Verdict

The call

The clearest difference is in-app purchases: DeTech at none against Bedtime Blocker's 1. DeTech also leads on iOS requirement (17.6 vs 26.2). Bedtime Blocker's advantage is review sentiment (100% vs 67%) and update cadence (every 3 days vs fortnightly). On price, ads and device support there is nothing between them.
