# Typus vs Reefability

The clearest difference is rating: Typus at 5.0 against Reefability's 3.1. Typus also leads on iOS requirement (13.0 vs 15.0.0). Reefability's advantage is review sentiment (38% vs 0%) and update cadence (daily vs monthly). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Typus sells 2 in-app purchases, starting at $0.99 per month and Reefability sells 9 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Typus holds the better App Store score, 5.0 against 3.1. That said, the two scores are not equally well evidenced: Reefability has 36 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of Typus's written reviews are positive against 38% of Reefability's, so the app with the better star average is not the one people write more warmly about.

Typus ships an update monthly, Reefability daily. The most recent releases landed on October 8, 2026 and October 20, 2026 respectively.
