# Smart Reef vs REEFB

The clearest difference is rating: REEFB at 3.0 against Smart Reef's 1.6. REEFB also leads on in-app purchases (none vs 11). Smart Reef's advantage is ratings volume (19 vs 1). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Smart Reef sells 8 one-off in-app purchases. REEFB asks for nothing beyond the download.

REEFB holds the better App Store score, 3.0 against 1.6. That said, the two scores are not equally well evidenced: Smart Reef has 19 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 4% of Smart Reef's written reviews are positive against 0% of REEFB's, so the app with the better star average is not the one people write more warmly about.

Smart Reef ships an update every 3 months, REEFB every 2 months. The most recent releases landed on October 16, 2026 and October 11, 2026 respectively.
