Is Nightly safe?
When creating Nightly, we first and foremost focused on your safety. That’s why we chose to use the already existing tested technology in your smartphone to deliver our solution. We also made sure that Nightly works in Airplane Mode with all the networks turned off. Until our global launch in Jan 2018, Nightly was used during over 17,000 nights with no issues reported.
Who created Nightly?
Nightly was created and is continuously developed by a team of neuropsychologists, engineers, audiovisual experts and entrepreneurs working closely, using methodology and technology based on existing knowledge and studies, with a mission to help people sleep better.
How long does it take to start seeing the results of using Nightly?
This can vary slightly depending on the problems you’re experiencing, your mental and physical condition, and motivation. During our tests, we observed first noticeable results after seven days. However, in various circumstances and environments, it may take anywhere from one night to two weeks before you get visible effects.
Should Nightly be used only for nighttime rest or can I use it for a nap?
You can also use it for a nap.
What is the Sleep Stimulation technology?
Sleep Stimulation technology is a combination of proven science and available technology to have an active impact on the quality of sleep. It involves AI-based algorithms that use specially designed videos and sounds to first, help the user unwind and easily fall asleep, and then, monitor sleep, detect moments of vulnerability and respond with soothing sounds to help maintain uninterrupted, healthy sleep.
Does the app play the music all night?
No. Nightly activates itself only when it detects a possibility of a sleep disturbance. When it does, it plays short sounds that help you relax and maintain uninterrupted sleep without bad dreams.
Can I set the smartphone on the nightstand?
No. Nightly needs to measure your movement during the night in order to work correctly. It is done using the accelerometer inside your smartphone. Therefore, the smartphone needs to be on your bed to accurately detect movement. Otherwise, the sleep tracking and stimulation will not work properly.
Should the app be turned on the entire night?
Yes, because our Sleep Stimulation technology starts with helping you fall asleep and continues throughout the night. Without it, the Nightly app will not be able to measure and influence your sleep performance.
What are the available language versions?
Nightly is available only in English.
Is Nightly appropriate for kids?
Nightly was not tested on kids.
What if I use the Nightly app and still have problems with sleeping?
In such case, we recommend contacting your GP.
Technology & performance
What’s the evidence that Nightly works?
Our Sleep Stimulation technology is based on over 25 years of research on sleep. It is proven that the right sounds played at particular moments can facilitate falling asleep, help sleep through the night and limit bad dreams. Nightly’s team conducted a sleep lab study at the Institute of Psychiatry and Neurology to check the accuracy of Nightly’s technology. It has proven that our method not only does not disturb but actually adapts to your sleep architecture, improves sleep efficiency and decreases the number of wakeups during the night and appearance of bad dreams.
How is sleep efficiency calculated?
To calculate your sleep efficiency, Nightly monitors and evaluates your sleep in four main areas: sleep length, regularity of sleep time, falling asleep duration and waking up duration.
How does Nightly recognize sleep stages?
The app uses your phone’s built-in accelerometer to sense the patterns of your body movements, and based on that, with the help from AI-based algorithms, it can assess your sleep stages and adapt to them.
Are there any side effects of using Nightly?
There were no negative side effects reported by Nightly users or by the Institute of Psychiatry and Neurology in Poland where the app was tested. However, if you observe any discomfort when using the Nightly app, we recommend to immediately stop using it and contact us: firstname.lastname@example.org
Are there any adverse reactions to using the Nightly app?
Nightly is not a medicine or a medical product. There have been no reports of any adverse reactions by Nightly users who have slept over 17,000 nights with it (until Jan 2018) or by the Institute of Psychiatry and Neurology in Poland where the app was tested. However, if you notice any discomfort or side effects of using Nightly, we recommend to immediately stop using the app and contact us: email@example.com
On what devices can I use Nightly?
All devices with iOS 10 and higher or Android 6.0 and higher.
How much battery does Nightly need?
Nightly may use up to 30% of your battery over the whole night, so either make sure you have enough battery life before going to sleep or plug your phone in. Remember, however, to put the phone next to you on the mattress.
Will the app still work if the screen is locked?
Yes. As a matter of fact, we recommend to lock it.

Sleep Stimulation Technology
Which Relaxing Theme should I use?
All the audio-visual themes are scientifically designed and tested to help you feel relaxed. However, everyone is a bit different – you can pick the one that suits you most.
Is there a need to change the Theme over time?
Due to the habituation process (adjustment to stimulus), we recommend changing the Theme monthly.
How can I turn off Sleep Stimulation?
After watching a relaxing video, you enter Sleep Mode. The ‘Sleep Stimulation’ option is located at the bottom of the sleep mode screen. You can turn it off by simply swiping it.
What happens when I turn Sleep Stimulation off?
If you turn Sleep Stimulation off, no calming sound patterns will be played during the night. These sounds are a key element of Nightly’s unique technology designed to improve the quality of your sleep. If you turn them off, the app won’t be able to decrease the number of unwanted wakeups and help reduce the occurrence of bad dreams. That’s why we recommend leaving Sleep Stimulation on.
How many times a night does Nightly audio-stimulate our sleep?
The number of stimulations may vary each night. Usually, it turns on several times.
How does the app know that I fell asleep?
Nightly monitors sleep phases on the basis of the data provided by the accelerometer (body movement detector) in your phone and an AI-based algorithm.
What if my phone falls off my bed during the night?
If it happens, make sure to place it more securely next time. When the phone is off the bed, the app is not able to track your movement and determine your sleep stages. As a result, Sleep Stimulation and the Intelligent Alarm will not work.
What if I share the bed with another person?
Nothing to worry about! Nightly also works great when there are two people in bed. Just be sure to place the phone on your side.
What’s the optimal volume of the sounds played during the night?
We indicate the recommended volume level in the app. However, feel free to adjust it according to your needs, since people’s hearing and preferences vary quite a bit.
Nightly & Sleeping Patterns
Isn’t the app somehow interfering with my normal sleeping patterns?
No. Actually, it adapts to your natural sleep stages to do its job. Nightly uses your phone’s built-in accelerometer to sense your movement patterns at night. This data is then used to estimate the sleep stages and adapt the app’s activity to your needs.
What should I do if the sounds wake me up at night?
It should not happen. If that’s the case, however, when setting up Nightly the following night, please lower the sound volume.
If I wake up at night, should I restart the app?
If you accidentally wake up, it is not necessary to restart the app. You can, however, play the falling asleep sounds again to help you get back to sleep by choosing the replay option.
Will Nightly help me with lucid dreaming?
No, Nightly isn’t designed to induce lucid dreaming. It does, however, provide you with the place to write down your dreams, which can be quite helpful in the matter.
Are there any specific situations in which the Nightly app should not be used?
There were no specific situations reported or discovered by Nightly users or by the Institute of Psychiatry and Neurology in Poland where the app was tested. However, if you observe any disturbing effects connected with using the Nightly app, we recommend to immediately stop using it and contact us: email@example.com
If you experience troubles with sleeping, you should first contact your GP.
Why is high-quality sleep so important?
Sleep is associated with most of our vital functions. When you sleep, hormones responsible for crucial life functions, such as the growth hormone, serotonin, prolactin and many others are secreted. Also, memory consolidation, tissue repair, and the removal of neurotoxins from the brain take place when you sleep. A good night’s sleep ensures that all these activities can be fully performed. Sleep is responsible for the functioning of your cardiovascular system, immune system and for the performance of our cognitive function. So, if you want to be more productive, avoid diseases and just feel better, you should make sure that you sleep well.
How long should I sleep?
The National Sleep Foundation research shows that an adult person should sleep 7-9 hours. The need for sleep also changes with age. But of course, the required length of sleep is a very individual matter: some people function great sleeping 6 hrs while for others that would be way too little.
What are the results of sleep deficiency?
Sleep deficiency, in the short run, affects emotions – we get irritable and grumpy. The risk of making an irrational decision or having an accident is increased, we feel more stressed, and our cognitive functions are impaired. In the long run, lack of sleep is extremely dangerous: it increases the risk of heart disease, stroke, obesity, diabetes and lowers fertility.
What are the symptoms of sleep deficiency?
You should pay special attention to the following signs, because they may mean you are sleep deprived:
- You feel hungry most of the time
- You feel more impulsive
- You’ve gained weight
- You have problems with your memory
- Making decisions is difficult
- Your motor skills are slower
- You feel emotional and unstable
- Your immune system is weak
- Your eyes get exhausted rapidly
- Your skin looks unhealthy
- You feel worn out and fall asleep during the day
What is the REM phase?
The rapid eye movement (REM) sleep phase is a sleep phase characterized by rapid movement of the eyes, low muscle tone throughout the body and vivid dreams.
