# Reefability vs Aquarium Tracker

The clearest difference is rating: Aquarium Tracker at 4.8 against Reefability's 3.2. Reefability's advantage is review sentiment (38% vs 0%) and update cadence (daily vs every 10 days). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Reefability sells 9 in-app purchases, starting at $9.99 per month and Aquarium Tracker sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Aquarium Tracker holds the better App Store score, 4.8 against 3.2. That said, the two scores are not equally well evidenced: Reefability has 38 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 38% of Reefability's written reviews are positive against 0% of Aquarium Tracker's, so the app with the better star average is not the one people write more warmly about.

Reefability ships an update daily, Aquarium Tracker every 10 days. The most recent releases landed on October 27, 2026 and October 24, 2026 respectively.
