# Sky Castle vs NemOZ

The clearest difference is update cadence: NemOZ at every 3 weeks against Sky Castle's every 3 months. NemOZ also leads on review sentiment (100% vs 83%). Sky Castle's advantage is ratings volume (27 vs 4) and iOS requirement (11.0 vs 15.0). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Sky Castle sells 1 one-off in-app purchase and NemOZ 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 — 4.9 for Sky Castle against 5.0 for NemOZ. That said, the two scores are not equally well evidenced: Sky Castle has 27 ratings behind it against 4, so its average is the more settled of the two. Written reviews are what separate them: 83% of Sky Castle's written reviews are positive against 100% of NemOZ's.

Sky Castle ships an update every 3 months, NemOZ every 3 weeks. The most recent releases landed on October 21, 2026 and October 30, 2026 respectively.
