REM Sleep Calculator & Sounds app for iPhone and iPad

Waking up at the right time feels like waking up naturally without an alarm.

With REM, wake up feeling refreshed and fall asleep listening to soothing sounds such as Light Rain, Thunderstorm, Summer Night, Meditate, White Noise, and much more.

REM Sleep Calculator uses the average sleep cycle of 90 minutes along with the length of time it takes for you to fall asleep to calculate the moments of time you will be in your lightest sleep.

Disclaimer: REM Sleep Calculator may not work for you under the influence of alcohol or other drugs due to the disruption of sleep cycles.
