A UX and UI project, exploring responsive design by creating a web app for mobile and desktop. This web app, called SleepSmart, focuses on sleep health. SleepSmart is designed for individuals who struggle to get enough sleep and would like to get into a regular sleep pattern. The web app provides users with a personalised sleep or bedtime plan to meet their unique needs and goals. Unlike other sleep apps which provide one-off sleep help, SleepSmart creates a long-term plan which gradually eases users into changing their sleep routine so they can reach their goal, using exercises and activities they have selected. The three main pathways through the SleepSmart web app, accessible straight from the home page, allow users to select from the three different options – start a sleep plan, start a bedtime plan and take a sleep quiz. From these options users are guided through a range of steps to create their personalised plan.
