What's New in Marrow Health
1.1
September 3, 2026
Sets are logged as reps x weight, the way you count them mid-set, and every set row is the same height. Minimize a workout to a banner and keep using the rest of the app. The timer keeps counting; one tap brings the logger back. Back out of an accidental Finish. The session and its Apple Health workout are rolled back as if it never happened. Search finds what you typed: exact names first, extra words cost, and exercises trained this week wear a small clock. Tap any diary entry to change today's portion in place, or copy a past meal into today at any amount. Quick-log buttons flash a check when the tap lands. Add a line of detail to a meal photo before it scans, for what the camera cannot see. The scan banner clears itself after five seconds.
