Healthcare App Development Services

Healthcare app development services cover discovery and design, iOS, Android and web engineering, EHR integration through SMART on FHIR and HL7, health data from HealthKit, Health Connect and medical devices, security and privacy engineering, accessibility, App Store and Google Play release, and ongoing support.

A focused first release usually takes three to five months from discovery to the app stores. EHR access, customer approvals, device integrations and store review often set the schedule more than coding does, which is why we start them in the first week.

Choose native Swift and Kotlin when the app depends heavily on HealthKit, Health Connect, Bluetooth devices or background processing. Choose React Native when a web team using TypeScript will maintain the app, and Flutter when you want one codebase with identical UI on both platforms. Portals and clinician tools without device features can often ship as web apps first.

Patient apps use SMART on FHIR standalone launch to read the patient's record through the EHR's FHIR R4 API after the patient signs in. Clinician apps use SMART EHR launch from inside Epic, Oracle Health or athenahealth. Writes such as appointments, questionnaires and observations use FHIR where the EHR allows it and HL7 v2 interfaces where it does not.

Yes. Apps request permission for each data type, read and write steps, heart rate, blood pressure, glucose, sleep and more, and sync them to your backend as FHIR Observations. Apple's rules forbid using HealthKit data for advertising or storing it in iCloud, and Google Fit APIs are deprecated in favor of Health Connect, so new Android apps should build on Health Connect.

Apple reviews medical apps under guideline 1.4.1 for accuracy claims and may ask for regulatory clearance documentation, and under 5.1.3 for how health data is used and consented. Google Play requires the health apps declaration and a Health Connect permission review. Both stores need accurate privacy labels and a working demo account for reviewers.

Only if a feature is a device software function. Scheduling, reminders, education, tracking and general wellness features are not regulated as devices under FDA's policy for device software functions and its January 2026 general wellness guidance. Features that diagnose, calculate doses or analyze physiological signals to drive treatment need the appropriate FDA pathway. We classify each feature during discovery.

A health app is covered when it is built for or on behalf of a covered entity such as a provider or health plan, in which case the developer signs a BAA. Consumer apps not offered for a covered entity fall under the FTC Health Breach Notification Rule and state laws such as Washington's My Health My Data Act. We design the data flows for whichever applies, and we sign BAAs.

We keep PHI out of push notifications, logs, crash reports and analytics, encrypt data on the device with keys in the Secure Enclave or Android Keystore, use short-lived tokens with biometric unlock, pin certificates for API calls, support remote wipe on managed devices and log every access to patient data on the server.

Yes. The HHS Section 504 rule requires recipients of HHS funding to make web content and mobile apps conform to WCAG 2.1 AA, from May 2026 for organizations with 15 or more employees and May 2027 for smaller ones. We test with VoiceOver, TalkBack, dynamic type and color contrast checks in every sprint.

The platforms you target, the number of EHR, device and payer integrations, whether any feature is a regulated device function, offline and real-time requirements, accessibility and language needs, and the support model after launch. Discovery produces an estimate with these assumptions written down.

Yes. We start with a code, security and store-account audit, close the gaps that put users or the release at risk, and keep shipping updates without disrupting existing users. We have taken over a live consumer health records app from earlier vendors and kept it shipping to both stores.
