Verdict
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.
