See your progress more clearly. Depthline turns your weight journey into a calm underwater voyage, helping you focus on meaningful change over time. Weight changes day to day. Direction matters more. Depthline is a weight-trend tracker designed to make long-term progress easier to understand. Log a weigh-in manually or optionally import weight measurements from Apple Health. Depthline turns your history into a smoothed trend, then carries a small submarine along the course so you can see where you are going without overreacting to a single number. SEE THE TREND Separate the broader direction from normal daily fluctuation with a clear, focused trend view. FOLLOW YOUR VOYAGE Watch your submarine move through a visual journey shaped by your real weight history. KEEP A LOGBOOK Review past measurements and understand how the journey has developed over time. USE APPLE HEALTH With your permission, Depthline can read body-mass measurements from the Health app and use them throughout the core experience—including the trend, Voyage, and Logbook. Apple Health access is optional, and manual logging remains available. CALM BY DESIGN No feeds, streak pressure, calorie counting, or judgment. Depthline focuses on one job: helping you see the direction behind the number.
