# Key vs LeaperKim

The clearest difference is rating: Key at 4.0 against LeaperKim's 2.9. LeaperKim's advantage is update cadence (every 10 days vs every 6 months) and review sentiment (22% vs 0%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Key holds the better App Store score, 4.0 against 2.9. Both are backed by a comparable volume of ratings — 5 and 15 respectively. Written reviews complicate that: 0% of Key's written reviews are positive against 22% of LeaperKim's, so the app with the better star average is not the one people write more warmly about.

Key ships an update every 6 months, LeaperKim every 10 days. Both last shipped on October 24, 2026.
