Frequently Asked Questions
Can I use the Fitness & Health for medical diagnosis?
No, the Fitness & Health is strictly for educational and screening purposes. Always consult a healthcare professional or doctor for medical advice and diagnosis.
How often should I use the Fitness & Health to track progress?
For most health metrics, checking weekly or bi-weekly provides a much more accurate trend line than daily checking, which can fluctuate due to hydration and sleep.
Does the Fitness & Health account for body composition?
Standard formulas rely on baseline metrics. If you are a highly trained athlete or have atypical body composition, you should rely on clinical measurements rather than standard calculator outputs.
