Verdict
The clearest difference is ads: Sunbeam at none against SimpleMoon's shown. Sunbeam also leads on update cadence (every 4 weeks vs every 5 months) and ratings volume (1.7K vs 302). SimpleMoon's advantage is review sentiment (86% vs 70%) and rating (4.9 vs 4.7). On price, in-app purchases, monetization model and device support there is nothing between them.
