TrainerMetrics Connect puts your personal training operation on your phone. Built for the gym floor, not the back office. Check a client's history before they walk in, log an assessment between sets, and message your team without switching apps. FOR TRAINERS AND MANAGERS Run your day from one place. • See your schedule, open tasks, and events the moment you open the app • Review a client's full history, goals, and metrics before every session • Build and assign multi-week programs, then copy a week forward in seconds • Capture assessments and body composition results on the spot • Message clients and staff without leaving the platform • Track which clients are overdue, unassigned, or missing paperwork FOR CLIENTS Your trainer can invite you to work alongside them in the same app. • See your assigned workouts, sessions, and tasks so you always know what is next • Follow your progress with body composition, fitness test results, and progress photos • Message your trainer directly, without giving out your personal phone number • Open trainer notes and reference videos so you are never guessing about form • Find your intake forms and test results in one place RESULTS HAPPEN BETWEEN SESSIONS A trainer sees a client two or three hours a week. 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. BEFORE YOU DOWNLOAD TrainerMetrics Connect requires an account. Trainers and managers sign in with the credentials their facility provided. Clients need an invitation from their trainer to get started. If your facility does not use TrainerMetrics yet, visit trainermetrics.com to request a demo. Questions or trouble signing in?

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
