Verdict
The clearest difference is rating: Pace at 4.7 against KMetrix's 4.0. Pace also leads on ratings volume (386 vs 1). KMetrix's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price, update cadence and device support there is nothing between them.

Both are free to download. Pace sells 1 one-off in-app purchase. KMetrix asks for nothing beyond the download.
Pace holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Pace has 386 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 88% of KMetrix's written reviews are positive against 75% of Pace's, so the app with the better star average is not the one people write more warmly about.
KMetrix ships an update monthly, Pace every 6 weeks. The most recent releases landed on October 9, 2026 and October 20, 2026 respectively.
