### 4/5 — Program good. App…Meh

*2026-05-28, version 3.2.6*

I like the content. Good program. The app is behind. Lots of connection issues and doesn’t work with earbud commands. IE start, stop by pressing ear bud.

### 3/5 — Content is Good, App is Not

*2026-04-24, version 3.2.6*

I love the content of the app when it operates well, but I am struggling to say I like it. So far, the two nights I’ve tried it, the Deepest Sleep+ has been revolutionary. Also, the two nights I’ve used it I hit the wrong sound/time frame and had to delete the app and reinstall it for me to be able to exit out of the wrong choice. BRUTAL. If the product itself weren’t so helpful I would have already canceled and never looked back.

### 3/5 — Music can be activating

*2026-04-01, version 3.2.5*

Though I am enjoying many of the products from new call some the music is too loud - even at lowest level.    
The new Rescue VT 40 music is also activating for someone with PTSD.  
Disappointing it is told to us that much research has been done.     Attention to more detail would be appreciated including the app which hasn’t changed that much and doesn’t allow
For the client to properly track their progress.   
Feedback link doesn’t have a link for feedback ????

### 2/5 — Not worth it

*2026-03-31, version 3.2.5*

It works okay. Overrated and not worth the cost. If it were less of an investment I would have kept it.

### 3/5 — Overpriced

*2026-03-24, version 3.2.5*

I’m updating my review.  The developer reached out to me with the concerns I had in my 1 star review.  The tracks actually do work very well.  They are just so strong I had a very unsettling experience the 2nd night I tried it.  I still think it’s overpriced.  I get similar results from brainwave products you can pay for once and own for life.

### 5/5 — Sporty

*2026-03-16, version 3.2.5*

In only one month this app had has a profound impact on my daily life.

### 5/5 — Game Changer

*2026-03-05, version 3.2.5*

I’ve used this for 6 years and can’t begin to describe how helpful this has been. I use it daily.

### 5/5 — Life Changing App

*2026-03-04, version 3.2.5*

This app is life changing! If you want less stress in your life you need this! If you want an unfair advantage in life get this app!

### 5/5 — Amazing!

*2026-03-01, version 3.2.5*

This app has improved my sleep quality immensely. Far better than any white noise you would find on YouTube. The other features also work incredibly well and the data is backed by real science. This app truly does work wonders couldn’t recommend it enough!

### 5/5 — Unbelievable

*2026-02-27, version 3.2.5*

Only been using the app for a week and the changes are remarkable!  My sleep is so deep and the racing thoughts in my mind have subsided. I haven’t felt this calm in years and I’m able to actually concentrate/focus and get work done without squirrel brain!

### 5/5 — 5 star

*2026-02-17, version 3.2.5*

App is easy to use and listen to often.   Nice variety too.

### 5/5 — Life Changing

*2026-02-10, version 3.2.5*

I have been using NuCalm for 5 years now and it has been an integral part of my rest, energy, focus, sleep and creativity. I’m able to do and accomplish more with my business and personal life completely drug free. My physical and mental health has never been better!

### 5/5 — LIFESAVER

*2026-02-09, version 3.2.5*

NuCalm has truly been an ABSOLUTE LIFESAVER! I was at the end of my rope, but now I have a lifeline, especially with Rescue VT, PowerNap, & Flow-state! 🙏🏼, 🙏🏼, 🙏🏼 for developing & making this software available!

### 5/5 — The Ultimate Nervous System RESET - Relaxation & Focus & Energy on a completely new level !!!

*2026-02-03, version 3.2.5*

After 65 years along came Nu Calm - A Game Changer for ones nervous system who ever you are in life - Nu Calm was highly recommended to me by a friend - Signed up for the free trial - 3 monthly subscriptions later - Signed up & paid for the year - 6 Months in & just paid however many thousand dollars for the Ultimate Nu Calm Subscription - Mastermind 2.0 - I guess that says it all hey - So let's discuss the discs - A friend introduced me to the discs & I was very sceptical - Now I would not-not have a disc on my inside left wrist 2cm in from the wrist hand line at least 6 days out of 7 days - Let's just say if it is not on my wrist I know it instinctively !!!

## Most critical reviews (10 lowest-rated)

### 1/5 — Not worth it

*2026-06-13, version 3.2.6*

I’ve had it for a few months. The app on phone doesn’t work well. Zero customer support. Haven’t noticed a positive or negative effect from using the programs.

### 1/5 — Frustration

*2026-06-08, version 3.2.6*

It is so god damn buggy, I just get tired of trying to use it

### 1/5 — this version has issues

*2026-05-11, version 3.2.6*

I am unable to stop the sleep module once started.  Even turning my ipad on and off will not get me out of the sleep mode.

### 1/5 — Scam

*2026-04-05, version 3.2.5*

Tried to cancel and there was a convenient glitch in the software.

### 1/5 — Be aware

*2026-03-16, version 3.2.5*

Very bad customer service; never received verification email despite numerous attempts over a weeks time to reach out to someone. They charged my credit card immediately but I was never able to login. Still to this day, no one has reached out to me.

### 1/5 — Sleep

*2026-03-10, version 3.2.5*

I read through all the literature and then chose what they recommended … a seaside and possibly crickets…? An hour later, I thought I’d better turn it off because it was early morning and I needed to sleep. But unfortunately I couldn’t sleep until about 0500 so it did the reverse of what it promised… I’m not impressed because I had planned to get up earlyish but had to turn off the alarm and ask my husband to let me sleep in! So I’ve wasted some time already - AGAIN

### 1/5 — App design is cheap and limited

*2026-01-21, version 3.2.4*

Make a better app already…it used to be great, but now the app functionality is so limited they remove tracks to add new ones and pretend they do this for your benefit.  Support staff is horrendous, the head guy is overweight and pontificates about whats best for your health, what a joker.

### 1/5 — Please do your own research as the claims are not scientific

*2025-12-21, version 3.2.3*

I tried NuCalm after it was presented to me as a science-backed solution for anxiety, nervous-system regulation, and improved sleep. The claims sounded especially compelling given how vulnerable people with chronic sleep issues can be. I did my own research afterward, and here’s what I found.

Key takeaway:
NuCalm shows evidence of short-term relaxation, but there is no strong scientific evidence that it produces deep sleep or replaces hours of restorative sleep, despite marketing claims that suggest otherwise.

What the research actually shows
NuCalm frequently cites “Harvard research.” What appears publicly available is a company-branded research summary, not a peer-reviewed sleep study.

The data focuses on:
-Autonomic nervous system markers, such as heart rate, respiration rate, and heart rate variability (HRV)
-Indicators of parasympathetic activation (often described as “vagal tone”)

These measures can demonstrate physiological relaxation — meaning the body is calmer.

Important distinction:
Relaxation doesn’t equal sleep.

The studies cited do not measure:
	•	EEG brainwave activity
	•	Sleep stages (N1, N2, N3/deep sleep, REM)
	•	Polysomnography or validated sleep architecture outcomes

Without these, claims such as “20 minutes equals 2–4 hours of deep or restorative sleep” are not scientifically supported.

### 1/5 — Ugh

*2025-12-10, version 3.2.3*

Wish it had a more modern and seamless interface.. super slow and unnecessary pauses in between actions…. I was sold on a soundtrack that I am not finding anywhere in library

### 1/5 — Not working

*2025-12-04, version 3.2.3*

I can open the app, but when I select a program the app shutters and then asks me if I’m done or want to repeat.

## Most praised reviews (10 highest-rated)

### 5/5 — Literally saved me

*2026-08-14, version 3.2.6*

PTSD and nightmares. Nothing calmed me except for sedatives, until I found NuCalm rescue. Amazing resource

### 5/5 — Deep sleep

*2026-08-14, version 3.2.6*

I am using the sleep suite it’s fantastic to work with all other bio hacking mechanisms

### 5/5 — Deepest Sleep+ -- This Is the Track That Fixed My Nights!

*2026-07-30, version 3.2.6*

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.

### 5/5 — Game changer

*2026-07-17, version 3.2.6*

Getting enough sleep can be a challenge at times. NuCalm’s rescue is amazing. On those days when I’m dragging a 20 or 30 min session is absolutely amazing. I feel reenergized. It really is a game changer for life.

### 5/5 — Really helped me during the hardest time of my life

*2026-05-29, version 3.2.6*

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.

### 5/5 — Best App for Sleep

*2026-05-26, version 3.2.6*

We have used NuCalm for years. Nothing helps me get into a deeper sleep fast. Oura ring can confirm the sleep data. 10/10 recommend. The customer service is also excellent if you have any login issues.

### 5/5 — Wow ! This is the best sleep I have had

*2026-05-05, version 3.2.6*

Great app ! I have not slept this well or deep in 9 years ! It’s worth every cent ! No pills , no ordering anything else unless you want to order a mask and head phones .

### 5/5 — TBI, pain management, insomnia, trauma management

*2026-04-19, version 3.2.6*

A fellow veteran encouraged me to use NuCalm for several combat related and personal injuries. Prior to use, I was primarily struggling to keep my cortisol levels and spikes under control. I tried all kinds of methods, diets, nutrition/ supplements, and medical interventions that help but not actually keep it consistent and manageable. I quantitatively noticed through bloodwork and overall have a better wellbeing and mental clarity with consistent daily use; that this system works. Not related but I have been recently incorporating IR light and frequency/ harmonics to stimulate and heal damaged nerves and tissues. I will live with pain for the remainder of my life but have eliminated any need of pain medication recently.
