# Reefability vs ReefDose

The clearest difference is review sentiment: ReefDose at 100% against Reefability's 38%. ReefDose also leads on rating (5.0 vs 3.2). Reefability's advantage is update cadence (daily vs every 11 days) and ratings volume (37 vs 3). 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 ReefDose sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

ReefDose holds the better App Store score, 5.0 against 3.2. That said, the two scores are not equally well evidenced: Reefability has 37 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 38% of Reefability's written reviews are positive against 100% of ReefDose's.

Reefability ships an update daily, ReefDose every 11 days. The most recent releases landed on October 25, 2026 and October 17, 2026 respectively.
