What You'll Learn
Understanding the app's sleep tracking features
Sleep apps can monitor your sleep using biometrics like heart rate, blood oxygen saturation, and respiratory rate. They can also use sound recordings or movement sensors to track how often you are restless throughout the night. This data is then used to compile an easy-to-read analysis of how well you slept and the different sleep stages.
Some sleep apps track the duration and quality of sleep and can provide valuable data. They can also offer soothing sounds or strategies to help you relax and fall asleep. Sleep Cycle, for example, uses sound analysis to track and improve sleep for millions worldwide. It measures duration, sleep stages, and interruptions throughout the night with unparalleled accuracy. It also allows you to wake up during your lightest sleep phase to start your day smoothly, with a selection of pleasant alarm sounds.
The SleepWatch app uses information including sound, the time you go to bed, and data from the Apple Watch, like heart rate and movement, to track your sleep cycles. Pillow is another app that offers a free option and provides audio recordings, sleep trends, heart rate and oxygen saturation tracking, sleep sounds, a nap mode, bedtime reminders, and personalized insights and tips to improve your sleep.
While sleep apps can be incredibly useful for people who want to know how many times they wake up during the night and why, it's important to remember that they should not be used as a replacement for medical advice or a clinical sleep study. They can, however, be used to gather additional information and help develop healthier sleep hygiene habits.

Using the alarm clock function
Sleep Time is a comprehensive sleep analysis app and alarm clock. It has over 35 million users and is the first sleep app with iOS 8 support and Apple Health integration.
To use the alarm clock function, you can set the alarm clock with a single gesture. You can choose to fall asleep to soundscapes or white noise, and the alarm will even ring if your phone is on silent mode. You can choose from 20 built-in alarms or wake up to your favourite song from iTunes. The alarm volume is adjustable.
The app also has a sleep timer for cutting off music when you start to snooze, a shake-to-turn-on-flashlight option, and snooze options. Unlike some other alarm clock apps, Sleep Time supports background alerts, so you'll receive an alarm even if the app isn't running all night.
Sleep Time also offers a premium version with unlimited access to premium programs and workouts, HD videos, dynamic and motivational audio, workout summaries, and more.

Interpreting sleep data and analysis
Sleep apps can monitor your sleep using biometrics like heart rate, blood oxygen saturation, and respiratory rate. They can also use sound recordings or movement sensors to track how often you are restless throughout the night. This data is then used to compile an analysis of how well you slept and the different sleep stages. While no app offers objectively accurate sleep analysis, they can help you glean trends and patterns, which may help you improve your sleep over time.
Sleep apps often present data in the form of graphs and charts. While these can be impressive, they are useless if they are not easy to interpret. Clearly labelled axes and reports in everyday English can help make the data more accessible. Some apps also provide a sleep score, which measures how well you slept and provides an in-depth analysis based on the length of sleep, whether you were in light, deep, or disrupted sleep, and variations in heart rate.
Sleep apps can also provide actionable advice based on your sleep data. For example, reminding you to get to bed more consistently or letting you know when you may be sleep-deprived. This awareness can help you develop healthier sleep hygiene habits. Additionally, some apps offer soothing sounds or strategies to help you relax and fall asleep faster.
It's important to note that sleep apps should be used to gather additional information and not as a replacement for medical advice or a clinical sleep study. If you have concerns about your sleep, it's always best to consult a healthcare professional.

- Audio recordings
- Heart rate and oxygen saturation tracking

Comparing Sleep Time with other sleep tracking apps
Sleep Time (or Sleep Cycle) is a sleep tracking app that uses sound analysis to track and improve sleep. It measures duration, sleep stages, and interruptions throughout the night. The app also provides pleasant alarm sounds to wake you up during your lightest sleep phase. It also allows you to replay nighttime sounds and provides a guided journey into restful sleep. The free version of the app provides four alarm sounds and will track your sleep indefinitely. The premium version costs $30 per year and provides 17 additional alarm sounds and new Sleep Aid content.
Sleep Cycle is similar to other sleep tracking apps such as SleepScore, Pillow, and SleepWatch. SleepScore provides a detailed analysis of sleep duration, the amount of time it took to fall asleep, light sleep, deep sleep, REM sleep, and wake time. The premium version of SleepScore, priced at $6 per month or $50 per year, allows users to set goals and provides advice on how to achieve them. Pillow is another sleep tracking app that offers audio recordings, sleep trends, heart rate and oxygen saturation tracking, sleep sounds, a nap mode, bedtime reminders, and personalized insights and tips to improve sleep. The Pillow app is available for a monthly fee of $9.99, $59.99 quarterly, or $39.99 annually. SleepWatch is an app that integrates with the Apple Watch to track sleep cycles using sound, bedtime, heart rate, and movement data.
While Sleep Cycle and other sleep tracking apps can provide valuable insights into sleep patterns and quality, it is important to note that they may not offer completely accurate sleep analysis. A study found that the Fitbit Charge 2 detected sleep onset with 96% accuracy but overestimated time spent asleep by nine minutes on average. Another study found that the Whoop sleep tracker was 99.7% accurate in measuring heart rate and 99% accurate in measuring heart rate variability during sleep. The Oura Ring, which works with the Oura app, was found to be 96% accurate when all data points were recorded and used in combination with its sleep-tracking algorithm.
Overall, Sleep Cycle and other sleep tracking apps can be useful tools for monitoring sleep patterns and improving sleep hygiene. While no app can provide perfectly accurate sleep analysis, they can help users identify trends and patterns to improve their sleep over time.
