Wearable App Development Services
We build wearable integrations and health apps across the full device ecosystem. Every solution ships with real-time data normalization, HIPAA-compliant storage, and the interoperability layer needed to connect wearable data to clinical systems.
Wearable Device Integration
Native SDK integrations for Garmin, Apple Watch, Whoop, Polar, Suunto, Samsung, and Google Health Connect. Unified data pipeline that normalizes metrics across providers into a single, queryable health data model.
Health & Fitness Mobile Apps
Consumer and clinical mobile apps for iOS and Android that connect to wearables, display real-time metrics, and surface actionable health insights. Built with HIPAA-compliant data handling from day one.
Clinical Wearable Platforms
Remote patient monitoring platforms that pull wearable data into clinical dashboards. Clinician-facing tools with alert thresholds, trend analysis, and EHR integration for care teams managing chronic conditions.
Health Data Analytics
Analytics layers on top of multi-device health data. Population health dashboards, individual score computation, and AI-ready data structures for predictive health insights and personalized recommendations.
FHIR & Interoperability Layer
FHIR R4 mapping for wearable data — exposing device metrics as standardized FHIR Observations. Enables wearable data to flow directly into EHRs, payer systems, and clinical research platforms.
Why Healthcare Companies Choose Momentum for Wearable Development
We Built Open Wearables
We don't just integrate wearables — we built Open Wearables, an open-source platform that solves multi-provider data normalization at scale. We understand the SDK edge cases, OAuth flows, and data gaps that generalist agencies learn on your project.
HIPAA from the First Commit
Wearable health data is PHI. We architect encryption, access control, and audit logging before writing business logic — not as a compliance phase at the end. Every project ships ready for BAA signing and security questionnaires.
AI-Ready Data Architecture
We model wearable data for AI from the start. Normalized time-series, FHIR-mapped observations, and structured feature stores that support predictive analytics, anomaly detection, and personalized health scoring without retrofitting.
Multi-Provider Without the Chaos
Supporting 10+ wearable providers means managing 10+ different APIs, auth flows, data schemas, and sync cadences. We've built the abstraction layer that makes multi-provider support maintainable — so adding a new device doesn't mean rewriting your data pipeline.
Our Wearable Technology Stack
We pick the stack based on your device ecosystem and clinical requirements. SDK support, data frequency, battery constraints, and interoperability needs drive every technology choice.

Responsive patient portals and clinical interfaces
Backend & APIs
Secure, scalable medical web app architecture
Database & Storage
Healthcare-specific encryption and audit logging

Security & Compliance
Advanced encryption, OAuth 2.0, and compliant infrasctructure
Healthcare Web Platforms We've Delivered
Fitness-to-Insurance Rewards App With Multi-Device Wearables Integration
Steppie needed to translate everyday physical activity into real insurance savings, which meant wearable data accurate enough for an insurer to trust. We built the platform on Google Fit and HealthKit integration with precise activity tracking and a gamified reward system connecting movement to premium reductions.
ML-Powered Health Monitoring With Wearable Data for Senior Patients
ZdroVeno needed seniors to notice a health problem before it became an emergency, using data most wearables already collect but nobody was analyzing in real time. We built an ML-powered engine processing Google Fit and Apple Health data through a sub-300ms pipeline, detecting HRV anomalies and triggering intelligent caregiver alerts.
On-Demand Fitness Platform With Cross-Platform Wearables Connectivity
Amino needed to connect users with personal trainers through a mobile booking flow that felt as easy as fitness apps people already used daily. We built native apps on a Ruby on Rails backend with cross-platform wearable connectivity, reaching 5,000+ downloads and 250 registered trainers within the first year.
Our process
From first call to production launch
A clear, structured path from discovery to a compliant, scalable wearable integration — with visibility at every stage.
Discovery
We map your device ecosystem, data needs, and compliance requirements before writing a single line of code.
Architecture
We design the data pipeline and integration layer for your specific device stack.
Integration
We connect devices and normalize incoming health data in real time.
Compliance validation
We verify HIPAA, GDPR, and FHIR alignment before anything ships to production.
Launch & support
We deploy to production and stay on to monitor, scale, and iterate.
Proof by numbers
Results that matter
90,000 active users
get a complete picture of their health through one wearables integration.
7+ wearable providers
supported through a single, normalized data pipeline.
HIPAA & GDPR compliant
from the first commit, with FHIR-native data mapping.
Supported devices
One integration, every major wearable
We connect to the wearable ecosystem your users already wear — normalizing data from every provider into a single, consistent model your product can rely on.
Frequently asked questions
Which wearable devices and platforms do you support?
We integrate with Garmin, Apple Watch, Whoop, Polar, Suunto, Samsung Health, and Google Health Connect, among others. If your users wear a specific device we haven't listed, we can typically add support for it during discovery.
How long does a typical wearable integration take?
A single-provider integration typically takes 4–6 weeks from discovery to launch. Multi-provider integrations with clinical-grade compliance requirements usually take 8–12 weeks, depending on scope.
Is our data handled in a HIPAA and GDPR-compliant way?
Yes. We architect encryption, access control, and audit logging from the first commit — not as a compliance step at the end. Every project ships ready for BAA signing and security questionnaires.
Can you integrate wearables into our existing product?
Yes. Most of our wearable projects add integration to an existing mobile or web app rather than starting from scratch. We assess your current architecture during discovery and design the integration layer to fit it.
Do you support FHIR and EHR interoperability?
Yes. We map wearable data to FHIR R4 Observations, enabling it to flow into EHRs, payer systems, and clinical research platforms alongside the rest of a patient's record.
