5/5Finally can sleep…
I’ve been using NuCalm regularly for about 4 years now and when used consistently and as directed (for the Rescue tracks you need to use a light blocking eye mask and good quality headphones, preferably noise-cancelling ones) it’s an incredibly powerful system to bring calm to the nervous system and healing to the body. It has given me the ability to sleep solidly through the night after years of sleep troubles due to severe chronic stress and is something you just need to try to experience it for yourself. I actually really disliked using this when I first started using it because my body was so wound up due to the years of stress but I stuck with it and after about 6 weeks of consistent use began to notice changes with overall being more calm and present during the day and then being able to sleep throughout the night. Prior to this I was only able to sleep for 3-4 hours at a time. I now look forward to my daily Rescue session, it’s like a vacation from the harshness life can bring to us all. The Focus and Sleep tracks are great too but the Rescue tracks are what have personally impacted me the most. This company is legit and sincerely wants to help people have a better quality of health and life and I applaud them for their contributions to help humankind in such a needed way!

5/5Deepest Sleep+ -- This Is the Track That Fixed My Nights!
I've run the full NuCalm protocol daily for a long time now -- Ignite, Priming, Rescue, Focus, Flow State -- and Deepest Sleep+ is the one that changed my life the most. Since I started using it, I've had record-breaking contiguous sleep blocks (any man over 50 who's up two or three times a night knows exactly why that matters). Full nights, no fragmentation. That's not a small thing -- that's the whole game. And it doesn't stand alone. The Ignite sessions are my daily engine -- on the days I don't want to train, one track in, two at the absolute most, and I'm launched. Ready to go, no debate with myself required. The new 40-minute Rescue VT is its own kind of miracle -- it's the rest-equivalent of two hours of sleep. Doesn't replace the sleep. Doesn't need to. It gives your nervous system what it needs when the clock won't cooperate. Between Deepest Sleep+ rebuilding my nights and Rescue/Ignite carrying me through the days, this isn't a wellness app to me anymore -- it's infrastructure. NuCalm built something real here bc there’s no part of my life the app doesn’t impact.

1/5Bad pricing, app, website, and customer service
Things were great in the beginning and then this new change came. Ive had endless complications trying to communicate with customer service and whenever i did it was one guy named “Bob” he made things harder than easier for me. This process should be simple and “relaxing” as stated. Im not sure if this company really has peoples best interest in mind to be honest. Its ashame because the system it self is really great but the app, website, and customer service absolutely put a bad cover on the company’s name. The new website makes it extra hard to find what your looking for and when you do the prices are through the roof. Ive NEVER delt with such bad customer service before leaving numerous emails and phone calls to be left frustrated without what i need (i get better customer service calling airlines if you can believe that). I was told i would have my neuro acoustic software until the 15th of this month and got lied to. I have 4 discs left so i needed that time the app told me i had left. I wasted a disc today thinking i had time left on the app! What a hoax… The company was doing good until all this change started to happen the app didn't look old school, website was working ok, and there wasn't any serious complications. Im genuinely sad and feel slightly abandoned due to the fact that ive found something that works for me and have no way of getting help navigating the best way to go about the system. Thanks for a stress free experience nucalm! (Not)

5/5Really helped me during the hardest time of my life
My dad was just diagnosed with cancer, my mom just had 2 heart attacks. And I had basically just been ghosted by someone I loved more than I could ever explain. We were together for a long time and it literally rocked my whole world and everything was falling apart. I needed every bit of help I could get. This system was really good for getting me up and out of the house and even exercising, which really helped my mental health. I’m grateful for their participation with Tony Robbins, as well, and deeply grateful to him, more than I could ever explain. When you lose someone so suddenly that you think you’re going to spend the rest of life with, for reasons they never even explained, that leaves a wound deeper than some of the worst trauma that I’ve ever experienced, and I’ve experienced a lot, growing up as an “at risk” youth. I’m grateful I “made it out” and part of that was never turning down any tool that could help. This is a tool that helped.

5/5Life, saving and magical
I’m a dentist and I use Nucalm to relax my patients. I used Nucalm myself during sleep for the first time to relieve a lot of stress I’ve had in recent months. I tried the deep sleep session and I was incredibly amazed at how vivid my dreams were. I had dreams of my mother and brother who passed and they were so real that when I woke up, I was literally in tears. The main reason I started using the app was because I had uncontrollable high blood pressure. When I woke up from just that one session, my blood pressure was normal. I’m using the deep sleep session every night now. I would have to say it’s life-changing because stress and high blood pressure will eventually take your life and Nucalm has actually lowered my blood pressure when medications didn’t work. The icing on the cake is better a better quality of REM sleep which is where all the magical dreaming happens!

3.2.3
This update includes: - playback bug fixes and performance improvements related to the iOS 26 release.
3.2.4
Release 3.2.4 includes the following new features: Stress Test: the new Stress Test features revolutionary voice-analysis technology that evaluates over one million data points from a 35-second user recording and provides a coherence score on a scale from 1-100 (1 = low coherence and 100 = high coherence). This coherence score is an accurate measurement of the user’s current nervous system balance and resilience. The Stress Test is best used before and after NuCalm Rescue sessions to evaluate the impact NuCalm’s patented stress relief neuroacoustic software has on improving your nervous system balance. New Neuroacoustic Products: this release introduces three new NuCalm products – DeepestSleep, DeepestSleep+, and Priming. DeepestSleep is another leap forward for improving sleep quality by advancing upon the proven DeepSleep physics. The precise signals in the neuroacoustic software underneath the music gently guide brain wave frequencies to deep delta (0.5Hz) to help people fall asleep faster, sleep deeper, and stay asleep longer. The DeepestSleep+ adds the brilliance of NuCalm’s most powerful Rescue tracks to help you unwind and slow down your brain so you can ease into sleep at bedtime. Priming is designed to elegantly increase the frequencies of your brain into the high clarity state of gamma (40Hz) and include world-class collaborations with Tony Robbins, Jim Kwik, Roger Love, and Madison Emiko Love. One-Click Cancellation: our mission is to reduce stress. This release features a one-click cancellation feature in the app so anyone can cancel without stress – no AI bot loops, no frustrating searches, no surveys, just one-click to cancel.

What a hoax… The company was doing good until all this change started to happen the app didn't look old school, website was working ok, and there wasn't any serious complications. Im genuinely sad and feel slightly abandoned due to the fact that ive found something that works for me and have no way of getting help navigating the best way to go about the system. Thanks for a stress free experience nucalm! (Not)",

We were together for a long time and it literally rocked my whole world and everything was falling apart. I needed every bit of help I could get. This system was really good for getting me up and out of the house and even exercising, which really helped my mental health. I’m grateful for their participation with Tony Robbins, as well, and deeply grateful to him, more than I could ever explain. When you lose someone so suddenly that you think you’re going to spend the rest of life with, for reasons they never even explained, that leaves a wound deeper than some of the worst trauma that I’ve ever experienced, and I’ve experienced a lot, growing up as an “at risk” youth. I’m grateful I “made it out” and part of that was never turning down any tool that could help. This is a tool that helped.",

          "body": "I’m a dentist and I use Nucalm to relax my patients. I used Nucalm myself during sleep for the first time to relieve a lot of stress I’ve had in recent months. I tried the deep sleep session and I was incredibly amazed at how vivid my dreams were. I had dreams of my mother and brother who passed and they were so real that when I woke up, I was literally in tears. The main reason I started using the app was because I had uncontrollable high blood pressure. When I woke up from just that one session, my blood pressure was normal. I’m using the deep sleep session every night now. I would have to say it’s life-changing because stress and high blood pressure will eventually take your life and Nucalm has actually lowered my blood pressure when medications didn’t work. The icing on the cake is better a better quality of REM sleep which is where all the magical dreaming happens!",
