# ReefBay vs App

The clearest difference is ads: App at none against ReefBay's shown. App also leads on review sentiment (94% vs 83%) and iOS requirement (13.0 vs 16.4). ReefBay's advantage is ratings volume (479 vs 17). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. ReefBay sells 4 in-app purchases, starting at $4.99 per month and App sells 5 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for ReefBay against 4.8 for App. That said, the two scores are not equally well evidenced: ReefBay has 479 ratings behind it against 17, so its average is the more settled of the two. Written reviews are what separate them: 83% of ReefBay's written reviews are positive against 94% of App's.

ReefBay ships an update every 8 days, App fortnightly. The most recent releases landed on October 30, 2026 and October 28, 2026 respectively.
