What's New in Matter
3.3.8
October 30, 2026
TIMED WORKOUTS AMRAP, EMOM, For Time, Tabata, Intervals and Circuit blocks run in a full-screen timer that shows the round, the work or rest phase, and what comes next. Round and phase changes arrive as lock-screen alerts, and the Live Activity shows the current phase. When a block finishes, its score (rounds and reps, or your finish time) is saved and sent to your coach with the session. A NEW HOME Today's session from your coach leads the screen, with readiness, recovery, strain and sleep underneath. Rearrange, hide and restore Home cards from the Add cards tray. MESSAGES Conversations with several named coaches and your team, in one list. INTERVALS.ICU Connect Intervals.icu from Devices and apps with guided API-key setup. YOUR WEARABLE'S NIGHT If you sleep in a WHOOP, your sleep, HRV and resting heart rate now come from it, and recovery and readiness are scored from that night against its own baseline. REDESIGNED, SCREEN BY SCREEN One design system in light and dark, text that follows your text-size setting, motion that respects Reduce Motion, and VoiceOver labels on every control. Recovery, sleep, strain, readiness, training load, energy, stress and weight each lead with today's value, what it means, and the trend. MOVING TIME Every completed workout now shows moving time. When the elapsed clock ran a lot longer, a short note says so. FIXES - Recording an assigned workout on the phone and Apple Watch at the same time no longer counts the session twice. - Failed workout syncs retry, and a recent HealthKit replay recovers missing wearable measurements. - AI changes that affect your coach or your plan arrive as Approve cards; a failed Approve says so instead of showing a raw server error.
