The challenge
MediCare's previous vendor had delivered a React Native app that failed HIPAA audit on PHI storage — patient records were persisting in AsyncStorage in plaintext. The app also had no offline mode, and video quality was unusable on anything below LTE. They needed a rebuild with a clean compliance posture before their CMS contract renewal deadline.
Our approach
We rebuilt the app in React Native with encrypted SQLite (SQLCipher) for local storage, Twilio Programmable Video for E2E-encrypted calls, and Stripe for in-app payment processing. All PHI is encrypted at rest and in transit. A BAA was in place before the first line of code was written. The app passed HIPAA technical safeguards audit on first submission.
Results & impact
The app hit 100K active users within four months of launch. Video consultation volume runs at 50K sessions per month with average connection quality rated 4.3/5 by patients. The app holds a 4.8-star rating across both stores.
What we delivered
React Native App (iOS + Android)
Native-quality experience with SQLCipher-encrypted local storage and offline appointment access.
E2E-Encrypted Video Layer
Twilio Programmable Video integration with adaptive bitrate and in-call recording for provider notes.
HIPAA Compliance Package
Technical safeguards implementation, BAA template, and audit-ready documentation.
In-App Scheduling & Billing
Calendar sync with provider availability, Stripe payment processing, and automated receipts.

Our previous vendor left us with a compliance liability. ArrayMatic not only fixed it — they made our engineering team understand why it mattered. We haven't had a compliance flag since.
