The Google Fit API Migration Imperative

Critical deadline: Google Fit APIs stop working June 30, 2025. Android apps using Fit must migrate to Health Connect or lose all wearable functionality completely.

This isn't a simple API swap, it's an architectural change affecting:

• Permission models and user consent flows
• Data schemas and query patterns
• Background sync and battery optimization
• Manufacturer-specific Health Connect implementations

Apps using Fit APIs after the deadline break completely, losing access to steps, heart rate, sleep, and all health metrics. Experienced wearables development companies understand Android fragmentation and manufacturer variations in Health Connect adoption.

What this means for your project:

• Budget migration work into 2025 roadmaps
• Test across multiple Android manufacturers (Samsung, Google, OnePlus)
• Update privacy policies and user consent mechanisms
• Verify data continuity during migration for existing users

Wearable Data Integration: Beyond Simple API Calls

Professional wearable integration encompasses far more than connecting to HealthKit:

Data Normalization Challenges

Raw wearable data arrives in inconsistent formats. Heart rate from Apple Watch uses different structures than Garmin or Whoop. Without normalization, devices can't be compared, clinical algorithms break when users switch devices, AI models fail across vendors, and EHR integration becomes impossible.

Multi-Device Support

Users don't stick with one wearable forever. Your health platform must handle:

• Device switching mid-program without data loss
• Simultaneous data from multiple devices (fitness tracker + CGM)
• Historical data migration when users upgrade devices
• Graceful degradation when specific metrics unavailable

Clinical Context

Consumer wearable data requires clinical interpretation:

• Sleep "score" doesn't map directly to clinical sleep disorders
• Heart rate variability needs context (resting vs. active, time of day)
• Step counts require adjustment for gait impairments
• Calorie estimates vary 20-30% between devices

Infrastructure Requirements

Production wearable platforms need:

• Real-time data ingestion pipelines handling millions of daily data points
• HIPAA-compliant storage with audit logging and encryption
• Anomaly detection flagging device errors vs. clinical events
• Offline-first mobile architecture synchronizing when connectivity restored

Conclusion: Infrastructure, Not Features

Wearable integration in 2025 is infrastructure work, not feature development. The companies worth partnering with understand data pipelines, normalization challenges, clinical context, regulatory requirements, and operational realities of maintaining wearable-connected systems at scale.

This list prioritizes delivery competence over marketing claims. We selected partners who've shipped production systems, navigated regulatory pathways, and built infrastructure that stands up under real-world use.

Whether you're a startup validating product-market fit or an enterprise deploying at scale, one of these seven companies offers genuine capability in mobile health app development and wearable data integration that goes beyond basic API calls.

The landscape keeps evolving with Google Fit sunsetting, proprietary device proliferation, AI integration opportunities, and regulatory changes mean wearable integration requirements will look different in 2026 than today. The best partners are already building for that future, contributing to open-source infrastructure, publishing technical guides, and treating wearable integration as the strategic architectural decision it is.
