Frequently asked questions
Q. Which BMI standard is used?
WHO Asia-Pacific thresholds: underweight < 18.5, normal 18.5–22.9, overweight 23–24.9, obese 25+.
Q. How does the sleep calculator work?
It uses 90-minute sleep cycles to back-calculate ideal bedtimes or wake times so you end a cycle naturally.
Q. How are BMR and the calorie calculator different?
BMR is your basal metabolic rate (calories burned at rest). The calorie calculator multiplies BMR by activity level to estimate daily needs.
Q. Can I sync records across devices?
Not at this time — data stays on the device you used to enter it.
