How to set a bedtime

The first time you set a bedtime, the Clock app asks you a few questions:

Download SmartSleep 3.22 for Mac from our software library for free. The application is included in System Tools. The current installation package available for download requires 3.1 MB of hard disk space.
‎Sleepez is a smart sleep tracker that analyses your sleep cycles to help you learn more about your sleep and teach you how to get a healthier sleep. Sleepez can also be used as a smart alarm clock to wake you up at the lightest moment of daily sleep cycles. With soothing alarm melody, every day is.

My low rating is for the new app version of SmartSleep. I bought the app and used it for a couple of weeks, but recently uninstalled it and switched back to the free prefpane version. I really liked the new menubar item, but the actual 'smart' sleep feature only works if the app is running all the time, which is an annoyance.

Open the Clock app and tap the Bedtime tab.
Tap Get Started and choose your settings.
Tap Done.

After you set a bedtime, your iPhone reminds you when it's time to go to bed, and an alarm sounds when it's time to wake up.

Turn Bedtime on or off

Open the Clock app and tap the Bedtime tab.
Under Schedule, tap Bedtime or Wake Up.
In the top-right corner, turn Bedtime Schedule on or off.

This turns off both the bedtime reminder and the wake up alarm.

Change the time and which days you get a reminder or alarm

Open the Clock app and tap the Bedtime tab.
Under Schedule, tap Bedtime or Wake up.
Drag the Bedtime button or the Alarm button . As you drag, your Bedtime reminder and Wake Up alarm automatically update.
Under Days Of Week Active, tap the days that you want to get reminders or alarms. Days that are orange are active.

Track your sleep history

Open the Clock app and tap the Bedtime tab.
Scroll down to your Analysis, which shows your recent history.

If you use your iPhone when you're supposed to be in bed, you won't get credit for that time. Or, if you snooze the Wake alarm, the time that you stay in bed updates to match.

Data from Bedtime also automatically appears in the Health app.

How to change the settings

Open the Clock app and tap the Bedtime tab.
In the top-left corner, tap Options.
Here's what you can change:
- Set when you're reminded to go to bed.
- Turn Track Time in Bed on or off. This gives you a better understanding of your sleep patterns by tracking when you use your iPhone during the night.
- Turn Do Not Disturb During Bedtime on or off. During bedtime, the Lock screen dims, calls and alerts that arrive when your device is locked are silent, and notifications go to your history.
- Choose a Wake Up Sound for your alarm.
- Change how loud the alarm is.
Tap Done.

How to view your history in the Health app

To track your sleep analysis in iOS 13, open the Clock app, tap the Bedtime tab, then tap 'Show more in Health.' Your Sleep Analysis shows the amount of time that you spend in bed or asleep.

Bedtime in the Clock app tracks time that you spend in bed, but not how much you sleep or move. Your Apple Watch also doesn't track sleep or time in bed.

To track how much time you sleep, try using a sleep tracker with the Health app. You can also manually enter how much time you sleep: Open the Clock app, tap the Bedtime tab, then tap 'Show more in Health.' In the upper-right corner, tap Add Data. Learn more about the Health app.

In this review, we are going to look at the innovative Sleep Cycle App, which is designed to improve your sleep.

Although health experts emphasize time and again that we need to sleep well and enough for an array of benefits, including stress relief and better mood, 10 to 15% of the total world population experience habitual sleeplessness. This review analyses the effectiveness of the app in improving your sleep pattern.

So, What is the Sleep Cycle App?

Sleep Cycle App is a leep tracker with a smart alarm feature. It is designed to keep track of your sleep patterns and achieve the best rest from your sleep. According to its developers, you can use the app to find your ideal sleep and wake up time.

Besides, the app doubles up as an alarm that wakes you up in light sleep during your selected and appropriate wake-up alarm time. As a result, it makes you wake up feeling as easy and relaxed as you would without using an alarm.

How the App Works

Sleep Cycle App uses an inbuilt microphone or accelerometer for sound and motion detection/analysis, respectively, to keep track of your movements while asleep. The app finds your different sleep phases by detecting specific body movements using sound and accelerometer.

If you want to learn more about how sleep tracking apps and sleep tracker devices work, this article can help you to understand the basics.

What You Need to Know About Sleep Cycle

In case you didn't know, you normally undergo aseries of sleep cycles while asleep. The duration of a full sleep cycle is approximately 90 minutes, during which you go through five stages of sleep.

The initial phase is typically characterized by light sleep.
The second one prepares you for deep sleep.
You fall in a deep sleep in the third phase
The fourth one is when you maintain a deep sleep.
The fifth is called rapid eye memory (REM) sleep.

In a normal situation, the cycle repeats numerous times a night.

What the App Does

So, what this sleep analysis app does is to track your lightest sleep phase in a sleep cycle using either of its detection modes. Then, it uses the 30-minute alarm window you've set to wake you up gently during the light sleep phase.

If you'd like to snooze, the app has the corresponding functionality too. Better still, it gives you an option to use the intelligent or the regular snooze by just a tap on your phone or picking up the phone.

In case you want to snooze through your ideal wake up phase, the intelligent snooze mode will be the better choice. While in the mode, the sleep stage alarm clock snoozes regularly but with gradually reducing snooze durations. The snoozing wakes you up completely but gently from sleep.

On the other hand, in regular snooze mode, the app allows you to select a definite snooze time. However, the snooze period has to be within one to twenty minutes. While in this mode, you can snooze as many times as possible.

Generally, the app is designed to show and improve your sleep quality.

How Does the App Measure Your Sleep Quality?

There are four parameters that the app uses to measure the quality of your sleep (sleep quality score). They include:

The number of hours you spend in bed per day
The number of hours you spend in deep sleep per day
The consistency of your sleep pattern
The number of times the Sleep Cycle App shows that you are entirely awake.

The app will start by showing your sleep quality score right from the very first night. However, the readings for the first few nights might not be precise, but with time, the sleep data becomes more meaningful and provides more accurate statistics of your sleep patterns.
