5. Ocean also leads on review sentiment (95% vs 55%) and update cadence (every 3 days vs fortnightly). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Ocean holds the better App Store score, 4.9 against 3.5. That said, the two scores are not equally well evidenced: Ocean has 1.1K ratings behind it against 17, so its average is the more settled of the two.
