Wearable & Device Integration
Wearable Integration
We connect your platform to Apple HealthKit, Android Health Connect, Bluetooth Low Energy (BLE) devices, and aggregators like Validic, with HIPAA-ready pipelines and FHIR-native data modeling, not brittle one-off SDK glue.

What is wearable integration?
Wearable integration is connecting smartwatches, fitness trackers and medical devices to your app and clinical systems so their readings arrive complete and in one format. Agnotic Technologies builds it through Apple HealthKit, Android Health Connect, Bluetooth Low Energy and aggregators such as Validic or Terra, with consent and HIPAA safeguards designed in.
Each source has its own units, sampling cadence, consent model and gaps, so one wearable is rarely one API.
We normalize units, remove duplicate samples, fill sync gaps and model every reading as a FHIR R4 Observation, so care, analytics and RPM billing work from one record.
What it is
How does one data layer serve every device?
Wearable and device integration connects consumer wearables, clinical BLE devices, and multi-vendor aggregators to your platform, then normalizes their output into a single clinical stream. Done well, it gives care teams a trustworthy, real-time view without exposing them to a dozen vendor quirks.
We decide per source whether direct integration (HealthKit, Health Connect, BLE/GATT) or an aggregator (Validic, Terra) is the right trade-off, then model everything to FHIR R4 so the data is portable across care, analytics, and billing.
How does wearable data reach your app?
See how HealthKit, Health Connect, BLE, and Validic feeds converge into a normalized, consent-aware FHIR data layer.
What do we integrate?
Consumer platforms, clinical BLE devices, and aggregators, normalized into one canonical, consented data layer.
Apple HealthKit
Background delivery, anchored queries, and workout/vitals sampling from Apple Watch and iPhone, with explicit per-type read permissions and correct unit handling for heart rate, HRV, SpO2, and activity.
Android Health Connect
Unified reads across Fitbit, Samsung Health, and Google Fit through Health Connect's permission model, replacing the deprecated Google Fit APIs with change tokens for incremental sync.
Bluetooth Low Energy (BLE) devices
Direct BLE/GATT connectivity for blood pressure cuffs, pulse oximeters, weight scales, and glucometers using standard health profiles, plus vendor-specific characteristics where needed.
Validic & aggregator coverage
Validic and Terra integrations for hundreds of consumer and clinical devices through one API, cutting the per-device maintenance burden when broad coverage matters more than direct control.
Consent-aware FHIR pipeline
Every reading normalized to FHIR R4 Observation with unit conversion, de-duplication, and a consent record, so PHI is captured, scoped, and auditable from the device to the chart.

Our Process
How do we ship a wearable integration?
We treat data quality and consent as first-class from day one, so the stream is clinically trustworthy, not just present.
1.
Source & data-model discovery
We inventory target devices and platforms (HealthKit, Health Connect, BLE, Validic) map their data types and units, and define the canonical FHIR Observation model.
Canonical model
2.
Connectivity & permissions
Platform permission flows, BLE pairing and GATT handling, and aggregator onboarding, with consent capture wired into each source.
Consent captured
3.
Normalization & sync
Unit conversion, de-duplication, gap and backfill handling, and incremental sync tokens so the data layer stays clean under real-world device behavior.
Clean data
4.
Delivery & monitoring
FHIR write-back, downstream event hooks for care and billing, and observability on sync health and device drop-off.
Observable
Evaluation criteria
How do you evaluate a wearable data source?
Evaluate a wearable data source on regulatory status, data granularity, sync path, history, update signal, consent handling and BAA terms. Ask each device maker or SDK the questions below; the answers decide whether you connect directly, through the phone's health store or via an aggregator.
| Criterion | What to find out | Question to ask |
|---|---|---|
| FDA status | Whether the device is marketed as a general wellness product or is an FDA cleared or approved medical device | Is this measurement cleared for the clinical use we plan, and under which intended use? |
| Data granularity | Individual readings with timestamps, or only daily summaries | Can we get each reading with its time and unit, or only daily totals and averages? |
| Sync path | Whether data reaches you through the on-device store (HealthKit or Health Connect), the vendor's cloud API, or both | Which path carries the complete data set, and does either one drop data types? |
| Historical backfill | How far back data can be pulled when a patient first connects | How much history can we request on first connection, and at what granularity? |
| Push or polling | Whether the source sends webhooks when new data arrives or must be polled | Do you send webhooks, and if not, what polling limits apply? |
| Consent revocation | What happens when the patient disconnects the device or withdraws permission | Are we notified when a user revokes access, and what happens to data already shared? |
| BAA for the vendor cloud | Whether the vendor will sign a business associate agreement when its cloud holds PHI for you | Will you sign a BAA for this use, and which of your services does it cover? |
We do not rank vendors. The same device can be the right choice for an engagement feature and the wrong one for data that drives care decisions.

Frequently Asked Questions
Yes. When device data is PHI, Agnotic signs a business associate agreement before any PHI is shared with our team, and we keep PHI out of development and test environments.
The number of sources and the depth of normalization, more than the app itself. One platform, such as HealthKit or Health Connect, is the usual first release; BLE devices and an aggregator add scope. We scope it on the scoping call.
It depends on the sources. A first source with a clean FHIR data model comes first; BLE devices, a second platform or aggregator coverage are phased on top. Direct BLE work takes longer than aggregator integration because each device needs its own handling.
Use direct APIs and BLE when you need tight control, low latency, or a small device set. Use an aggregator like Validic or Terra when broad multi-vendor coverage matters more than direct control and you want to cut per-device maintenance. We frequently combine both in one platform.
We normalize every reading to FHIR R4 Observation with LOINC coding, then write it back to your EHR or FHIR data layer. Because the model is standards-based, the same stream also feeds analytics and RPM/RTM billing without a second integration.
Yes. We build HealthKit background delivery and anchored queries on iOS, and Health Connect with change tokens on Android, including the migration off the deprecated Google Fit APIs. We keep the permission and data model consistent across both platforms.
We capture per-source consent, scope permissions to the minimum data types needed, encrypt in transit and at rest, and log access. PHI is handled the same whether it originates from a consumer wearable or a clinical BLE device.
It depends on the device and the measurement. We check whether a reading comes from an FDA cleared device or a product marketed for general wellness, then agree with your clinical lead which readings can drive care decisions and which are shown as context only.
Yes. We scope the first release to one workflow, such as Apple HealthKit or Health Connect step and heart rate data flowing into your platform as FHIR Observations. More sources, an aggregator and EHR write-back follow once that stream is clean.
AI tools help our engineers draft code and tests, but a person reviews every change, and it passes the same automated tests and security checks as any other code, including tests for duplicate samples and unit mismatches. Which tools may see your code or data is agreed with you at the start.
