# Somnus vs Sky Castle

The clearest difference is ads: Somnus at none against Sky Castle's shown. Somnus also leads on update cadence (every 6 days vs every 3 months) and monetization model (free vs free with in-app purchases). On price, rating, review sentiment and in-app purchases there is nothing between them.

Both are free to download. Somnus sells 2 one-off in-app purchases and Sky Castle 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 — 4.8 for Somnus against 4.9 for Sky Castle. That said, the two scores are not equally well evidenced: Somnus has 230 ratings behind it against 25, so its average is the more settled of the two. Written reviews split almost evenly too, at 83% and 83% positive.

Somnus ships an update every 6 days, Sky Castle every 3 months. The most recent releases landed on September 1, 2026 and September 25, 2026 respectively.
