Skin appearance
Appearance metrics are recorded from each scan and followed against your own baseline.
Bring selected sleep, activity and health context from your Withings devices. Stella keeps connected context close to your scan history, without treating timing as proof of cause.
Optional · permission-based · availability varies by device, region and connected source
Start with a scan. Connect a platform only when it is useful to you.

Connect from Stella when you choose.These are the main Withings records Stella can place beside your skin history. Exact fields depend on the device, source app and permissions you grant.
Available sleep duration, depth and disturbance records from compatible Withings devices.
Steps, distance and exercise sessions you choose to make available.
Available heart-rate and related records kept as context, subject to device support and permissions.
Available weight, body-composition and water-percentage records from compatible Withings scales.
Stella keeps what the camera observes distinct from what a connection provides. You can compare the timing and decide what is worth watching next.

A pattern can help you ask a better question. It does not prove that one event caused a change in your skin.
A connection is optional. Review the requested categories before you approve them, and change or remove access later from Stella and the connected platform.
Connections are one optional layer. The scan, routine and notes remain visible as their own sources.
Take a scan first. Add connected context only when it helps you see the dates more clearly.
