# K vs Krok

The clearest difference is rating: K at 4.8 against Krok's 1.0. K also leads on ratings volume (127 vs 1). Krok's advantage is update cadence (every 3 weeks vs every 5 months) and review sentiment (57% vs 42%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. K sells 3 one-off in-app purchases and Krok sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

K holds the better App Store score, 4.8 against 1.0. That said, the two scores are not equally well evidenced: K has 127 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 42% of K's written reviews are positive against 57% of Krok's, so the app with the better star average is not the one people write more warmly about.

K ships an update every 5 months, Krok every 3 weeks. The most recent releases landed on September 17, 2026 and September 23, 2026 respectively.
