Nightly watches over you while you enjoy healthy undisturbed sleep. Our Sleep Stimulation technology actively detects critical moments in the night and reacts with soothing audio to help you get an entire night’s rest uninterrupted by bad dreams and unwanted awakenings. Nightly also offers all the other essential sleep functions that you would expect from a sleep assistant app which help you understand and develop an overall healthy sleep habit.

Nightly is recommended to people who would like to alleviate certain sleep problems and develop and maintain a healthy sleep routine. The app was created to help people suffering from frequent bad dreams and unwanted awakenings. A precise sleep tracking mechanism combined with Sleep Stimulation help create an environment conducive to healthy, undisturbed sleep.

  • Set the alarm.

  • Watch the short relaxing video.
  • Lock the screen and place your phone on your bed next to the pillow.
  • Enjoy your sleep with Nightly.

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.

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.

All devices with iOS 10 and higher and Android 6.0 and higher.

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.

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.

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.

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.

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:

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.

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.

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:

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.

After downloading the app, you receive 14 consecutive nights of a free Nightly trial. You can purchase a subscription by clicking ‘Unlock full access’ option in the main menu. You can also do it in the iTunes Store.

The subscription gives you unlimited access to all the app’s functions including all the Relaxing Themes and statistics about your sleep.

After the 14-day free trial, you can choose a monthly subscription of $4.99 or a yearly of $39.99.

The free trial lets you experience all the benefits of Nightly. For 14 consecutive nights, you can use the app to fall asleep easier, improve your rest and use the Intelligent Alarm to make your mornings smoother.
The trial version includes a choice of Relaxing Themes that will help you unwind and improve the efficiency of your sleep. It also gives you an insight into your sleep statistics and lets you evaluate your sleep in the short term.
To continue enjoying your Nightly experience, you can simply purchase your subscription using the ‘Unlock full access’ option in the app’s menu or through the iStore.

Within the 14-day free trial, you receive access for 14 days in a row. This means that as soon as you use the app for the first time, the 14-day trial clock starts ticking and will end 14 days from that moment, regardless whether you use the app every day or not.

You can get a monthly or yearly subscription. Any subscription renews itself automatically.

One Nightly subscription is connected to one profile. You can switch the profiles within the app, but it works only for one person at a time.

All the audio-visual themes are scientifically designed and tested to help you feel relaxed. However, everyone is a bit different, that’s why there is a choice of 14 so that you can pick the one that suits you most.

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.

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.

The number of stimulations may vary each night. Usually, it turns on several times.

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.

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.

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.

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.

Yes. As a matter of fact, we recommend to lock it.

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.

It should not happen. If that’s the case, however, when setting up Nightly the following night, please lower the sound volume.

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.

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.

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.

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.
