# Millisecond Clock vs ms clock

The clearest difference is rating: Millisecond Clock at 4.7 against ms clock's 4.2. Millisecond Clock also leads on ratings volume (131 vs 10). ms clock's advantage is in-app purchases (none vs 3) and update cadence (every 2 months vs every 6 months). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Millisecond Clock sells 3 one-off in-app purchases. ms clock asks for nothing beyond the download.

Millisecond Clock holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Millisecond Clock has 131 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 73% of Millisecond Clock's written reviews are positive against 80% of ms clock's, so the app with the better star average is not the one people write more warmly about.

Millisecond Clock ships an update every 6 months, ms clock every 2 months. The most recent releases landed on October 1, 2026 and October 11, 2026 respectively.
