Verdict

The call

The clearest difference is rating: Somnee at 3.7 against Lumos Sleep's 2.8. Somnee also leads on review sentiment (63% vs 42%) and ratings volume (71 vs 13). Lumos Sleep's advantage is monetization model (free vs paid) and update cadence (fortnightly vs every 2 months). On price, ads, in-app purchases and iOS requirement there is nothing between them.
