Verdict
The clearest difference is in-app purchases: Leascope at none against Notevision's 1. Leascope also leads on update cadence (daily vs weekly) and rating (5.0 vs 4.8). Notevision's advantage is ratings volume (3.2K vs 1). On price, ads, device support and iOS requirement there is nothing between them.
