Verdict
The clearest difference is ads: Krok at none against K's shown. K's advantage is update cadence (every 4 days vs every 3 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Krok sells 3 in-app purchases, starting at $1.99 per month and K sells 3 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Krok ships an update every 3 weeks, K every 4 days. The most recent releases landed on October 24, 2026 and October 8, 2026 respectively.
