Healthcare apps, built like the data in them matters

We build mobile and web products for health and wellness — from a coaching platform to an Apple Watch app that detects seizure-like motion and alerts emergency contacts — treating patient data as a design constraint from the first schema, not a policy bolted on after launch.

Why Applefy for healthcare

Health products carry a different kind of risk than most software — the data is sensitive and the stakes are real, so "good enough" security isn’t. We build for that from the first commit, and we’ve done it on both a wellness platform and a genuinely clinical use case.

01

Two real healthcare-adjacent builds

Gutfit is a wellness coaching platform we built end-to-end. Mellow is an iOS and Apple Watch app that detects motion patterns typical of motor seizures and alerts emergency contacts. One is wellness, one is a genuine medical use case — the two products we’ve actually shipped, not a broad clinical portfolio.

02

Security-minded architecture by default

Data minimization, encryption in transit and at rest, role-based access control, and audit logging are default engineering decisions on a health product for us, not a checklist bolted on before launch.

03

A compliance review as a companion service

We also run engineering-side HIPAA and GDPR gap analyses through a separate, scoped service — it maps how a product actually handles data against both regimes and hands back a prioritized fix list. It’s not a certification, because HIPAA has none to grant.

04

Native wearable and device experience

Mellow runs on iPhone and Apple Watch, reading motion sensor data to recognize seizure-like movement. We build watchOS apps more broadly too — HealthKit, workout and activity data, and sensor-driven features native to the wrist.

What we deliver

01

Patient-Data-Safe Architecture

Schema and data-flow design that minimizes what you collect and isolates what you must keep — encryption at rest and in transit, role-based access control, and audit logging built in from the first migration.

02

Device & Wearable Integration

iPhone and Apple Watch sensor data, HealthKit, and background motion or activity tracking — the same category of work behind Mellow’s seizure-detection app, built around your product’s specific signal.

03

Patient- and Client-Facing Flows

Onboarding, scheduling, coaching or care plans, progress tracking, and secure messaging — the flows a wellness or care product actually runs on.

04

Compliance-Ready Data Handling

Retention and deletion jobs, consent handling, export endpoints, and a data map you can hand to counsel — paired with our HIPAA/GDPR engineering review when you need the formal gap analysis done.

Faqs

Common questions about healthcare app development

We build with both in mind, but we want to be precise about what that means. HIPAA has no official certification, and no agency — including us — can legally declare a product "GDPR compliant"; that determination belongs to your counsel or an accredited auditor. What we actually do is build in the technical safeguards both regimes require — access control, encryption, audit logging, data minimization, retention and deletion — and offer a separate engineering gap-analysis service if you want an existing product formally reviewed against both.

The same three bands apply as any Applefy project: 3-6 weeks for a simple build ($20K-$40K), 2-4 months for a mid-complexity product ($40K-$100K), and 4-8 months for a complex build ($100K-$250K+). Healthcare products usually carry enough data-handling and integration work to land in the middle band or higher, but we scope the specific case on a call rather than guess.

Same ladder: $20K-$40K for simple projects (3-6 weeks), $40K-$100K for mid-complexity products (2-4 months), $100K-$250K+ for complex builds (4-8 months). A health product’s cost usually tracks its data architecture and compliance-review needs more than its screen count.

As the hardest part of the build, not an afterthought. That means minimizing what we collect, encrypting it in transit and at rest, enforcing role-based access control, logging who touched what, and building deletion and export paths in from the start — the same safeguards our HIPAA/GDPR review service checks for on existing products.

No — and we’d be direct with anyone who implied an app development agency could. Clinical validation and regulatory clearance (FDA, CE marking, and similar) are a specialist’s job: a regulatory consultant, a clinical research organization, or qualified counsel. Our part is building software to a standard that doesn’t get in the way of that process — reliable, well-documented, data-safe. Mellow is a good example of staying inside that lane: it alerts emergency contacts to possible seizure activity, and it doesn’t diagnose, predict every seizure, or carry a clinical clearance.

Yes — it’s some of our most directly relevant healthcare work. Mellow runs on iPhone and Apple Watch, using motion sensor data to recognize seizure-like movement and alert emergency contacts. We also build watchOS apps more generally, with HealthKit, workout and activity data, and sensor-driven features native to the wrist.
