Automated UV Light Therapy App for a Medical Device Company

AI Healthcare IoT Engineering

BACKGROUND

About client

The client is a medical device innovator focused on developing a UV light therapy device for managing chronic skin conditions such as psoriasis, eczema, and dermatitis. These conditions affect millions of individuals worldwide, often requiring frequent clinic visits or at-home treatments. By offering a portable, targeted UV therapy device, the client aims to simplify patient care, reduce the need for lengthy hospital sessions, and ensure more consistent symptom management.

What was the client’s problem and why they reached out?
While the UV therapy device itself addressed the need for a targeted, at-home treatment, the client recognized a critical gap in how patients actually adhered to their prescribed protocols. Seeing the need for a streamlined, user-friendly solution that fully supports the at-home treatment process, the client contacted us to develop a companion app.

With a strict timeline linked to their medical device certification (CE Mark) and a launch window in early autumn, they required a rapid but compliant build - from an experienced healthcare development partner that understands both the technical and regulatory demands of medical apps.

The problems

Manual, Paper-Based Tracking

Patients relied on paper logs or simple reminders in their phone calendar, leading to missed or incorrect doses. Over time, such inconsistencies worsen outcomes or can cause skin damage.

Lack of a Seamless User Experience

The device alone solved the hardware challenge, but patients needed a convenient way to handle complex dose increments, check scheduling, and handle day-to-day therapy adjustments – all without guesswork.

Risk of Improper Usage

Incorrect or overly aggressive dose increments can cause skin burns. Patients missing sessions or arbitrarily doubling the next dose also faced potential harm. A solution that enforced guidelines and provided real-time corrective feedback was essential.

Low Patient Engagement

Without a digital companion app, the client had limited insight into how patients were actually performing treatments, making it difficult to support them proactively. Over time, the client also needed an option to expand features like photo logs or remote physician consultations.

The solutions

Treatment Tracking & Scheduling

A built-in calendar and session-logging feature where users record each treatment, mark completion, and receive automated scheduling reminders.

Impact

- Prevents missed sessions by sending timely alerts.
- Reduces reliance on manual note-keeping.
- Simplifies follow-up and adherence tracking.

Interactive Dosage Calculator

An automated tool that adjusts dose recommendations based on protocol rules (body area, skin reaction, missed sessions), preventing guesswork.

Impact
- Ensures safe, protocol-driven dose increments.
- Reduces the risk of overexposure and side effects.
- Makes treatment adjustments user-friendly.

Body-Part–Specific Protocols

A selectable interface allowing users to input the body zone, with each zone following its own dose table and protocol constraints.

Impact
- Avoids a one-size-fits-all approach that can harm sensitive areas.
- Simplifies user workflow when treating multiple zones.
- Improves treatment efficacy by matching exact protocol requirements.

Automated Reminders & Notifications

Push notifications that prompt users about upcoming treatments, missed doses, and safe intervals before dose escalation.

Impact
- Boosts adherence through timely prompts.
- Reinforces consistent treatment without overloading staff.
- Keeps patients engaged and accountable.

Patient Journal / Dashboard

A consolidated dashboard showing treatment history, upcoming sessions, skin reaction notes, and potential dose changes.

Impact
- Offers a clear ov erview of progress and any missed sessions.
- Motivates users by visualizing their adherence trends.
- Centralizes all session details in a single app view.

Tutorial & FAQ Section

A built-in help center with short videos, text explanations, safety warnings, and quick answers to common questions.

Impact
- Reduces risk of misuse by clarifying correct procedures.
- Cuts down on support calls or emails about basic usage.
- Builds user confidence in self-directed therapy.

Secure Local Data Storage (MVP)

Initially save all session logs and notes locally on the device, allowing optional manual export (e.g., PDF) without cloud retention.

Impact
- Avoids complex data privacy overhead in early stages.
- Lets patients own their own treatment records.
- Provides a roadmap for future HIPAA/GDPR-compliant expansions.
