I wanted to design an app that combines journaling, mood tracking, and peer-to-peer support. The app would also use artificial intelligence (AI) and machine learning to predict mood based on journal entries, public posts, and mood data. Users would be able to share this data with their therapists or psychiatrists.

To understand the needs and behaviors of our target audience, I conducted a series of user interviews and focus groups. I also surveyed a larger group of potential users to gather more in-depth insights.

Through this research, I identified several key pain points and needs:

• Many users struggled with maintaining a consistent journaling practice and tracking their mood on a regular basis.
• Users wanted a way to connect with others who were struggling with similar issues and offer support to one another.
• Many users expressed a desire for more personalized, data-driven insights into their mood and well-being.

Based on my research, I designed the app to address these pain points and needs. The main features of the app included:

• A journaling feature that made it easy for users to log their thoughts, feelings, and experiences on a daily basis.
• A mood tracking feature that allowed users to record their mood on a scale of 1-10, as well as select from a list of common mood descriptors (e.g. "happy," "sad," "anxious," etc.).
• A peer-to-peer support feature that connected users with others who were struggling with similar issues and allowed them to offer support and encouragement to one another.
• An AI-powered mood prediction feature that used machine learning to analyze users' journal entries, public posts, and mood data to provide personalized insights into their mood and well-being.

I also paid close attention to the UI design, ensuring that the app was intuitive and easy to use, with clear calls to action and a logical hierarchy of information. The visual design was cohesive and consistent, with a clear brand identity and a visually appealing aesthetic.

To ensure that the app met the needs of users, I conducted several rounds of usability testing with real users. I gathered feedback from users and used this information to iterate on the design and improve the app.

Some of the improvements we made as a result of user feedback included:

• Adding more detailed instructions for using the journaling and mood tracking features.
• Streamlining the process for connecting with other users and offering support.
• Improving the AI-powered mood prediction feature to provide more accurate and relevant insights.

Overall, the app was well-received by users and met the needs I identified through my research. Users reported that they found the journaling and mood tracking features helpful in tracking and improving their mood, and they appreciated being able to connect with and support others who were struggling with similar issues. The AI-powered mood prediction feature was also a hit, with users finding it helpful in understanding their mood patterns and identifying potential triggers.
