Verdict

The call

The clearest difference is rating: Tri at 5.0 against Chess Online's 4.5. Tri also leads on ads (none vs shown) and review sentiment (100% vs 71%). Chess Online's advantage is ratings volume (68 vs 3) and iOS requirement (15.0 vs 17.5). On price, update cadence, in-app purchases and device support there is nothing between them.
