Verdict
The clearest difference is price: Tri at Free against Block Chess's $0.99. Tri also leads on update cadence (every 3 weeks vs every 11 months). Block Chess's advantage is in-app purchases (none vs 2) and iOS requirement (10.0 vs 17.5). On ads and device support there is nothing between them.
