# Repeat Timer vs Codex Calc

The clearest difference is price: Repeat Timer at Free against Codex Calc's $0.99. Repeat Timer also leads on rating (4.5 vs 4.0) and update cadence (monthly vs every 6 months). Codex Calc's advantage is review sentiment (100% vs 64%) and in-app purchases (none vs 7). On ads and device support there is nothing between them.

Repeat Timer is free to download; Codex Calc costs $0.99 up front. Repeat Timer sells 7 in-app purchases, starting at $2.99 per month. Codex Calc asks for nothing beyond the download.

Repeat Timer holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Repeat Timer has 7.4K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 64% of Repeat Timer's written reviews are positive against 100% of Codex Calc's, so the app with the better star average is not the one people write more warmly about.

Repeat Timer ships an update monthly, Codex Calc every 6 months. The most recent releases landed on September 24, 2026 and June 5, 2026 respectively.
