Most Frequently Used App
As a professor, an author, and a consultant, maintaining balance and focus are key to me. A full night sleeping is pretty important, too. I find myself using this app multiple times throughout the day to help with my productivity and at night to help with peaceful sleeping. It has become an critical component for helping maintain my productivity levels.
I have never write a review and felt compelled to tell you this app is incredible. After the first two nights of sleeping with A2A I woke up more calm and remained that way for a lot of the day. The hibernation setting is great for chilling at night before bed. Then switch to the sleep setting. It is really weird to me that this is able to have such an impact on my actual life just using sound. 🤩
Helps with my ADHD brain and insomnia
All I can say is – wow. I used the app for the first time last night after really struggling to sleep, saw the ad and downloaded it (I usually ignore ads but for some reason the ad on this app really caught my pique). I love how minimal but unique the application is. The moving patterns are beautiful as well. I managed to sleep immediately yesterday and I actually played it throughout the night and had a wonderful night sleep. It helped calm my racing thoughts at night and I was surprised at how easy it was to fall asleep.
Helps with my ADHD brain and insomnia
I initially got this for background noise while working but now it’s one of my most used apps. If you have ADD you know the struggle of hating silence but also finding most music/podcasts to be too distracting or hard to listen to. I used to listen to classical music but this is SO much better – just set it and forget it and it’s so peaceful and pleasant to have in the background. Now I use it to sleep, alarm wake up, chores, my morning/evening commute – I recommended it to my therapist and she loved it so much she is now recommending to her other patients! Can’t thank the developers enough, it’s worth every penny!
I have always had a hard time sleeping, and with me being anemic it makes it harder, and the first time I tried this I had such a good night of sleep! I woke up even before my alarm! I recommend it to anyone and everyone! This app works miracles!
I’m speechless
I’m diagnosed with borderline insomnia major depression etc Nothing really helps me to relax focus clear my mind or sleep. But this app is making me more than happy. I’m so grateful thank you so much guys!!
Best sleep ever
I have never taken the time to write a review until now. A2A is a life changer. The sounds are so soothing and can put me in the most relaxed state and help me fall asleep so quickly and easily. I recommend this app all the time to people, especially ones who find falling asleep difficult. Thank you, A2A, I truly love you <3
I absolutely love this app I’ve been using this app for the last 5 years, to help me get better sleep at night. The more they improve this app, the more I love it. “AI lullaby sets me off to sleep with gentle, soothing tones that help blend the background noise into something a little softer. It’s my most used app, and my most important app. Thanks A2A:)

FAQ
What is the difference between Soundscapes and Scenarios?
The Endel app has two main forms of audio content — Soundscapes and Scenarios. Soundscapes are endlessly generated on the device following your local inputs — weather, time of day, cadence of your walks, and heart rate (if you’re wearing your Apple Watch), and others.Learn more about the inputs.
Scenarios are sound sessions with predefined logic (initial, middle, and end phases are defined and pre-generated for the timer you set). They are designed to be used for a particular task or life occasion in a timed session.
Is A2A sound tuned to 432kHz?
The Endel’s sound is tuned to 440 hertz. It’s the so-called natural order, where the relationships between the intervals are as simple for the brain to process as possible. According to research, it helps reduce the cognitive load in perceiving musical information.
Does A2A use binaural beats?
There is a Binaural Beats Scenario in the app. The other sounds don’t use this technology. Binaural waves at the physical level work exclusively in stereo headphones, make sure you wear them when you use the Binaural Beats Scenario.
I need help with A2A. How can I get it?
If you have any issues with the Endel app function or with your subscription or have any questions about Endel, you can contact our support via a form in the app or by reaching out to us: [email protected].
Why do I need to buy a subscription for A2A?
Paid subscription model is a necessary format for us to keep maintaining and developing Endel continually. The subscription price includes our work on updates — not only do we fix bugs and improve our products’ technical performance gradually, but also consistently add new sounds, features, and user experience improvements, based on user research and with the best interest of the Endel community in mind.
Do I need to follow the circadian and ultradian cycles?
The circadian and ultradian cycles are scientifically backed theories of daily energy levels. In an ideal situation, it would be advisable to follow the rhythms: rest on low phases, and be active on high phases of the cycles. But it is hard to accommodate in modern everyday life. Which is why the Endel app can also help you mitigate the negative influence of the cycles with sound.
For example, when you play Focus during a low period of the circadian cycle, you’ll notice that the sound is still stimulating for concentration, but not as intense and driving as during the highs, to help you ease into the work you need to do at that moment, instead of pushing you too hard.
How effective is A2A?
Millions of happy users and their feedback in endless reviews and messages attest to the efficiency of Endel’s sound. However, sound perception is a very subjective matter, and we fully admit that Endel may not work for everyone in the same way. We base all of our Soundscapes and Scenarios design on scientific research, and there is peer-reviewed research that backs the efficiency of Endel’s sound compared to playlists and silence. For more information on the science behind Endel’s sound, go here.
Is A2A scientifically proven?
All Endel Soundscapes and Scenarios are based on scientific research around sound, neuroscience and Circadian science, and there is a peer-reviewed study that backs the efficiency of Endel’s sound compared to playlists and silence. For more information on the science behind Endel’s sound, go here.
