Verdict
The clearest difference is price: WWPass Key at Free against SDR's $49.99. WWPass Key also leads on rating (4.9 vs 4.2) and review sentiment (100% vs 78%). SDR's advantage is update cadence (every 2 weeks vs every 3 months) and ratings volume (70 vs 10). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
