Verdict
The clearest difference is price: Somnee at Free against BpExtract's $9.99. Somnee also leads on rating (3.7 vs 2.2) and review sentiment (64% vs 47%). BpExtract's advantage is update cadence (every 2 weeks vs every 2 months). On ads, in-app purchases and device support there is nothing between them.
