Verdict

The call

The clearest difference is price: PsychWatch at Free against Dual's $4.99. PsychWatch also leads on review sentiment (100% vs 60%) and rating (5.0 vs 4.5). Dual's advantage is in-app purchases (none vs 3) and update cadence (every 3 weeks vs every 2 months). On ads and device support there is nothing between them.
