Sleep Cycle: Sleep Tracker

Track how you sleep

Sleep Cycle: Sleep Tracker is a sleep-monitoring and smart-alarm app for people who want a clearer picture of their nights without wearing a dedicated device. It uses sound and movement picked up by your phone to follow sleep patterns, then presents the results as easy-to-read sleep records and trends.

A gentler way to wake up

Set a wake-up window and Sleep Cycle aims to rouse you during a lighter stage of sleep rather than at one exact point. That makes it a useful fit for anyone who often wakes feeling groggy or wants more flexibility than a standard alarm provides. The app also records sounds such as snoring, coughing, or talking, which can help reveal interruptions you may not notice yourself.

Turn nightly data into useful context

Sleep Cycle gives each night a sleep-quality view based on factors such as duration and movement. Over time, these records can help you spot patterns rather than judging one poor night in isolation. Sleep notes let you mark habits and conditions including caffeine, exercise, or stress, making it easier to compare daytime choices with how you slept.
