Sleep Tight

Sleep tight works out the best time for you to sleep for based on 90 min sleep cycle then sets an alarm for that letting you wake up with much more ease, this also takes
into account the time it would take you to get to sleep, the average for most people is 14 min but this can be changed in the settings.

we would recommend you try to get 7 and a half -9 hours of sleep every night but we also have alarms from just 90 min to 13 hours.
