VitalSync aimed to launch a mobile health platform that allows users to:

  • Track real-time biometric data
  • Connect with certified wellness coaches
  • Securely store and transmit personal health data
  • Remain HIPAA-compliant from day one
  • Scale for both iOS and Android without doubling costs

Their biggest obstacles:

  • No in-house development team
  • Tight compliance requirements
  • Urgency to launch MVP within 10 weeks
  • Needed consistent UI/UX across platforms

Solution

Elyxtech leveraged Flutter to develop a high-performance, cross-platform mobile app, reducing time-to-market without sacrificing compliance, security, or design integrity.

1. Discovery & Compliance Planning

  • Conducted workshops to understand user flows and HIPAA requirements
  • Defined core MVP features with a strong focus on security-first architecture
  • Identified and documented all required PHI (Protected Health Information) touchpoints

2. UI/UX Design for HealthTech

  • Designed mobile interfaces in Figma with accessibility (ADA) and simplicity in mind
  • Used calming visual language tailored to a wellness-oriented audience
  • Integrated onboarding for both users and health coaches

3. Flutter App Development

  • Built the app with Flutter for a single codebase across iOS and Android
  • Implemented end-to-end encryption, secure data storage, and user authentication
  • Developed modular, scalable architecture for future expansion (e.g., Apple HealthKit integration)

4. HIPAA-Compliant Infrastructure

  • Enforced secure access control and encrypted backups
  • Used HIPAA-compliant BAA cloud services (Google Cloud + Firebase)
  • Mobile-first performance and accessibility improvements

Technologies Used

Flutter (Dart)
Node.js (API)
Firebase (Firestore)
Sentry
Firebase Auth with 2FA
Firebase Crashlytics
Google Cloud (HIPAA-compliant)

Vanta (for HIPAA checklists & audits)

Results & Achievements

  • App launched in 10 weeks, ready for HIPAA-compliant pilot testing
  • Single codebase served iOS and Android users
  • Fully HIPAA-compliant infrastructure and policies in place
  • Onboarded 1,200+ early users in first 60 days
  • Partnered with 3 health clinics post-launch for data pilot integration
  • Used app demo to secure $500K in follow-on funding

This case proves that building secure, scalable, and compliant healthcare applications doesn't require months of work or massive budgets. Elyxtech used Flutter to deliver a production-grade mobile app that meets both clinical and user needs: fast, secure, and user-friendly
