BUILT ON OPEN SOURCE

We built Open Wearables. An open-source wearable data platform.

Open Wearables is an open-source wearable data platform we built and maintain. It connects to multiple wearable providers, ingests health data, and computes scores using algorithms our team designed from scratch. Not licensed from a third party. Not a black box. When you work with us on wearables integrations or custom features, you work with the team that built the platform.

Wearables Projects 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. The result works for both sides: lower claim rates for insurers, real rewards for the people generating the data.

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 before a family member would otherwise know something was wrong.

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, with payments and wearable data working the same way across iOS and Android. We built native apps on a Ruby on Rails backend with PayFort and Apple Pay integration and cross-platform wearable connectivity, reaching 5,000+ downloads and 250 registered trainers within the first year.

Wearables Integration Frequently Asked Questions

What devices do you support for wearable app development?

Open Wearables natively supports Garmin, Apple Health, Oura, Whoop, Polar, Suunto, Samsung Health Connect, and more. Apple watch health app data flows through Apple Health integration, and fitbit integration is on the roadmap. For devices not yet in Open Wearables, we build custom integrations and connect them to the same unified API. Your app gets a single normalized data model regardless of which wearables your users connect.

How does Open Wearables compare to SaaS wearable platforms like Terra or Junction?

Open Wearables is self-hosted and MIT-licensed. Your only ongoing cost is your own infrastructure and the operations time to run it, not usage-based pricing that scales against your growth. No vendor lock-in, and the cost depends on your data retention policy, data volume, and hosting setup rather than your user count.

Can you build a health tracking app with custom health scores and metrics?

Yes. We build custom health scores from wearable data: HRV analysis, sleep quality scoring, activity pattern recognition, and risk stratification algorithms. These metrics are tailored to your patient population and clinical goals, not generic calculations.

How do you handle apple health api connectivity and other device integrations?

Through Open Wearables' provider system or custom integrations depending on your needs. Each device has its own OAuth flow, data schema, and sync strategy. We normalize everything into a unified data model so your application code works the same regardless of which wearable your users connect.

What is your experience with remote patient monitoring app development?

We have built remote monitoring systems that connect wearable devices to clinical dashboards with threshold-based alerts, caregiver notifications, and FHIR-compliant data export. ZdroVeno is our reference project: ML-powered health monitoring for seniors with anomaly detection and sub-300ms data processing.

Can you integrate wearable data with our existing EHR or clinical system?

Yes. We connect wearable data pipelines to EHR systems through FHIR and HL7 interfaces. Our FHIR MCP Server enables natural language queries against clinical data, and normalized wearable output maps directly to FHIR-compliant resources.

How does wearable technology healthcare integration handle data privacy?

HIPAA-compliant architecture from day one. Open Wearables is self-hosted so patient data stays on your infrastructure. Encryption at rest and in transit, audit logging, and access controls designed for protected health information. No third-party SaaS platform handling your patients' wearable data.

Do you build fitness app development projects with gamification?

Yes. Steppie is our reference project: a fitness-to-insurance rewards app with gamified engagement, precise activity tracking, and multi-device wearables connectivity. We build reward systems, challenges, leaderboards, and achievement mechanics tied to real wearable data.

Can you build AI features on top of wearable data?

We build the full stack from wearable integration to AI: data normalization, feature extraction, ML model training, and production deployment. Health scores, anomaly detection, predictive analytics, and personalized recommendations built on your wearable data pipelines.

How long does a typical wearables integration project take?

It depends on scope. A single-device integration with basic data display can ship in weeks. A multi-device platform with custom health scores, AI features, and clinical system integration is a larger engagement. We scope every project based on your device requirements, data needs, and product goals.

Do you offer wearable app development services as a standalone engagement, or only as part of a bigger build?

Standalone. Some clients need device integration added to an existing app without a full platform rebuild around it.

How is your wearable app development different from other wearable app development companies?

Most integrate against someone else's API. We wrote Open Wearables ourselves, so when a device vendor changes something, we fix it at the source instead of waiting on a third-party SaaS provider to patch it.

Do you build healthcare wearable app development projects specifically, or consumer fitness apps too?

Both, often on the same underlying data pipeline. A consumer fitness app and a clinical remote monitoring tool can share the same normalized wearable data model, just with different compliance and alerting layers on top.

Do you offer android wearable app development, or mostly iOS and Apple Watch?

Both, equally. Wear OS and Android-connected devices get the same normalization and sync reliability testing as Apple Health and watchOS integrations.

Are you a wearable app development company based in the USA?

We're headquartered in Wroclaw, Poland, and work with clients across the US and 20+ other countries. English-first communication and time zone overlap are built into how every engagement runs.

Do you work with wearable app development companies as a subcontractor, or only direct clients?

Direct clients mostly, though we've supported agency partners who needed wearable-specific expertise they didn't have in-house for a single project.

What happens if a wearable vendor changes their API after our app is already live?

We monitor provider API changes as part of ongoing support and update the Open Wearables integration before it breaks in your production app, the advantage of the same team maintaining both the standard and your implementation.

Can you migrate us off a SaaS wearable API like Terra or Vital onto Open Wearables?

Yes. Migrations typically run alongside your existing integration until data parity is confirmed, then cut over without an interruption your users would notice.
