The rest of the week is where progress is won or lost. Scheduled programming and in-app messaging keep the work going on the days clients train alone. BUILT TO CONNECT TrainerMetrics works alongside the systems your facility already runs, including member management platforms and body composition technology like InBody, so client records stay in one place instead of scattered across folders and spreadsheets.

Both are free to download. Interval Timer sells 6 in-app purchases, starting at $0.99 per month. TrainerMetrics Connect asks for nothing beyond the download.
TrainerMetrics Connect holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Interval Timer has 19K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 73% of Interval Timer's written reviews are positive against 0% of TrainerMetrics Connect's, so the app with the better star average is not the one people write more warmly about.
Interval Timer ships an update every 9 days, TrainerMetrics Connect every 6 days. The most recent releases landed on October 4, 2026 and October 3, 2026 respectively.
