HIPAA and BAAs
For US products involving PHI, we plan encryption, audit logging, role-based access, automatic logoff, eligible cloud services, and BAA-chain review.
HealthTech and Mental Health App Development
We build mobile apps for healthtech, mental health, and telehealth companies. From HIPAA-scoped clinical apps to AI-assisted mental health platforms, we design safety architecture and usability from the ground up.

HealthTech Products We Build
From mental health platforms and telehealth apps to clinical workflow tools and patient engagement products, we build around trust, security, and the daily reality of patients, clinicians, and care teams.
Mental health and behavioural wellness apps
Safe AI assistants, clinician handoff, crisis routing, content flows, and patient experiences that do not pretend software is a therapist.
Read AI safety guideTelehealth and virtual care apps
Video visits, async consultations, secure messaging, intake forms, prescription routing, and care-team dashboards.
Explore mobile appsHIPAA-compliant healthcare apps
Mobile products that touch PHI, with security safeguards planned from week one instead of retrofitted before launch.
Plan compliance scopeAI clinical workflow tools
Physician assistants, report review, medical documentation support, and decision-support flows with evals and human review.
Explore AI servicesPatient engagement and care coordination
Medication adherence, chronic care, post-op follow-up, reminders, secure provider messaging, and patient education flows.
Digital therapeutics direction
Mobile products positioned toward SaMD, built alongside your regulatory consultant or in-house clinical team.

Compliance Posture, Matched to Product Risk
Not every healthtech product needs the same compliance treatment. A consumer mental wellness product has a different risk profile from a telehealth platform handling PHI. We define the scope up front, then design the mobile app, backend, AI providers, cloud services, permissions, and audit trails around that scope.
GDPR and UK GDPR
For personal data and special-category health data, we support DPA workflows, data residency decisions, consent logging, and stronger field-level controls.
AI safety
Mental health and clinical AI features need crisis-detection patterns, output evaluation, memory boundaries, and human review where risk is high.
SaMD direction
For products moving toward Software as a Medical Device, we work alongside your regulatory consultant or clinical team and structure engineering around their guidance.
- /Design safety architecture into week-one decisions: crisis detection, audit trails, PHI access controls, automatic logoff, and AI output review.
- /Bring BAA, DPA, data residency, and sub-processor questions into early commercial conversations instead of waiting until procurement blocks launch.
- /Build AI mental health and clinical workflow features with human handoff, eval logging, and clear boundaries around medical advice.
- /Work with a UK and EU team that can cover product strategy, UX, mobile, backend, QA, launch support, and long-term maintenance.
/ PROCESS
How We Build HealthTech Products
A delivery process for products that need secure mobile UX, compliance-aware architecture, AI safety, integration planning, and enough clarity for clinical or investor review.
Step 1
Discovery and compliance scoping
We identify users, data sensitivity, PHI exposure, GDPR scope, AI risk, EHR needs, and the shortest credible launch path.
Step 2
Proposal with a named plan
You get scope, pricing, architecture direction, delivery team shape, and a visible compliance work plan before kickoff.
Step 3
Build and verify
Two-week sprints cover product features, QA, security-sensitive flows, integrations, and compliance milestones together.
Step 4
Launch and monitor
We support release, app-store readiness, launch checks, post-launch maintenance, and roadmap improvements from real usage.

HIPAA-Compliant Mobile App Development: 2026 Cost & Compliance Guide
Many founders realize the need for HIPAA-compliant app development only after a developer provides a quote that omits it, or when a hospital partner asks for a signed BAA before moving forward. This guide aims to help you avoid those surprises.

Frequently Asked Questions
How much does HIPAA-compliant app development cost?
HIPAA scope usually adds cost through encryption, audit logging, access controls, BAA-chain validation, documentation, and penetration testing. We define that scope during discovery so the compliance work is visible in the proposal.
Do you sign Business Associate Agreements?
Yes. For US healthtech engagements involving Protected Health Information, we discuss BAAs early and can review your form before the project moves forward.
Can you build an AI assistant for a mental health app safely?
Yes, when the product includes crisis-detection patterns, human handoff, conversation memory boundaries, output evaluation, and clinical oversight for high-risk paths. We have published a technical guide on this exact topic.
What EHR systems can you integrate with?
We can work with FHIR R4, HL7 v2, Smart on FHIR flows, and proprietary EHR APIs on a case-by-case basis depending on vendor access and your clinical workflow.
Are you GDPR-compliant for EU health data?
We operate as a Data Processor for client engagements involving personal data, sign DPAs where required, and apply stronger controls for special-category health data under GDPR Article 9.
Where is your team based?
KeyToTech has headquarters in London and an engineering delivery centre in Lviv. The team works UK and EU business hours with practical overlap for US East Coast clients.
