MOBILE SLEEP TRACKING APP (ANDROID)
Case Study
The vast growth of advancements in Technology has pushed more and more people to incorporate them into their daily life. An industry that has faced a significant disruption due to this is the health and wellness industry. As smartphones are now much more than a phone and wearable technologies reinforce their use, healthcare-related mobile apps are becoming rapidly popular. Healthcare companies and wellness organizations one by one, adapt to this change and try to provide a variety of health-related services to the users of smartphones, tablets, or PCs.

National Wellness Institute: Elevating Membership Engagement and Growth
The National Wellness Institute is an organization founded in 1977. It offers certification and training for wellness professionals, providing them with frameworks and tools that they can use to help clients achieve their wellness goals.
Even though NWI has numerous years of experience in the wellness field, its program has been slow to catch up with technology. They have seen a substantial drop in memberships and want to find a way to add value to their members.
To do this they have decided to focus on two things:
- Create a set of digital wellness tools for Wellness coaches
- Update their image — create a new visual system that reflects their innovative and refreshed approach to wellness.
THE CHALLENGE
Despite the vast availability of personal metrics and health apps, people continue to struggle to maintain a healthy lifestyle.
We were assigned to conduct user research to understand people’s relationship with mental, physical, and emotional well-being in order to develop a tool that will drive them to action.
The National Wellness Institute wanted us to reimagine how people can adopt and maintain a routine that enhances their well-being.
- The tool could be focused on any category that relates to personal wellbeing, such as (but not limited to): exercise and fitness, eating/diet, meditation, time management, etc.
- The only requirement is that it tracks the user’s progress and pushes them to commit to a healthier lifestyle.
- The UI should reflect a fresh, updated image
an MVP Wellness App to Empower Sleep Habits and Overall Health
The app’s primary focus would be on developing an MVP solution, addressing specific wellness aspects without aiming to solve all issues.
Must-Have Features:
- User Profiles: Enable users to set up profiles with relevant information for their goals.
- Goal Tracking: Allow users to set and track their progress towards wellness goals.
- Stat Sharing: Facilitate sharing of progress stats with wellness coaches.
After conducting the market positioning of the app, our goal would be to design an app to help users analyze and improve their sleep habits, promoting better well-being.
Must-Have:
Users need to be able to set up their profile to include important information relevant to their goals
Users need to be able to set goals and track their progress
Users need to be able to share their stats with their wellness coaches
Nice to Have:
Educational component: find a way for users to stay informed throughout the process and understand why they are doing these things, and how it will affect their well-being.
Initially, we needed to do some market research so that we can identify which would be our direct and indirect competitors. We collected the most used sleep tracking apps like Sleep Cycle, Sleep++, Sleep Score, and Snore Lab, but also apps that track multiple health data like MiFit and Fitbit. After conducting Feature and Brand Analysis, we were ready to do the market positioning of our app. It seems that most apps related to sleep habits offer just one feature and that is mainly tracking sleep.
Our goal would be to design an app that would provide help to the users so that they can analyze their sleep and improve their sleep habits.
Uncovering Health related user Challenges
Our user research process involved conducting a survey and user interviews to gain valuable insights. To prepare for the survey, we utilized the Lean Survey Canvas, ensuring we asked the right questions tailored to our target audience.
The survey was sent to individuals who had used at least one health/wellness app, enabling us to gather feedback based on their experiences. This approach allowed us to uncover potential struggles, challenges, and opportunities to address with our app.
Out of the 32 respondents, the majority had downloaded 2–5 health tracking apps out of curiosity to understand their sleep patterns better. Additionally, most participants were currently using 1–2 health apps and expressed interest in sharing their health data with their healthcare providers. This valuable insight guided our design considerations.
The combination of survey findings and user interviews offered crucial insights that informed the development of our wellness app, empowering users to overcome challenges and maintain engagement in their well-being journey.
For the users, the primary motivation behind using a sleep-tracking app was to address their sleep disorders. However, they often encountered a common obstacle: losing motivation and abandoning or forgetting about the health tracking app after a short period.
Based on our User Research we could identify the user that our sleep tracking app would help. Our User Persona was Jeanine. Jeanine is a busy nature lover that wants to understand her sleep patterns but needs to have personalized sleep data to have a more realistic picture of her sleep cycles. She gets frustrated when she has started using a new app that is too complicated and she finds the apps’ reminder notifications passive-aggressive.
We needed to discover Jeanine’s struggles by following her journey when she starts using a new sleep tracking app.
In her User Journey, Jeanine wakes up and once more realizes that she woke up tired. She decided to further investigate that so she downloads a sleep tracking app. For the next two weeks, she is very happy to find every day the data of her last night’s sleep, however, it is hard for her to understand what all this means.
The days go by and a month after downloading the app Jeanine realizes that she had forgotten to check the app for more than 10 days. She tries to start using the app again but she can’t remember how it works and seems too complicated for her. Disappointed she exits the app and since she keeps waking up tired she decides to visit her doctor.
It was necessary to detect what kind of Jobs to Be Done our app could be hired to do so that we could make the right design decisions. By conducting a Value Propositions Canvas we analyzed the pains of the products that can do the needed jobs as well as their pain relievers and also the gain creators and gains generated by those jobs.
We decided to focus our design on three main Jobs To Be Done:
To develop our sleep-tracking app, we engaged in brainstorming sessions to identify essential features. Utilizing a MoSCoW map, we prioritized features based on their relevance to the Jobs To Be Done and potential value versus complexity.
For the MVP, we focused on features that would serve users’ needs effectively. Data visualization, goal setting, heartbeat data, doctor chat, data export, and notification tips were among the selected MVP features.
Our app aims to empower users to monitor their sleep, raise awareness of their sleeping habits, and ultimately enhance sleep quality
Jeanine’s Happy Flow: A Week of Using the Sleep Tracking App
By testing our Concept Sketches we finalized Jeanine’s Happy Flow after using the sleep tracking app for one week.
After waking up, Jeanine would open the app (which is also connected to her smartwatch) and she would see a Welcome screen informing her about the progress of her goal and suggesting her to her daily Journaling. Then she would go to the Journaling screen where she could add info about her last night’s sleep. Then she would move on to the Main Screen where she would find the summary of her Sleep Data so she will decide to find more details about Last night’s sleep and she will navigate to the dedicated screen. To have a more coherent picture of her sleep, she will seek the KPIs of Last Week’s sleep and she will share the data report with her doctor through the dedicated chatting screen, from where she will also send them a clarifying question about her sleep cycle.
Solving usability issues by enhancing user feedback to the prototype
We started giving life to our ideas by incorporating the user flow in a Lo-Fi Prototype for an Android sleep-tracking mobile app.
Then we started working on the first iteration of the app’s Mid-Fi Prototype which we also tested with 5 Users. The Usability Testing process provided us with very important insights and helped us understand what kind of struggles the users were facing while navigating through the prototype. Based on their feedback we adjusted some features and generated the second iteration of the Mid-Fi prototype.
According to 3 users, the Journaling screen didn’t feel intuitive or personal and they would prefer doing their sleep journaling on a screen that resembles a diary more realistically. So we decided to improve the screen by making it more personal and inviting.
Although 4 users found the app organized and clean 3 of them, expressed the need to see the sleep KPIs on the main screen in a more structured way. For them, the screen seemed overcrowded and hard to read. That is why in the second iteration we improved the data visualization by giving a better summary of the data from Last Night, Last Week, and Last Month. Jeanine could navigate to the screen quickly and inspect her sleep summary (Deep- Light Sleep, Time Awake for each night, or Average Sleep for each week or month) and if needed she could click on the details button and navigate to the page with the complete documentation.
Another screen that we found opportunities to improve was the Weekly Data screen. During the Usability Testing, the users shared with us that they would prefer observing all the types of sleep data holistically, and especially on the Weekly Sleep Data, it would be more convenient for them to find not only the sleep duration but also the heartbeat rates and the daily mood documentation. We understood that this would help not only the users to have a better picture of their sleep cycles but also their doctor in case they would like to share this data with them.
The optimized weekly data screen now included the daily sleep chart with the daily moods that Jeanine had selected along with her daily heartbeat rates. By scrolling down Jeanine would be able to detect her goal achievement and also find tips on how to improve her sleep cycle.
VISUAL DESIGN
Since the interaction design process was completed we moved on to the visual design. The app’s Brand Attributes would be Calm, Intuitive, Comfort and Motivation. Based on these attributes we composed a Moodboarad which we also tested with various users, and were happy to see that they would give the same attributes to the board.
We decided that the app should follow the moments of the day while the user would use it and it would have both a Dark and Light mode. However, since we were designing the MVP, we used the dark mode color scheme. We wanted to help Jeanine wake up gently and also easily fall asleep at night, without any intense light from her screen. With the colors, we selected we wanted to imitate the light of dawn and sunset and also to respect the eyes of the users, by providing them an accessible interface.
PROTOTYPE
The new sleep tracking app, “Zzzloth” was ready for Jeanine!
We took into consideration to also include the necessary Multistates as we wanted to provide Jeanine with an app that is intuitive, and that she doesn’t need to learn to use it again and again if she has paused its use for some time.
As soon as the Hi-Fi Prototype was ready, we conducted a Desirability testing so to understand how the users perceive the app and what feelings it causes them.
We tested the prototype with 5 users and we were glad to see that all of them were feeling that the app is clean and comforting. For most of the users, the app felt personal and made them feel happy. Everyone expressed the desire to use it and that meant that our goal was achieved.
the value of automated sleep tracking combined with opportunities for personal contribution
It was very interesting to discover that when users use a health app, they want to feel that it is more personal and not like a cold automated device. For them, it was crucial to feel that their sleep is automatically tracked and that they also have the opportunity to provide their own input. Only then they would feel that their data have value for their health.
As designers, it was a great reminder to discover that users with sleep issues need clean and organized info as this would cause them less stress. The fast pace routines usually affect them not only during the day but mainly right before their night sleep so it was crucial for them to have an app that would ease this disturbance.
The covid pandemic and the cultural differences were two factors that determined the type of communication the users have with their health providers. Users prefer to have asynchronous/distant contact with their doctor for sleep issues. “Zzzloth” sleep tracking app seemed to the users a convenient way to communicate with their doctor efficiently and the feeling that they have someone taking care of them when needed.
This was a very insightful project, during which I feel I grew a lot as a designer. It was obvious that having a thorough and solid User Research process helped us to understand the user from all perspectives. This knowledge gave us the power to compose realistic assumptions and to visually design the app in the most efficient way, which our tester users also confirmed in the end.
NEXT STEPS
Since it was a challenge for us to detect many users that not only have sleep issues but also have used a health tracking app, our next step would be to find more so that we can test the app with them and that have even more related conclusions.
Our project’s goal was to design an MVP, but since we both felt excited about this app and as we are curious designers, we would also like to design more screens for the rest of the features. That way we could further explore the rest of the opportunities available so that we can help people with sleep issues to improve their sleep quality more efficiently.
A big thank you to my colleague Arantja Rosalina. Working with her was a very enjoyable experience that helped me to grow personally and as a designer!
