LowLight

A sleep and wellness app that helps turn evenings into moments of calm.

Concept

LowLight is a mobile app designed to help stressed young professionals protect their personal time and get better rest. By connecting their schedule with personalized wind-down routines, LowLight turns rest into an intentional part of the day rather than something left over after everything else is done.

Problem Statement

Young professionals in their mid-twenties to thirties reclaim nighttime as their only personal time after work. This results in intentionally delaying sleep despite fatigue, leading to a cycle of sleep deprivation and a loss of control over their time and well-being.

Interviews & Empathy Map

Understanding why.

Across different lifestyles and routines, the same themes appeared again and again:

Stress is the primary barrier.

Work anxiety, unresolved thoughts, and mental overstimulation were the most common causes of poor sleep.

Existing solutions lack consistency.

Participants had experimented with supplements, sleep aids, and routines, but most struggled to maintain them over time.

Sleep is valued but rarely protected.

Every participant used their phone before sleeping and expressed frustration about the habit.

Interviews & Empathy Map

Empathizing.

To better understand users' relationship with sleep, I conducted interviews and synthesized the conversations into empathy maps. My goal was to understand where the poor sleep was coming from holistically, rather than thinking of it as an isolated issue.

This helped uncover recurring behaviors, frustrations, and unmet needs that would later inform the product direction.

Exploration

competitive analysis

I analyzed existing sleep, wellness, and productivity apps to understand how they approached relaxation, habit-building, and nighttime routines. This helped me identify gaps and opportunities for LowLight to offer a more intentional way to wind down.

Sketches & Storyboard

Exploring Solutions

The storyboard helped me think beyond individual screens and map out the experience in a more emotional, human perspective. I explored information architecture, user flows, and core functionality through low fidelity sketching before moving into digital wireframes.

Usability Testing

Refining the Experience.

With the initial prototype in place, I conducted usability testing to see how easily participants could navigate LowLight's core features and complete key tasks.

Testing revealed several areas where the interface didn't communicate hierarchy or navigation clearly enough. I used these findings to refine the information architecture and make important actions easier to discover.

bringing it to life

I focused on establishing a clear hierarchy across LowLight's main features; including wind-down routines, sleep content, mood tracking, planning, and Mood Buddy.

Moodboard

calming, modern, serene.

LowLight’s visual direction was inspired by soft lighting, nature, and dark, calming environments to create an experience that feels serene, removed from the hectic pace of everyday life.

Logo Design

From sketch to symbol

Drawing from my moodboard, I started by making rough sketches of geometric shapes. I was interested in exploring negative space, connecting shapes, and using overlap to create abstract pieces that felt spontaneous yet grounded. I wanted the forms to feel balanced without being too rigid. I created a shape inspired by both a crescent moon and a lamp, referencing the idea of low, soft light and winding down. This became the foundation for the logo.

For the final icon and logo, I settled on a dark gray with subtle muted purple undertones, paired with subtly glowing text that evokes the feeling of soft light in the dark.

Final Design

designed around real habits

LowLight was designed around behaviors participants were already doing rather than idealized routines they were unlikely to maintain. The goal was to make winding down feel easy enough to return to every night.

Final Design

wind down

Wind Down gives users a dedicated moment to pause, reset, and prepare for rest.

A personalized routine that adapts to how you’re feeling and what you need that night.

Simple activities like journaling, breathing, and calming audio to help create a natural transition into sleep.

Designed to feel like a valued part of the nighttime routine; a tool that gives people permission to slow down.

Final Design

onboarding

Onboarding establishes the app as a personalized space for winding down. Users share their preferences and goals so LowLight can better understand what helps them relax.
