# Codex4 vs Bragi

The clearest difference is rating: Codex4 at 5.0 against Bragi's 4.5. Codex4 also leads on update cadence (every 4 days vs every 3 weeks). Bragi's advantage is ratings volume (164 vs 2) and review sentiment (63% vs 50%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Codex4 sells 4 in-app purchases, starting at $12.99 per month and Bragi sells 3 in-app purchases, starting at $6.99 per 7 days. 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: Bragi has 164 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 50% of Codex4's written reviews are positive against 63% of Bragi's, so the app with the better star average is not the one people write more warmly about.

Codex4 ships an update every 4 days, Bragi every 3 weeks. The most recent releases landed on September 17, 2026 and September 23, 2026 respectively.
