Daily Health Tracker

Personal Wellness Mobile App

01 — Problem

The Challenge

People managing chronic conditions like diabetes needed a tracking app that felt approachable rather than clinical — one that made daily data entry feel like a habit, not a chore.

02 — Process

My Approach

Designed a color-coded tile system that mapped meal timing, blood glucose, and activity to a calendar grid — giving users an at-a-glance view of their day without cognitive overload. Used warm, calming visuals to reduce anxiety around health data.
