How we sleep?
Sleep is a naturally recurring state of mind and body characterized by altered consciousness, relatively inhibited sensory activity, inhibition of nearly all voluntary muscles, and reduced interactions with surroundings. Sleep occurs in repeating periods, in which the body alternates between two highly distinct modes known as non-REM (non-rapid eye movement) and REM (rapid eye movement) sleep.

Sleep occurs in cycles of approximately 90 minutes. This rhythm is called the ultradian sleep cycle. Sleep proceeds in cycles of NREM and REM, normally in that order and usually four or five such cycles per night. The American Academy of Sleep Medicine (AASM) divides NREM into three stages: N1, N2, and N3, the last of which is also called delta sleep or slow-wave sleep. The whole period normally proceeds in the order: N1 → N2 → N3 → N2 → REM. REM sleep occurs as a person returns to stage 2 or 1 from a deep sleep. An adult reaches REM approximately every 90 minutes; REM sleep usually lasts for longer during latter half of sleep than in the early part of the sleep episode. There is a greater amount of deep sleep (stage N3) earlier in the night, while the proportion of REM sleep increases in the two cycles just before natural awakening.

Awakening can mean the end of sleep, or simply a moment to survey the environment and readjust body position before falling back asleep. Sleepers typically awaken from slow-wave sleep, soon after the end of a REM phase or sometimes in the middle of REM. Internal circadian indicators, along with successful reduction of homeostatic sleep need, typically bring about awakening and the end of the sleep episode.
How sleep tracker and alarm work together?
The application uses sleep tracker. It receives data from motion sensor and it tracks your sleep patterns (your movements vary with each sleep phase). It creates night chart with your sleep cycles.


Alarm can have wake up phase, which is time interval (default 30 min.) during the application wake you up in your lightest sleep phase.
How snooze works?
The application has two snooze modes:
1. Automatic snooze lets you snooze through your wake up phase. Each snooze duration becomes shorter, gently bringing you from asleep to completely awake at your desired alarm time.
2. Manual snooze lets you choose a specific snooze time between 1-20 minutes. You can snooze an unlimited number of times.

Snooze can be activated of shaking device or tapping button “Snooze” on the main screen.
How is sleep quality calculated?
Sleep quality is calculated from frequency of your movement, time in bed and wake up mood (if enabled). Higher sleep quality is better. The average sleep quality is 60-75% (our testing).
What is correct device placement?
Variant A: Place your device on the mattress (top corner) out of the way of the pillow to work smart alarms and to calculate sleep quality correctly. If the battery is not fully charged, it’s recommended to connect your device to a charger.

Variant B: Stop snoring using just vibration: Bandage up the iPhone to your arm. Remember to place the iPhone upside down with the microphone facing up. The iPhone battery should be fully charged.
Does application work:
• in background mode,
• with the screen locked,
• with Do Not Disturb,
• with Airplane Mode and
• with Silent Mode?
Yes, it does.
How does sleep recorder work?
The application records your talk or snoring while you are asleep and it has 2 modes:
A: Records all noises above custom sensitivity level.
B: Records only snoring using smart snoring detection.
It also creates the graph of noise in room during the night and takes the total time of snoring down.


If you want to play your recordings, go into “History” section using side menu (button with 3 lines at upper-left of the screen). Select first report (it’s your last night). Tap segment button “Recordings”. There you can find all your recordings from selected night.

Recordings use one of the best compression AAC (Advanced Audio Coding). AAC generally achieves better sound quality than MP3 at similar bit rates.
When sleepy sounds stop playing?
Sleepy sounds have 2 modes of stop playing:
Automatic - it uses sleep tracker functionality for detection when you fall asleep. After that the application stops playing of sleepy sounds.
Manual - you can manually set playing duration.
How does snore detection work?
It’s here! Mature and smart snoring detection.

Have a perfect overview of snoring during your sleep. The latest application update (Prime Sleep Recorder, Snore Control, Sleep Recorder Plus, Sleep Center, Snore Stopper) brings the most advanced technologies of sound processing.
By using artificial intelligence (A.I.), new Apple machine learning technology and a large number of snoring samples, our application is able to achieve the high accuracy in snoring detection and in statistics of night reports.
And that’s not all. By continuous expansion of the sounds database, our application will be smarter and more accurate in all its functions.
What is stop snoring function?
It tries to stop your snoring by playing chosen sound or using iPhone vibration when the snoring is detected.
Does application support Apple Health?
Yes, the application fully supports Apple Health App. You can activate or deactivate this under Settings → Apple Health. It writes the sleep analysis data to Apple Health.
Does application support Apple Watch?
Yes, it does.
