User Reviews

NuCalm offers effective stress relief, improved sleep, and various soundtracks for different needs, praised by users including athletes and those with health issues. However, many report significant app stability problems, frustrating subscription management, and a poor user interface. The cost is high, and some users question its long-term value. While support responsiveness is sometimes positive, overall the app requires improvements in technical performance and user experience to better meet user expectations.

Pros

Effective in reducing stress and improving relaxation, with many users feeling rejuvenated and centered after use.
Helps improve sleep quality and supports recovery, as indicated by users tracking heart rate variability and sleep metrics.
The app offers a variety of soundtracks tailored to different goals like focus, sleep, creativity, and stress relief.
Customer service is responsive and helpful according to some users who had initial issues.
Users with chronic conditions like MS reported symptom improvement and find the app life-changing.

Cons

Frequent technical issues, including app crashing, freezing, music skipping or stopping abruptly, and glitches interfering with seamless playback.
Difficulties with subscription management such as problems canceling subscriptions and unexpected charges with unresponsive customer support.
Poor user experience and interface design, including complicated navigation, lack of intuitive controls, and excessive unnecessary features like large headers.
App's connectivity and playback functionality is limited; for example, requiring Bluetooth connection for external speakers and poor offline playback support despite files being downloadable.
High cost with questionable value for money, and some users feeling the app loses effectiveness over time or doesn't provide measurable benefits compared to alternatives.

Recent reviews

This App was a 4 star in the beginning. Some issues downloading and opening the large files ... regularly. Customer Service responded very quickly and was able to solve the problem... they were VERY responsive... All is Great and I love NuCalm, I use daily! A great addition to a healthy life.

2024 EDIT - Avoid this app and these people. It loses it's luster and effectiveness pretty quickly. I turned off auto renew and they still billed me. Customer service refused a refund, even though I responded to the charge same day so now I'm working with CC company. Overall, that app is alright. There are a lot of different options for different ways to utilize this tool. I give this 4 stars just because of the price. I can't personally tell the difference between this and other apps like this
