The Problem We Solve
Healthcare mobile apps fail not because of bad design — but because the agency building them doesn't understand PHI, clinical workflows, or what EHR integration actually requires in production.
Standard mobile developers store sensitive data in AsyncStorage or SharedPreferences — unencrypted, accessible by other apps, and a HIPAA violation waiting to be discovered.
Agencies promise EHR connectivity but can't navigate Epic's FHIR sandbox, Cerner's OAuth2 flow, or HL7 v2 message schemas — the integration becomes a perpetual backlog item.
Apple and Google have strict policies for health apps — encryption requirements, HealthKit privacy strings, health data permissions. Agencies without healthcare experience get rejected repeatedly.
↓ Peerbits replaces this with ↓
We use SQLCipher for local PHI, Keychain/Keystore for credentials, certificate pinning for API calls, and biometric authentication — HIPAA Technical Safeguards built into every component.
Our mobile integration layer ships with tested connectors for Epic, Cerner, Athenahealth, and Allscripts — including SMART on FHIR launch, token refresh, and FHIR R4 resource mapping for mobile.
We configure HealthKit entitlements, health data usage descriptions, HIPAA disclosure flows, and Google Play health policies — with a track record of first-submission approvals for healthcare apps.
What We Build
Every app type has its own clinical, regulatory, and integration profile. We've built across all of them.
Platform Strategy
The wrong platform decision costs months. We size this up in the discovery phase based on your users, data sensitivity, and device management environment.
Swift / SwiftUI for the highest-fidelity clinical UX. Best for health systems deploying on managed iPhone/iPad fleets or needing deep HealthKit / CareKit integration.
Kotlin / Jetpack Compose for Android-first deployments — ideal for payer portals, field care teams, and organizations with BYOD or ruggedized device policies.
React Native or Flutter for simultaneous iOS + Android delivery — 70–80% shared codebase without sacrificing native performance for clinical UX requirements.
Compliance Coverage
Encrypted storage, access controls, automatic logoff, audit logs, and transmission security — built into the app architecture, not bolted on.
We assess your app's SaMD classification early and design toward FDA's Mobile Medical Application guidance and Digital Health Center of Excellence criteria.
Apple App Store Review Guidelines §5.1.3 (health and medical) and Google Play's sensitive app category — we've navigated both for first-submission approval.
Accessible color contrast, dynamic type support, VoiceOver / TalkBack compatibility — required for health systems receiving federal funding.

Healthtech ,
Remote patient monitoring app helps to bridge the gap between patients and healthcare providers. It tracks the vitals of the patients and sends it to the doctors.
Healthtech , AWS / Cloud ,
A healthcare startup struggled with increasing loads of data and manual infrastructure management as its business expanded. Peerbits successfully built cloud infrastructure using AWS for their system possessing auto-scaling, automated and more.
Healthtech ,
This is a native iOS app that helps to bridge the gap between the patients and healthcare providers. Patients can monitor their health on a regular basis and share the data with the doctors and healthcare professionals.
Healthcare mobile apps must comply with HIPAA Technical Safeguards (encrypted on-device storage, access controls, audit logs), integrate with EHRs via FHIR APIs, meet FDA mHealth guidance for clinical-grade apps, pass Apple and Google's strict health data policies, and support clinical workflows that general app developers have no exposure to. A data breach on a health app can trigger fines of $100 to $1.9M per violation.
Yes. We build cross-platform apps using React Native or Flutter with a shared FHIR integration layer, while using native modules for platform-specific features like Apple HealthKit and Android Health Connect. This lets us deliver iOS and Android from a single codebase without sacrificing clinical UX quality or EHR connectivity.
It depends on the functionality. Apps that function as Software as a Medical Device (SaMD) — such as clinical decision support tools, diagnostic algorithms, or device-connected monitoring with clinical interpretation — may require FDA 510(k) clearance or De Novo authorization. Peerbits assesses your app's regulatory classification during discovery and guides you through FDA mHealth compliance pathways where required.
Yes. Peerbits integrates healthcare apps with Apple HealthKit, Apple CareKit, Google Fit, Android Health Connect, and Samsung Health — with FHIR Observation resource mapping for vitals, activity, sleep, and biometric data captured on-device or via Bluetooth medical devices.
A focused MVP — such as a patient engagement app or RPM companion app — typically takes 12–18 weeks from kickoff to App Store submission. Apps with full EHR integration, clinical decision support, BLE device pairing, or telehealth capabilities may take 6–14 months. We provide a detailed delivery roadmap after the discovery phase.
Absolutely. We offer healthcare mobile app modernization and compliance remediation — adding SQLCipher encryption to existing apps, retrofitting FHIR integration, replacing insecure local storage, implementing biometric authentication, and resolving App Store health policy violations. We start with a security and compliance audit to scope the work accurately.
