Withings to Garmin Bridge

Automatically sync weight data from Withings smart scales to Garmin Connect. Solves the friction of manually entering data across multiple fitness platforms for users with both devices.

Wearable ownership is increasingly multi-device — Garmin dominates sports performance tracking while Withings leads in passive health monitoring, and the overlap audience is real and vocal on forums like r/Garmin. The closest substitute is Zapier or a manual IFTTT workaround, but neither handles OAuth token refresh and API quirks cleanly enough to be set-and-forget. At $500–1.5k/mo, the math only works with a low-touch subscription around $3–5/month and a few hundred paying users, which is achievable but leaves almost no room for support overhead or churn. The biggest risk is that Garmin or Withings ships native sync themselves — both companies have expanded their partner integrations in recent years, and a first-party solution would kill the product overnight with zero warning.
