# Codex4 vs AI German Minute

The clearest difference is rating: Codex4 at 5.0 against AI German Minute's 4.5. Codex4 also leads on update cadence (every 4 days vs monthly). AI German Minute's advantage is ratings volume (45 vs 2). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Codex4 sells 4 in-app purchases, starting at $12.99 per month and AI German Minute sells 5 in-app purchases, starting at $12.99 per month. Whichever you choose, the download price is not the number that matters.

Codex4 holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: AI German Minute has 45 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 50% and 50% positive.
