how well did you sleep last night?
By learning about sleeping habits, it's possible to identify points of improvement in their entire life the sleep tracker app pairs with a cutting-edge sensor embedded in a pillow to help users understand their sleeping habits and improve the quality of their rest. By measuring sleep hours, movements, and interruptions through an accelerometer and presence sensor, the app provides actionable lifestyle tips for better sleep and healthier living.
Lead designer 2019
The challenge
- address the growing issue of poor sleep caused by overwork and unhealthy habits
- create a seamless integration between the sensor and the app to deliver accurate, personalized sleep insights
- ensure that the product’s measurement methodology aligns with scientific standards for credibility and effectiveness
- design an mvp to test the product vision, validate the technology, and set the foundation for future development and manufacturing
The solution
- product vision and collaboration: worked closely with the product team and developers to craft a vision for a product that doesn’t just track sleep but actively improves it through personalized feedback.
- sensor testing and algorithm refinement: conducted extensive tests with the sensor to ensure it could accurately measure sleep patterns, combining data from accelerometers and presence sensors with a robust algorithm. this iterative process helped refine the system to deliver meaningful insights.
- medical partnership: collaborated with sleep specialists to define the most valuable features and functionalities, ensuring the product could deliver benefits on par with those used in medical environments. translated these requirements into a consumer-friendly solution that tracks sleep from the comfort of home.
- intuitive app design: designed a lightweight, user-focused interface for the mvp that:
- presents sleep data in a clear, engaging, and actionable way
- delivers practical suggestions to improve sleep quality, such as bedtime routines, dietary adjustments, or relaxation techniques
- motivates users to form healthier habits through progress tracking and personalized recommendations
impact and results
the redesigned e-commerce platform successfully positioned mmartan as a leader in digital commerce for luxury linen products:
- the mvp was completed in just three months, providing a solid foundation for validating the product and refining its features for mass production.
- enabled early feedback loops by aligning the design with real user needs and scientific methodologies, ensuring both accuracy and usability.
- set the stage for a product that has the potential to improve lives by addressing a universal issue—poor sleep—through actionable, science-backed insights.
