DNA-powered personalized fitness, nutrition and recovery
A saliva DNA test maps genetics related to fitness response, nutrition and recovery, producing an actionable blueprint rather than a raw report.
Connects wearable sensor data to track activity, sleep and daily readiness, feeding those signals back into your weekly plan.
Your exercise, nutrition and recovery plan is rebuilt each week from your goals and latest biometric data so it never goes stale.
Choose a focus such as losing weight, building strength, increasing longevity or supporting GLP-1 treatment, and the plan adjusts accordingly.

Find a realistic bedtime or wake-up time around 90-minute sleep cycles
Enter the time you must wake up to get bedtimes, or choose the 'going to sleep now' option to get suggested wake-up times from your device's current clock.
Instead of one answer, the tool returns six candidates so you can pick what fits your evening rather than being forced into a single rigid bedtime.
The plan automatically allows about 15 minutes before the first cycle starts, so suggestions reflect real bedtime behaviour.
Times are spaced in 90-minute intervals and labelled by cycle count, which makes five- versus six-cycle trade-offs easy to compare.
