Sleep Boost APK

Adds absolute motion tracking to log file for us in experiments

Sleep Boost is an app designed to enhance the benefits of sleep on memory and other cognitive abilities. It uses motion sensors in your phone to detect when you enter deep sleep, and delivers auditory stimuli (white noise) timed to encourage your brain to produce slow oscillations which improve memory (http://www.ncbi.nlm.nih.gov/pubmed/25389394)

Sleep Boost can also log data on your sleep depth and supports double-blind controls so you can run your own experiments!
