Track every step of your health & fitness journey
Performing every day requires an understanding of the relationship between your physical exertion, mental load, and your body’s ability to bounce back. From sleep to stress, and steps to recovery, WHOFIT captures everything to coach you towards your best performance.

Sleep is more than time in bed
Improve recovery, boost your immune system, and make performance gains with better quality sleep. WHOFIT measures all four types of sleep with lab-level accuracy, and will suggest optimal bedtimes based on what your body needs to recover.

Sleep quality quantified

01 Track your sleep stages
WHOFIT tracks all four stages of sleep — slow wave sleep (SWS), REM, light, and awake — with near-perfect accuracy. Each stage serves a different purpose in your recovery.
02 Understand your sleep need
WHOFIT calculates how much sleep you really need based on recent sleep patterns, the strain from the day, sleep debt you’ve accrued, and any recent naps you’ve taken.
03 Optimize your sleep performance
Quality of sleep is just as important as quantity. WHOFIT monitors your wake events, efficiency, and respiratory rate to deliver daily recommendations on how to get your best sleep every night.
04 Build your optimal sleep schedule
WHOFIT helps you schedule your bed and wake times based on how strenuous your day was, when you need to wake up, and how you’re looking to perform the next day. You can also set custom haptic alarms that will wake you when you’re fully rested, or at a specific time.
05 View your sleep trends
See your sleep performance over the week, month, or year to identify patterns and build a better bedtime routine.


Strain
Understand the impact of everything you do
Whether you’re out for a run, delivering a work presentation, or doing yard work, WHOFIT measures all of the physical and mental demands put on your body. The result is a Strain Score that represents your body’s total daily exertion.

Recovery
Be ready to perform your best
The WHOFIT Recovery Score measures how your body is adapting to the stresses of training, lack of sleep, illness, or your menstrual cycle. The more recovered you are, the more your body is signaling it’s ready to take on more. The less recovered you are, the more your body is telling you it’s best to take it easy.
66% of members with a goal to improve their recovery saw higher average recovery scores
