Verdict
The clearest difference is in-app purchases: Simple Depression Test at none against Depression Test⁺'s 2. Simple Depression Test also leads on update cadence (fortnightly vs every 6 months). Depression Test⁺'s advantage is review sentiment (80% vs 50%) and ratings volume (746 vs 13). On price, ads, device support and iOS requirement there is nothing between them.
