Research
Why do people give up on wellness tracking?
Competitor analysis
I reviewed Bearable and Daylio. Both needed several steps to log even simple information, which adds friction to a task people repeat every day.
Design
Six wireframes mapped the four core areas before any code: overview, editor, calendar and diary.
Build
A working Android prototype, built to compare design choices.
Two ways to navigate, two colour modes
I built the diary, wellness logging and navigation flows in Android Studio. Each flow worked with buttons or gestures, in light or dark mode, so the study could compare them head to head.
The recording walks through the finished prototype: checking in, logging a diary entry, and signing in.
Testing
Does navigation style or colour mode change how well people log their day?
Study design
8 participants completed both tasks under all four conditions: gesture or button navigation, in light or dark mode. Each round used different content, shown in the table.
Tasks
Step 1: Write a diary entry
From home, open the diary, write the given message, set today’s date, save and return.
Step 2: Log a wellness check
From home, open the calendar, pick today, enter the given wellness details, save and return.
Results
Buttons for precision, gestures for expression, light mode for reading.
A hybrid design
Buttons worked best for structured input. Gestures felt natural for journaling and sliders. Light mode won on readability.
The final app uses buttons for accuracy and gestures for expressive actions.
It felt as if I was flipping a page.
P6, on diary gestures
It was smoother than the other gestures. Maybe because it’s a diary, but it felt more natural.
P1, on diary gestures
Even my health app on my phone is on light mode. It’s kind of motivating when it’s brighter.
P4, on colour mode
Learning outcomes
Test the interaction, not just the screens
Comparing gestures with buttons showed each one suits a different kind of task. A single design would have hidden that.
Preference can outweigh efficiency
Dark mode saved battery, but people chose light mode because it was easier to read. I designed for what they actually preferred.
Building it sharpened the design
Developing the prototype in Android Studio made me define every state and transition, not just how each screen looks.
