# AquaticLog vs Smart Reef

The clearest difference is review sentiment: AquaticLog at 71% against Smart Reef's 4%. AquaticLog also leads on rating (4.2 vs 1.6) and update cadence (weekly vs every 3 months). Smart Reef's advantage is iOS requirement (14.6 vs 18.1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. AquaticLog sells 3 in-app purchases, starting at $4.99 per month and Smart Reef sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

AquaticLog holds the better App Store score, 4.2 against 1.6. That said, the two scores are not equally well evidenced: AquaticLog has 401 ratings behind it against 19, so its average is the more settled of the two. Written reviews point the same way: 71% of AquaticLog's written reviews are positive against 4% of Smart Reef's.

AquaticLog ships an update weekly, Smart Reef every 3 months. The most recent releases landed on September 21, 2026 and September 26, 2026 respectively.
