Verdict
The clearest difference is rating: Simple Pace at 4.5 against KMetrix's 4.0. Simple Pace also leads on ratings volume (32 vs 1) and update cadence (every 10 days vs monthly). KMetrix's advantage is in-app purchases (none vs 4) and review sentiment (88% vs 75%). On price, ads and device support there is nothing between them.

Both are free to download. Simple Pace sells 4 one-off in-app purchases. KMetrix asks for nothing beyond the download.
Simple Pace holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Simple Pace has 32 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 75% of Simple Pace's written reviews are positive against 88% of KMetrix's, so the app with the better star average is not the one people write more warmly about.
Simple Pace ships an update every 10 days, KMetrix monthly. The most recent releases landed on September 24, 2026 and August 15, 2026 respectively.
