About the Startup
A digital health startup providing an AI-driven vibroacoustic therapy app. By analyzing voice patterns in real time, it delivers personalized sound sessions to reduce stress, improve sleep, and restore balance.
The Challenge
People with PTSD often struggle to fall asleep and stay asleep. They also feel helpless and uncertain about their mental state, which worsens their distress. Accessing effective treatment is often difficult and expensive, leaving many without the help they need.

User Research & Persona
The client provided comprehensive user research data and insights from their existing user base. Based on this information, I developed a detailed user persona that guided all design decisions throughout the project
David Levi, 37, Married +2, Warehouse worker in logistics
“I feel like I can’t be the father and husband I want to be. I come home exhausted, can’t fall asleep at night – and everything just blurs together.”
Pain points
- Suffers from post-trauma that causes insomnia.
- Sleepless nights lead to severe fatigue during the day and mistakes at work.
- Financial struggles and fear of losing his job.
- Sense of guilt at home: tired, short-tempered with his kids, and less present with his wife.
Motivations
- Sleep well at night in order to function during the day.
- Reduce dependency on sleeping pills.
- Keep his job and avoid mistakes.
- Be a more patient and energetic father.
Usage Scenario
- At night, David tosses and turns in bed, feeling his heart race and tension building. He opens the app, and records his voice. The app detects a high level of anxiety and recommends a tailored treatment. After completing the session, David feels calmer and eventually falls asleep.
- In the morning, the app asks: “How did you sleep?” David rates his sleep quality, and the app logs the data, offers small tips for improvement, and displays a progress graph, encouraging him to stay consistent.
The UX Screens
My solution focuses on simplicity and immediate relief. Inspired by Shazam’s frictionless approach, I centered the experience around one key action – voice recording – that instantly assesses anxiety levels and delivers personalized treatment. The streamlined flow guides users from recording through treatment to optional calming sounds, ensuring the app remains intuitive and directly addresses users’ nighttime anxiety needs.
UI Concepts
Step 1: Establishing the Visual Language
When I presented the two design concepts to the client, he was enthusiastic about both and asked if I could create a combined style. He particularly admired the three-dimensional, standout look of the Neumorphism design and the “spacey,” nighttime feel of the Neon concept, along with its glowing purple and green colors.
Concept 1: Neon
Concept 2: Neumorphism
Step 2: Designing the Initial User Experience
Following the establishment of the visual language, the next step was to design the onboarding flow. I presented two concepts:
Concept 1 (Client's Choice): clouds and stars, emphasizing a sleep-and-night theme
Concept 2: inspired by the Northern Lights, highlighting the neon aesthetic with sound-based illustrations
Step 3: Implementing the main interface
With the core visual language and the nighttime theme established, I used these concepts to design the main interface, creating two distinct options for the main button on the homepage. The client ultimately chose Option 2, which served as our primary direction.
Option 1
Option 2 (Client's Choice)
This choice set the tone for the entire application. The final design combines neumorphic elements with a neon glow in his preferred purple and green palette, incorporating sleep elements like clouds, stars, and moon throughout the interface.
The UI Screens
