# Units vs Cat Keyboard

The clearest difference is review sentiment: Cat Keyboard at 83% against Units's 45%. Cat Keyboard also leads on update cadence (fortnightly vs every 5 weeks). Units's advantage is ratings volume (261 vs 9) and rating (4.9 vs 4.7). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Units sells 3 in-app purchases, starting at $0.99 per month and Cat Keyboard sells 4 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Units holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Units has 261 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 45% of Units's written reviews are positive against 83% of Cat Keyboard's, so the app with the better star average is not the one people write more warmly about.

Units ships an update every 5 weeks, Cat Keyboard fortnightly. The most recent releases landed on September 23, 2026 and September 8, 2026 respectively.
