Verdict

The call

The clearest difference is in-app purchases: PiyoChess at none against Ocean Chess's 6. PiyoChess also leads on ads (none vs shown) and iOS requirement (13.0 vs 15.0). Ocean Chess's advantage is update cadence (every 5 days vs every 3 weeks). On price and device support there is nothing between them.
