Depthline: Weight Tracker

Give each weigh-in some perspective. See an estimated trend, inspect the readings behind it, and understand longer changes. Now completely free, with no purchases.

A scale gives you a measurement. Depthline helps you understand the pattern across measurements.

See your recent weight trend beside the actual daily readings. The trend is a smoothed estimate, clearly distinguished from your latest measurement. Sparse histories and gaps stay visible. Weight loss, maintenance and gain are described without scores or judgment.

SEE THE PATTERN • Connect Apple Health Body Weight or log manually. • See your estimated trend on a dated chart with weight axes. • Inspect individual reading days and how multiple readings are combined. • Choose an optional target or range, or simply observe. • Check coverage, source differences and how the estimate is calculated.

EXPLORE YOUR HISTORY Inspect 30 days, 90 days, one year or all your history. Compare dated estimates when the readings support them. Missing days stay missing, and long gaps visibly restart the estimate.

KEEP YOUR RECORDS Unlimited manual records, your complete Log, editing and deletion of app-owned readings, CSV export, widgets and Shortcuts are included. Imported Health readings retain their source and stay read-only in Depthline. Depthline never writes to Apple Health.

AN OPTIONAL VOYAGE Explore an illustrated perspective on your history with every range and vessel style included. Voyage is symbolic; History provides the dated weight chart and supported comparisons.

COMPLETELY FREE Every feature is included. No upgrade, in-app purchase or subscription. Previous Depthline Plus purchasers keep all their features without another payment or a restore step. Your saved readings and settings remain intact when you update.

PRIVATE BY DESIGN No account, advertising or third-party analytics. Your readings remain on your device. Apple Health access is optional.

Depthline describes recorded weight and an estimate. It does not measure fat loss, explain the medical cause of a change, or provide medical advice.
