BMI and Calorie Tracking Should Live Together
BMI is the simplest body-mass-status indicator. Calorie tracking is the daily intake side. Apps that show them on separate screens force users to manually correlate; apps that overlay weight on calorie trends close the loop automatically.
How We Evaluated
- BMI calculation free
