Although most users praised the Focus Keeper’s simplicity, many of our users had been expressing their challenges regarding certain UX pain points and their desire for task-tracking features. To gain further insight, I delved into the reviews from the App Store, YouTube, and VoC channels and researched competitors’ UX solutions for task and habit management.

Our first initiative was adding the task management feature. Although well-established task management and habit tracker apps follow some common UX patterns, we had to create a unique solution by combining the task management feature with the Pomodoro timer.
After conducting internal testing for various designs, I finalized the card design that simultaneously displays task status and timer information.

Focus Keeper features a distinctive user interface characterized by its simple design and iconic red color. This factor, which contributed to the app's viral success and easy recognition, was crucial for us to consider during the design process.
Below, I highlighted some of the major pain points identified in the previous timer screen. I developed an intuitive method to navigate between task and chart screens, preserving the iconic appearance while tackling usability issues.

Before making the update available to the public, we decided to validate our solutions and identify any significant issues that could emerge with the new user experience. I led these moderated and unmoderated user tests and observations. We identified two major pain points that could be addressed within the time and resource constraints before launching to the public.

Due to time and development constraints, we launched the new chart screen a few months after the renewal.
Previously, the task analysis only displayed the duration of focus sessions for the past 30 days. Users needed to interact with specific data points on the graph to see the total session counts for a particular day.
The new chart update aimed to provide a better user experience for analyzing timer and task features. The new subscription-based membership system made it mandatory to consider which features should be free or pro during the design process. The overview section was designed to be available for all users, while task-specific data was designated for pro users only.

As the App Store was saturated with similar Pomodoro timers and task management tools, crafting outstanding user experiences was key. Our strategy focused on developing a Minimum Lovable Product (MLP) that surpasses the Minimum Viable Product (MVP) by providing delightful user experiences.
However, creating a delightful experience requires design and development resources, so it was necessary to focus on the most effective experience that would delight all users. Focusing on the custom floating tab bar and task interaction emerged as prime candidates, considering they would be used by all our users and their significant contribution to the simplicity and iconic look of the timer.

Due to the constraints of legacy code, much of Focus Keeper had to be developed from scratch. I collaborated with developers to create a design system to lower design and development costs and ensure a consistent visual identity. The design system adopted the atomic design methodology, organizing Colors, Fonts, Elements (atoms), and Components (molecules and organisms).
Given our users' strong interest for the iPad version and landscape mode, ensuring a consistent user experience across different devices and orientations became a key priority. Therefore I created a responsive layout guide that would support all iOS and iPad OS devices including portrait, landscape and split view modes.

Due to time and development constraints, we released the redesigned chart screen four months after the initial release.
Upon introducing the new chart screen and highlighting its value during the onboarding process, we observed an increase in the new user subscription rate by 58.7% and task creation rate by 19.1%. Indicating that users who can analyze their task data are more willing to subscribe. Additionally, we achieved our goal of increasing the average chart view count per day by 17.1 percent, showcasing that the page became more useful.
