Verdict
The clearest difference is in-app purchases: Boardmates at none against CelestialChess's 1. Boardmates also leads on update cadence (every 3 weeks vs every 2 months). CelestialChess's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
