Renight
Make every minute of your sleep count with Monaural Beats.

Renight is a sleep optimization app that plays Monaural Beats — scientifically backed sound waves — to improve sleep quality through brainwave entrainment. It targets people who are sleep-deprived or time-constrained, helping them fall asleep faster and achieve deeper sleep. The app claims to boost deep sleep brainwaves by 18% and increase deep sleep by 56%, based on external research studies.
The app plays sleep-inducing Monaural Beat sound waves that entrain the brain into deeper sleep (delta wave) states through auditory stimulation.
