Verdict
The clearest difference is in-app purchases: 1 Toss at none against Next Chess Move's 1. 1 Toss also leads on review sentiment (100% vs 76%) and rating (4.8 vs 4.5). Next Chess Move's advantage is update cadence (monthly vs every 11 months) and ratings volume (129 vs 6). On ads, device support and iOS requirement there is nothing between them.
