Verdict

The call

The clearest difference is price: Lock In! Game at Free against Chess's $3.99. Lock In! Game also leads on rating (5.0 vs 4.7) and review sentiment (100% vs 92%). Chess's advantage is ratings volume (118 vs 9) and iOS requirement (15.0 vs 17.2). On ads, in-app purchases, monetization model and device support there is nothing between them.
