Bone mass changes slowly over years. Logging it consistently builds a long-term health record that is hard to get from any single app.
HC Webhook sends bone mass readings to any webhook — here are ideas to get you started.
Store bone mass readings in a spreadsheet or database to build a multi-year skeletal health history.
Add bone mass to your Airtable or Notion health profile alongside weight, body fat, and lean mass.
Include bone mass in a yearly health summary email comparing this year to previous years.
Plot bone mass, lean mass, and fat mass together in Grafana to see how your body composition breaks down.
HC Webhook posts a JSON object containing a bone_mass array to your endpoint on every sync.

}Google Health Connect stores your bone mass data from compatible apps (Samsung Health, Fitbit, Garmin, and more). HC Webhook reads that data on a schedule you set and forwards it as JSON to any URL you add — n8n, Home Assistant, Zapier, or your own API.
Install HC Webhook and grant Health Connect permission for Bone Mass.
Paste your webhook URL — Home Assistant, n8n, Zapier, or any endpoint.
Set your sync schedule. Bone Mass readings arrive automatically, every time.
