Launching soon!
Hey - How is AI involved in making me sleep better? I don't understand that part...thanks

Launching soon!
also, can i lock my phone's screen/switch screen off while the app runs or does the screen need to remain on at all times?
Lukasz Mlodyszewski
@orliesaurus hi! Sure, happy to answer :-) In order for the app to detect the right moments during sleep to stimulate your sleep (ie - stimulating during light sleep stages would wake you up) it's using multiple algorithms classified as AI to learn how you sleep and adjust to that. It's even capable of adjusting to your mattress hardness. We've used a ton of clinical (PSG) data to create it (actually, a lot more than most of medical grade devices) and then adjusted using real-life usage data we've gathered during the last 2 years. As for the screen - yes, you can switch the screen off!

@orliesaurus no prob! happy to help and please let me know if you have any other questions! :-)

@lukasz_mlodyszewski How does this handle people who sleep next to a partner? Is this only compatible with single people?
Lukasz Mlodyszewski
@ecwilson Apologies for the delay - just noticed your question. We've tested it extensively internally and we have many users who don't sleep alone use the app and report it's working great. The app is being able to an extent adjust and isolate secondary movement, especially on firmer mattresses. Interestingly, cats seem to be a bigger problem when it comes to interfering with tracking! :-)

Great app especially for professionals who have trouble sleeping. Highly recommended

How does this differentiate from other sleep apps other than a good design? Also need Apple Watch app.
Lukasz Mlodyszewski
@haoyangnz hi Haoyang, Main difference is - we're not just a tracker - we're using Sleep Stimulation technology which is using audio-visual stimuli and advanced AI algorithms to help you sleep better. This is both based on existing research, but also, our last 4 years of research. As for the Apple Watch - I agree - however, from battery management perspective, it's not actually easy. Most - if not all - sleep trackers only process the data in the morning. For us, in order to simulate at the right moments, we need to process it in real time... which drains the battery. We'll definitely look at it again in the future.

It's not some tracker bul***it app. This one is science based and actually works
Konrad Kobiela
At first i was like.... ohh just another sleep tracker type app but it is a lot more. You need to use it once to understand the difference.
Thomas TomHawk Burningham
Fascinating. What about the effects of bright light, especially blue light from your phone at night?
Lukasz Mlodyszewski
@thomas_tomhawk_burningham hey Thomas, it's a question we often get :-) It's a truly tricky subject - firstly, most of the research into the subject is done over a long exposure of a couple of hours before sleep. Nightly requires less than 3 minutes of usage, so the effect on melatonin is minimal - on top of it, we encourage everyone to use night-shift and lower brightness at night to mitigate the issue further. Then there is what people really do - a lot of our users and patients have trouble falling asleep and often end up browsing social media or playing games... Nightly helps them fall asleep instead, so, that's definitely a plus :-)
Giampaolo Falqui
How would you compare Nightly with Sleep Cycle?
Lukasz Mlodyszewski
@gfalqui hi Giampaolo, The major difference between Nightly and other sleep trackers is that we're using Sound Stimulation technology which is using audio-visual stimuli and advanced AI algorithms to help you sleep better. We're also doing a ton of research into sleep - for example, we've just recently finished a registered clinical study in sleep lab (randomised, double-blind /w crossover) to check our algorithms accuracy and check the effects of Sound Stimulation. The results are amazing and we're just writing up the research paper and will be sending it for peer-review soon.

@gfalqui @lukasz_mlodyszewski It's great to see a company like your actually take the proper research routes. Bravo!

Not only a beautiful product - a well-designed app with enchanting videos, but also research backed. Good combination.

Hello Product Hunt! March 16th is also known as World Sleep Day. We would like to take this opportunity to give you a 21-day free trial of our app, Nightly. Nightly is an AI-based technology that works actively to help you enjoy healthy, undisturbed sleep. It keeps your night restful in three ways: it helps easily fall asleep, limit bad dreams and reduce the likelihood of nighttime awakenings. It watches over you throughout the night to help you start your day refreshed and full of energy. We’ve been working closely with psychologists and scientists to transfer years of lab research into a mobile app. The fruit of this cooperation is our unique technology - Sleep Stimulation. It’s a combination of two factors: audio-visual stimuli and advanced AI algorithms. Nightly monitors your sleep live, recognizes critical moments during your night and reacts with soothing sounds to help you minimize the possibility of a wakeup. It stimulates your sleep to help you keep your rest uninterrupted. I would love to hear your feedback!

@lukasz_mlodyszewski Nightly goes head on with my insomnia arsenal: Audioteka, Audible and Storytel ;) Very attractive app design and impressive tech underneath.
Lukasz Mlodyszewski
@blazej_os and we're just getting started! Some sort of story-telling module is something we might look into in the future. Who knows, maybe in a collaboration with one of those companies? :-)

Been a huge Sleep Cycle fan so I'm going to have to check this out!
