Developed by sleep scientist Professor Leon Lack, use one of THIM’s many novel features: β€’ IMPROVE SLEEP – THIM offers a unique sleep-conditioning program designed to help you fall asleep sooner and reduce wakefulness across the night. β€’ TRACK SLEEP QUALITY - Use your phone to track your sleep quality throughout the night including stages of sleep and periods of wakefulness. β€’ POWER NAP – THIM determines when you fall asleep to the nearest minute. No other device can deliver this accuracy.

Use this feature to ensure you wake from a light stage of sleep so you bounce out of bed in the morning and enjoy a great start to the day. β€’ MONITOR SLEEP EFFICIENCY – THIM provides a unique sleep efficiency score for each night of sleep. This algorithm is used by sleep clinics to score sleep studies. β€’ JOIN OUR COMMUNITY – Join thousands of people whom have traded in their non-assistive sleep tracker for a product, which contains novel, evidenced-based programs to improve and optimize your sleep.
