About Health Score: Diet & Macros
Health Score turns your body measurements into one clear number and an actionable plan. Enter your height, weight, activity level and goal, and the app calculates your Health Score out of 100 alongside your BMI, BMR, ideal weight range and daily calorie needs.
With more than 100,000 downloads, this is the most widely used app in the AppColors portfolio and the flagship example of the health-and-fitness work I build in Flutter.

Frequently asked questions
How is the Health Score calculated?
It combines your BMI, your stated activity level and your goal into a single score out of 100, so you can see at a glance whether your current numbers line up with what you are trying to achieve.
Is the diet plan personalised?
Yes. Your calorie target and protein, carb and fat macros are calculated from your own measurements, activity level and goal rather than a fixed template.
Do I need an internet connection?
Core calculators and tracking work without a connection. Some recipe and sync features benefit from being online.
Is the app free?
Yes, the app is free to download on Google Play.
