Verdict

The call

The clearest difference is update cadence: Nautical Ship Flags at every 3 weeks against CES Trainer's every 11 months. Nautical Ship Flags also leads on ratings volume (15 vs 1) and device support (3 vs 1). CES Trainer's advantage is rating (5.0 vs 4.6) and monetization model (free vs free with in-app purchases). On price, ads and in-app purchases there is nothing between them.
