My design process for Sleepie was grounded in ease of use, personalization, and scientific backing. I began by focusing on how to seamlessly integrate the app into users' nighttime routines, so I conducted extensive wireframing and user testing. I thought it was crucial to understand individual sleep challenges, so I designed an onboarding process that includes a quick sleep assessment. Based on the user's responses, I implemented a personalization feature that provides tailored recommendations. I also wanted users to understand their sleep patterns, so I included advanced sleep tracking that monitors sleep cycles, REM phases, and circadian rhythms, and then generates detailed reports with personalized suggestions. To help users relax before sleep, I incorporated a range of guided meditation and hypnosis sessions, varying in length from 5-minute quick relaxations to 60-minute deep sleep journeys. I knew that sound was important for sleep, so I created customizable sleep soundscapes where users can mix nature sounds, white noise, calming music, and ASMR to create their ideal sleep environment. And finally, to ensure users wake up refreshed, I designed a smart alarm with a gentle wake-up mode that triggers at the optimal sleep cycle phase. Throughout the entire process, I continuously refined the user flow, making sure that each feature complements the others for a seamless and intuitive sleep-enhancing experience.
