Healthcare App Development Cost: The Real Numbers

What a healthcare app actually costs: three honest bands

Across 2,000-plus projects delivered at Digital Heroes, healthcare builds cluster into three bands. The band you land in is decided by three things: how many external systems you touch, whether real patient data flows through the app, and how many user roles need their own screens.

Band 1: Patient-facing MVP, $55,000 to $85,000, 12 to 16 weeks

This buys one platform (React Native for iOS and Android, or a responsive web app), one user role, and roughly 20 to 28 screens. Typical scope: secure sign-up, profile and medical history intake, appointment booking against a calendar you own, reminders, document upload, and in-app messaging that is asynchronous, not live. Team: one product designer part-time, two full-stack engineers, a QA engineer at half allocation, a delivery lead at a quarter.

What falls out at this price, and you should hear this clearly: no EHR or Health Level Seven (HL7) integration, no live video, no insurance eligibility checks, no clinician-side admin console beyond a basic table view, no formal HIPAA audit package, no data migration from a legacy system, and no offline mode. If a vendor quotes $60,000 and the word "integration" appears in the scope, one of you has misunderstood the job.

Band 2: Compliant, integrated product, $110,000 to $180,000, 5 to 7 months

Here you get two or three roles (patient, clinician, admin), 40 to 60 screens, and the compliance work treated as engineering rather than a checkbox: encryption at rest and in transit, role-based access control, full audit logging on every read and write of Protected Health Information (PHI), session timeouts, Business Associate Agreements with each subprocessor, and a written security policy set. One real integration is included, usually Electronic Health Record read and write via Fast Healthcare Interoperability Resources (FHIR), or a lab results feed, or a payments and eligibility check. Native iOS and Android instead of a single cross-platform build sits at the top of this band.

Band 3: Clinical platform, $180,000 to $300,000, 7 to 11 months

Four or more roles, 80-plus screens, live telehealth video with waiting rooms and session recording, e-prescribing or claims, two to four integrations, a reporting layer clinicians will actually open, and data migration from whatever the practice runs today. Team grows to six or seven: two backend, two frontend or mobile, a designer, a dedicated QA, a DevOps engineer part-time, plus a delivery lead. Above $300,000 you are usually buying either multi-tenancy for many clinics or a regulated medical device claim, and the second one is a different conversation with a different budget.

What actually drives the number

Six variables move healthcare budgets. Every one of them has a price.

1. Integration count, $12,000 to $35,000 each. This is the single biggest swing factor. A clean FHIR read against a modern sandbox costs about $12,000 to $18,000. A legacy HL7 v2 interface, a vendor with a six-week credentialing queue, or an on-premise system reachable only through a Virtual Private Network costs $25,000 to $35,000 and adds calendar weeks you cannot compress with more engineers. Three integrations is not three times one integration, it is closer to 3.5x because each one brings its own sandbox, its own certification, and its own failure modes to handle.

2. Compliance depth, plus 18 to 30 percent on the build. "HIPAA compliant" is not a library you install. It is audit logging on every PHI touch, key management, access reviews, encrypted backups, incident response runbooks, staff training records, and BAAs with your cloud and every vendor in the path. On a $120,000 build that adds $22,000 to $36,000. A SOC 2 Type II report on top is a separate $25,000 to $50,000 across audit fees, tooling and roughly 60 engineering hours of evidence work. If you need General Data Protection Regulation coverage for European users too, add a further 5 to 8 percent for consent, residency and deletion flows.

3. Data migration, $8,000 to $40,000. Cost tracks record count and source quality, not ambition. A clean CSV export of 5,000 patients: about $8,000. A 15-year practice management database with duplicate patients, free-text fields where structured data should be, and no reliable unique identifier: $30,000 to $40,000, most of it spent on reconciliation and dry runs rather than on the script itself. Ask for the export before you sign the contract. The state of that file predicts your number better than any conversation.

4. Mobile plus web, plus 40 to 60 percent over one platform. React Native or Flutter sharing one codebase across iOS and Android adds about 25 to 35 percent over a single mobile target. Two fully native apps plus a web portal adds 60 to 80 percent, because you are buying three test matrices and three release trains. Choose native only if you need deep device features such as Bluetooth medical peripherals or background health data sync. Otherwise you are paying a real premium for a difference most patients will not perceive.

5. Design depth, $8,000 to $45,000. Applying an existing design system to 25 screens: $8,000 to $12,000. Original UX with clinician workflow research, prototypes and two usability rounds: $30,000 to $45,000. Clinical screens that fight the user cause charting errors and abandonment, and redesigning them after launch costs more than doing the research first.

6. Real-time and offline, $15,000 to $45,000. Telehealth video built on a managed provider such as Twilio or Agora costs $15,000 to $25,000 in engineering plus per-minute usage. Building signalling yourself doubles that and buys you nothing. Offline-first with conflict resolution for field clinicians is $25,000 to $45,000, because sync conflicts on medical records demand deliberate merge rules, not last-write-wins.

Worked example: telehealth and scheduling platform for a 12-clinician group

Patient mobile app on React Native, clinician web console, live video, EHR appointment sync, HIPAA controls, migration of 9,000 patient records.

• Discovery, workflow mapping, technical architecture, 3 weeks: $11,000
• UX and UI design, 46 screens across two roles, one usability round: $24,000
• Patient app: onboarding, booking, reminders, intake forms, documents, 10 weeks: $38,000
• Clinician console: schedule, patient records, notes, video launch, 8 weeks: $32,000
• Backend, application programming interface, roles and permissions, notifications: $29,000
• Telehealth video integration on a managed provider: $19,000
• EHR appointment read and write via FHIR, including sandbox certification: $21,000
• HIPAA engineering: audit logs, encryption, access control, key management, policy set: $26,000
• Data migration, 9,000 records, three dry runs plus reconciliation: $16,000
• Quality assurance, security testing, penetration test coordination: $18,000
• DevOps, environments, monitoring, backups, disaster recovery: $11,000
• Project management across 6.5 months: $17,000
• Subtotal: $262,000
• Contingency at 10 percent: $26,000

Total: $288,000 over 6.5 months. Strip the video and the EHR sync and the base drops to $222,000, or $244,000 with contingency. Strip the clinician console and half the design surface on top of that and you ship patients-first at $196,000, which is how most groups should actually start. That contingency line is not padding. On most of the healthcare projects we run, the EHR vendor's sandbox behaves differently from production, and the fix lands somewhere in that 10 percent.

The ongoing costs nobody quotes

Budget year one at 30 to 50 percent of the build, every year, indefinitely. On the $288,000 example that is roughly $85,000 to $145,000.

Hosting and infrastructure: $600 to $3,500 a month. A HIPAA-eligible AWS or Google Cloud setup with encrypted managed database, redundancy and log retention starts near $600 for a small user base and reaches $3,500 by 20,000 active patients. Signing a BAA with either provider is free; the architecture it obliges is not.

Third-party services: $400 to $2,500 a month. Video minutes, SMS reminders through a provider like Twilio at published per-message rates, transactional email, error monitoring, and an EHR vendor's own API or marketplace fee, which some charge per practice per month.

Maintenance: 15 to 20 percent of build cost per year. On the $288,000 build above that is $43,000 to $58,000 annually. It covers iOS and Android release compatibility twice a year, dependency and security patching, EHR API version changes you do not control, and bugs found in production. Skip it for a year and the catch-up costs about double, because the upgrades compound.

Year one change requests: $20,000 to $50,000. Every healthcare client discovers real workflow only after clinicians use the thing. Reserve for it. Clients who budget zero here end up freezing a product that is 80 percent right, which is the worst outcome available.

Annual compliance: $8,000 to $30,000. Penetration test, access reviews, policy refresh, and a SOC 2 renewal audit if you carry one.

How to not get burned on price

The cheapest quote is usually the least specific one, and specificity is the whole job. When a $45,000 bid sits next to a $140,000 bid for the same brief, the gap is almost never developer skill. It is that the cheap quote excluded compliance engineering, assumed the EHR integration is a weekend, priced one platform while you asked for two, and carried no QA line. That work does not disappear. It arrives as change orders at 1.5x the rate you would have paid to scope it upfront, or it arrives as a breach. We have rescued enough of these to price the pattern: a healthcare rebuild after a failed cheap build runs 60 to 90 percent of a fresh project, and you have already spent the first budget.

What a change request should cost. A fair blended rate, an estimate in hours before work starts, and no minimum block larger than four hours. A small change to an existing screen should be $400 to $1,200. A new screen with backend support should be $2,500 to $6,000. If every request comes back as "two weeks, $15,000," the scope was never understood.

Contract terms that protect the number. Fixed scope with a written change process, not fixed price on a vague brief, which just moves the fight to the definition of "done." Intellectual property transferring on payment of each invoice, not at final delivery, so a dispute never holds your product hostage. Source code committed to your repository from day one, with your organization owning it and the vendor holding access, so you can see progress weekly and switch teams if you must. Infrastructure in your cloud account, under your billing. A signed BAA before any real data exists. A named team, so the senior engineer in the pitch is the one who writes the code.

How to brief a vendor so the quotes are comparable

Send the same six things to every vendor and the spread between quotes collapses from 3x to about 1.3x.

One: the user roles, named, with what each can see and do. Two: every external system by name and version, plus whether you already have sandbox credentials. Three: your compliance target stated exactly, HIPAA alone, HIPAA plus SOC 2, plus GDPR, and whether an auditor is already engaged. Four: the platforms, and whether cross-platform is acceptable. Five: the data to migrate, with a row count and a sample export attached. Six: the launch date and what is driving it, since a real regulatory or contractual deadline changes team shape and price, and an aspirational one should not.

Then ask each vendor for the same three artifacts: a line-item estimate with hours per feature, an explicit exclusions list, and two references who launched a healthcare product with them and are still running it. The exclusions list tells you more than the total. A vendor who cannot write down what they are not building has not thought about what they are.

If you would rather scope this before committing budget, Digital Heroes contracts through India LLP, US LLC and UK LTD entities, so the agreement and the intellectual property assignment sit under law your own advisers already read. You can take that specification to any other firm on your shortlist.
