Our verdict on WearLink
WearLink is a wearable health-data API for developers building fitness, clinical, wellness, insurance and research applications. It brings provider data into a common schema and offers REST access, hosted OAuth connections and mobile SDKs. Supported data includes sleep, heart rate, HRV, workouts, activity, weight, blood pressure and glucose. Its 14 named integrations span services such as Oura, WHOOP, Fitbit, Garmin, Dexcom and Eight Sleep, alongside Apple HealthKit, Google Health Connect and Samsung Health. The combination is aimed at teams that need to connect multiple health-data sources rather than build each provider integration separately.
The integration approach covers both cloud and on-device data. WearLink handles synchronization, backfills and revision re-delivery, and can send data through webhooks with signed payloads and retries; a REST API is available for querying it. Swift support covers on-device Apple HealthKit data, while Kotlin support covers Google Health Connect and Samsung Health. However, six of the listed providers are still in vendor OAuth onboarding, so the list of named integrations should not be read as a guarantee that all are currently connectable. This makes provider readiness worth checking against an application's requirements before committing to the service.
WearLink has a free Hobby plan with no card requirement or expiry and community support. Developer adds email support with a 48-hour response and 500 photo nutrition logs per day. Scale adds email and Slack support with a 24-hour response, while its availability is best-effort. Enterprise offers custom annual or custom terms, dedicated Slack support and dedicated infrastructure; a HIPAA BAA is available on request. Pick WearLink if a shared schema, multiple provider connections and delivery tooling matter more than owning integrations in-house. Teams that require every listed provider to be immediately connectable, or require a stated availability commitment at Scale, should assess those constraints before choosing it.
