Cross-Platform QA for a Health Monitoring Mobile Application

About Our Client

The client is a health-tech startup headquartered in Canada, focused on preventive wellness. Their mobile application enables users to monitor vital signs, track fitness goals, integrate wearables, and share health data with clinicians. With over 500,000 downloads and ambitions for FDA and HIPAA-aligned compliance, the client required flawless mobile performance across Android and iOS platforms.

Challenge

The application was evolving rapidly, but quality issues and inconsistencies threatened its user base and app store ratings:

• Sync Inconsistencies: Users reported lag or loss of health data during wearable device synchronization.
• UI/UX Gaps: App responsiveness and navigation were inconsistent across iOS and Android devices.
• Manual Testing Bottlenecks: New feature rollouts were delayed due to limited testing resources and regression overhead.
• Compliance Concerns: Ensuring adherence to HIPAA, GDPR, and Apple HealthKit integration standards was essential.
• Store Submission Issues: Frequent rejections from app stores due to crashes, privacy violations, or broken UI flows.
