How Much Does It Cost to Build a Health Monitoring App Like MyChart in 2025?

Introduction

Let’s get you a realistic, no-fluff picture. You want MyChart-level functionality—medical records, appointments, secure messaging, meds, labs, billing, family access—the whole patient portal experience. That level of scope, security, and integration takes serious engineering and compliance work. The cost isn’t just about “coding an app.” It’s about building trust into every tap.

Quick answer: 2025 cost ranges at a glance

Building a healthcare app’s budget varies widely by scope, compliance, and integrations. For 2025, a basic healthcare app can start around $60,000–$100,000, while complex apps with AI, real-time features, and robust EHR integrations can exceed $300,000. Compliance, secure backend infrastructure, and UX can account for a significant share of the total budget.

Some blogs quote far lower figures—like $8,000–$25,000—but those estimates usually reflect minimal prototypes, basic feature sets, or marketing teasers rather than a production-grade MyChart alternative with rigorous security, scalability, and regulated integrations.

MVP vs standard vs enterprise-grade

• MVP: A lean patient portal (auth, profiles, appointments, basic messaging, labs via FHIR, basic notifications) to validate demand and workflows.
• Standard: Adds billing, prescriptions, advanced scheduling, provider chat, richer care plans, deeper EHR syncs, and analytics.
• Enterprise-grade: Full MyChart-like depth across multiple facilities, robust interoperability, family proxy access, accessibility at scale, incident response, SSO, and advanced observability.

A key reality check: sophisticated data handling (EHR access, interoperability), compliance (HIPAA/GDPR), and backend resilience are what push you beyond “app” territory into “health platform,” which is where the cost steps up.

What pushes costs up (or down)

• Up: EHR integrations (HL7/FHIR), multi-region cloud, SSO, advanced security, real-time video/chat, AI triage, accessibility, and performance SLAs.
• Down: Narrower scope, phased rollouts, reusing design systems, leveraging managed cloud, and focusing on one platform first.

Major cost drivers you can’t ignore

Scope and feature depth

The single biggest lever on cost is “how much” you want to ship on day one. A sharp MVP can de-risk fast; a sprawling V1 can stall budgets.

Patient portal essentials

• Authentication and identity: SSO, MFA, OAuth2/OIDC.
• Profiles and records: Demographics, consents, care teams.
• Appointments and reminders: With smart waitlists.
• Secure messaging: Provider-to-patient with audit trails.
• Notifications: Push, SMS, email across channels.

Remote care and monitoring

• Telehealth: Video visits, chat, file sharing, e-prescriptions.
• Vitals and devices: Sync data from wearables and home devices.
• Care plans: Goals, tasks, adherence tracking.
• Alerts: Clinically relevant thresholds for providers.

Family access and care coordination

• Proxy access: Parents, caregivers, and guardians.
• Permissions: Granular controls and revocation.
• Shared schedules: Cohesive planning across households.

Platforms and devices

• Mobile: iOS and Android native or cross-platform.
• Web: Patient portal for accessibility and broader reach.
• Devices: HealthKit/Google Fit, Bluetooth medical devices, tablets in clinics.

Supporting multiple platforms increases QA matrices, accessibility work, and integration complexity, which elevates cost and timelines.

Compliance and security (HIPAA/GDPR/HL7-FHIR)

Healthcare regulations are non-negotiable: HIPAA for US, GDPR for EU, and HL7/FHIR for data exchange. Implementing encrypted storage, secure APIs, access controls, audit logs, and consent management requires extra engineering and ongoing governance—this is a major cost component.

EHR and health data integrations

Connecting to EHRs and health exchanges via HL7/FHIR is table stakes for MyChart-like apps. Reliable syncing of labs, meds, allergies, visit notes, and scheduling data—plus handling edge cases and errors—adds engineering hours and QA depth, increasing budget.

Backend architecture, scalability, and uptime

You’ll need secure databases, cloud hosting, real-time processing, disaster recovery, and performance/cost monitoring. Backend infrastructure can consume 30–40% of your development budget due to security, throughput, and high availability requirements.

UI/UX design and accessibility

Accessible, intuitive UI is critical—confusing flows can cause safety issues. Research, testing with diverse users, and WCAG-compliant design often account for 15–25% of the budget, and they’re worth it for adoption and clinical safety.

Real-time features, AI, and analytics

Video consults, live chat, symptom checkers, AI triage, and operational dashboards breed complexity. Each real-time pipeline or ML feature implies new privacy reviews, data pipelines, and observability—cost multipliers beyond “standard” apps.

Team composition and location

A MyChart-like build needs product, compliance, security, mobile/web, backend, integrations, QA/automation, and DevOps. Global talent can optimize spend, but regulated healthcare demands experienced engineers and dedicated compliance processes, which increases costs.
