Verdict

The call

The clearest difference is review sentiment: The Articles at 79% against Codex4's 50%. The Articles also leads on ratings volume (148 vs 2) and iOS requirement (13.0 vs 15.6). Codex4's advantage is update cadence (every 4 days vs every 3 weeks) and rating (5.0 vs 4.8). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Codex4 holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: The Articles has 148 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 79% of The Articles's written reviews are positive against 50% of Codex4's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

The Articles ships an update every 3 weeks, Codex4 every 4 days. The most recent releases landed on October 16, 2026 and October 4, 2026 respectively.
