Case Study - Weight Tracker Mobile App

Overview

Weight Tracker makes it simple to log your weight, monitor your BMI, and stay on top of your nutrition — all in one beautifully designed app.

Users can log daily weigh-ins with optional notes and watch their progress unfold on an interactive chart. The app supports viewing data across different time ranges — one week, one month, three months, or all time — and switching between weight and rate-of-change views to understand trends.

A built-in goal suggestion tool calculates a healthy target weight based on established medical formulas (Hamwi, Devine, Robinson, Miller), while a visual progress ring and smart prediction estimates when the goal will be reached based on current pace.

The dashboard shows BMI with a color-coded scale, tracks lean body mass and body fat percentage, and provides personalized daily calorie and macronutrient targets with five preset options — Balanced, Low Fat, High Protein, High Carb, and Ketogenic.

Users can also track medication doses alongside their weight journey, recording the dose, date, body location, and notes for each entry. All data stays on the device with no accounts, cloud sync, or tracking required.
