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. ### 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 ### 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. ### 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. ### 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. ### 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. ## Frequently asked questions about NuCalm ### What does NuCalm do?

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.
