LunaRest aims to support them by offering sleep guidance and fostering relaxation through an engaging and adorable user interface designed to create a sense of comfort and peace.

- Create a safe and comfortable environment through design and features.
- Provide a calming and supportive experience tailored to users’ emotional and physical needs.

Research & Users
Market Research
- The sleep monitoring app market is growing, driven by advancements in wearable technology like smartwatches.
- The growth during the forecast period can be attributed to the widespread use of smartphones, the diversification of sleep monitoring apps, the demand for apps that provide comprehensive health management, work-related stress, and an increase in corporate wellness programs.
- For example, in November 2023, data from the National Health Service, a UK-based publicly funded healthcare system, revealed that 64.9% of young people aged 17 to 23 experienced sleep problems three or more times in the previous seven nights, up from 64% in 2022. This rate remained higher than that of children aged 8 to 16 in both years. The prevalence among young women increased from 76.7% in 2022 to 74.7% in 2023, while among young men, it rose from 52.3% in 2022 to 55.7% in 2023. Consequently, the rising prevalence of sleep disorders is fueling the growth of the sleep monitor apps market.

To ensure long-term engagement, the UI was designed to be as simple as possible, removing unnecessary features while focusing on essential functionality. Recognizing that many users struggle to sleep due to stress, a meditation mode was added to promote relaxation and stress relief.
The app also includes features that allow users to monitor their sleep patterns over the long term. Users can view their average sleep duration trends daily, weekly, monthly, and annually. Since the primary target audience consists of working professionals, the app provides clear visuals of average wake-up and sleep times to help users better understand their routines.

With a UI that’s both calming and charming.
While designing the product’s logo, branding, and user interactions, I focused on creating a visually friendly and inviting atmosphere to make the app feel approachable and comforting. I created a cat illustration to evoke a sense of coziness and relaxation, enhancing the user’s emotional connection to the app.

Meditation Mode
To enhance the app’s functionality as a relaxation tool before bed, I introduced a Meditation Mode. Users can easily switch between Sleep Tracking Mode and Meditation Mode with a single button on the home screen. To clearly indicate which mode is active, the app’s background changes to reflect the selected mode, offering a seamless user experience that matches their mood.
