sleep - 2 - Peak Reaction Time

Sleep-2-Peak is perhaps the most sensitive non-invasive scientific tool for measuring your fatigue and alertness.  You can figure out your unique circadian rhythm with this app.

This is a validated task:

Brunet, J. F., Dagenais, D., Therrien, M., Gartenberg, D., & Forest, G. (accepted). Validation of sleep-2-Peak: A smartphone application that can detect fatigue-related changes in reaction times during sleep deprivation. Behavior Research Methods, DOI: 10.3758/s13428-016-0802-5

>10 poster publications that validate the use of the app for measuring physical and cognitive states.

The app was developed by a neurologist and cognitive psychologist with expertise in sleep and alertness.  After years of personally testing the app and submitting the findings to various sleep conferences, the app was recently tested in a University research setting in a group of individuals and preliminary data suggest it to be equivalent to the gold standard alertness tasks in the scientific community. (Validation article pending)

Save and export the data for yourself or contribute to our reaction time database. We believe that this data is yours and you get access to all the fine grained aspects of the data!

The application was developed to be sensitive to detecting:
- Sleep need
- The circadian rhythm (alertness variation with time of day and body rhythms)
- Mental and physical capacity (results shown to correlate with mental and physical performance)
- Influence of substances

By using sleep-2-Peak, you will become aware of alertness variations beyond what you can feel and you will discover how powerful your schedule choices can be to boost your performances naturally.
