Verdict
The clearest difference is review sentiment: CozyKey Pro at 77% against StoneKey's 6%. CozyKey Pro also leads on rating (4.2 vs 3.6) and ratings volume (102 vs 5). StoneKey's advantage is update cadence (every 3 weeks vs every 4 months) and price ($1.99 vs $2.99). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
