About
Hey Product Hunt! š I'm Muzammal, and I built SmartSleepCalc because most "sleep calculators" online are just basic bedtime timers. SmartSleepCalc is different ā it's 7 clinically-referenced tools in one: ā° Sleep Cycle Calculator (wake at the right moment) šµ Deep Sleep Calculator (how much SWS do you need?) š REM Sleep Calculator (by age) š Sleep Efficiency Calculator š“ Epworth Sleepiness Scale (clinical fatigue score) š STOP-BANG (sleep apnea risk assessment) ā” Sleep Debt Calculator 100% free. No signup. No app. Works on any device. I'd love your feedback ā especially: which calculator did you find most useful? And what would you add? ā https://www.smartsleepcalc.com
