# K vs Notebook Games

The clearest difference is ads: Notebook Games at none against K's shown. Notebook Games also leads on monetization model (free vs free with in-app purchases). K's advantage is update cadence (every 2 days vs fortnightly) and iOS requirement (15.0 vs 17.0). On price, rating, ratings volume and in-app purchases there is nothing between them.

Both are free to download. K sells 1 one-off in-app purchase and Notebook Games sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for K against 5.0 for Notebook Games. Both are backed by a comparable volume of ratings — 1 and 1 respectively.

K ships an update every 2 days, Notebook Games fortnightly. Both last shipped on October 31, 2026.
