Depthline

Give each weigh-in some perspective.

Daily scale readings move with water, timing, sleep, food, and ordinary fluctuation. Depthline keeps the smoother direction visible without turning weight tracking into a sprawling health dashboard.

What Depthline does

The weight trend stays central. Body-composition or broader health scoring does not take over the app.

Smooth daily scale readings into a more useful weight trend.
Log readings manually without connecting Apple Health.
Import your approved body-weight history from Apple Health when you allow it.
Keep sparse-data states honest while the trend is still forming.
Review every reading in the Log and export your records as CSV.
In version 1.3, explore every History and Voyage range and every vessel style without a purchase.

Who it is for

Depthline is for people who already weigh themselves but find a single morning number too noisy to be useful. It provides calmer context without adding calorie tracking, diet rules, or a generic health score.

It is a personal trend utility, not a medical device, diagnostic tool, coach, or promise of a particular outcome.

Privacy

Your readings stay under your control.

Depthline stores manual readings and app settings locally. If you grant permission, it can read body-weight readings from Apple Health. Access is optional and read-only; Depthline does not write readings to Health.

There is no Depthline account or server for your weight readings. CSV export is initiated by you through the iOS share sheet.
