# Codex vs Liquid Apollo

The clearest difference is review sentiment: Liquid Apollo at 68% against Codex's 0%. Liquid Apollo also leads on in-app purchases (none vs 3) and ratings volume (653 vs 3). Codex's advantage is rating (4.7 vs 4.5) and iOS requirement (11.0 vs 18.0). On price, ads and device support there is nothing between them.

Both are free to download. Codex sells 3 in-app purchases, starting at $0.99 per 7 days. Liquid Apollo asks for nothing beyond the download.

Codex holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Liquid Apollo has 653 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 0% of Codex's written reviews are positive against 68% of Liquid Apollo's, so the app with the better star average is not the one people write more warmly about.

Codex ships an update monthly, Liquid Apollo every 10 days. The most recent releases landed on October 14, 2026 and October 18, 2026 respectively.
