Verdict

The call

The clearest difference is update cadence: Openings Mastermind at fortnightly against Shredder Chess Lite's every 7 months. Openings Mastermind also leads on rating (4.3 vs 4.0). Shredder Chess Lite's advantage is review sentiment (79% vs 50%) and ratings volume (20 vs 6). On price, ads, in-app purchases and monetization model there is nothing between them.
