Verdict

The call

The clearest difference is in-app purchases: NAOs 公式アプリ at none against Sleep Tracker's 18. NAOs 公式アプリ also leads on ads (none vs shown) and iOS requirement (12.0 vs 15.0). Sleep Tracker's advantage is update cadence (every 3 weeks vs every 38 months). On price and device support there is nothing between them.
