# Nautical Ship Flags vs CES Trainer

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.

Both are free to download. Nautical Ship Flags sells 2 in-app purchases, starting at $0.99 per 7 days and CES Trainer sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

CES Trainer holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Nautical Ship Flags has 15 ratings behind it against 1, so its average is the more settled of the two.

Nautical Ship Flags ships an update every 3 weeks, CES Trainer every 11 months. The most recent releases landed on October 31, 2026 and October 27, 2026 respectively.
