## Lief App Reviews in United States

### *---- "Annoying check in feature"
Of utmost importance with an app like this is convenience and usability. Every time you open the app it asks you to “check-in”.  The AI help and regular support failed to help me turn off this feature. Really annoying.
-- JayShares, 2024-12-24

### **--- "Buggy app"
The device itself is great but the app is incredibly buggy and currently I am unable to open it at all. Defeats the purpose of spending all this money on the device
-- Alex247789, 2024-09-29

### *---- "They have deactivated the cancel subscription button"
No way to cancel your subscription. The button doesn’t work. The only button in the entire app that doesn’t do anything when clicked. I’ve emailed support 3 times and just got charged $99 again. Criminal.
-- Tpain1239876, 2024-06-06

### ***** "Stress managed, thanks to Lief!!"
Lief is a great app that has helped me manage my stress levels. The app is easy to use and has a plenty of great features that’ve helped me track my stress levels, learning how to manage them. The interface is very intuitive and the app is very beginner-friendly. I love how the app provides personalized recommendations based on my stress levels and helps me find ways to relax and de-stress. I would definitely recommend Lief to anyone looking for a great stress management app.
-- octawvio, 2023-04-27

### ***** "First ever review for a app ever"
After a month of use this magical device. I have seen a huge increase in my daily battle with anxiety. One of the best decision I have ever made. Thank lief for making this life changing/saving device
-- Alwx_g_1989, 2022-09-09

### ***** "Best HRV biofeedback wearable I’ve tried"
After my therapist encouraged me to use heart rate variability biofeedback to help with my anxiety, I started using Lief bc it’s the only HRV wearable that provides real time feedback and automatic doses based on when my HRV dips. Best decision I’ve made. I’m able to calm myself down more effectively whenever I need. Coach was great too.
-- Chilosopher, 2022-09-08

### ***** "Really helps with my daily stress levels"
I’ve been using this app for a few months and it’s been instrumental in getting me through some really tough spots in my life where stress has been high. I love how passive the device is, I don’t have to remember to do a breathing exercise or stop what I’m doing, I just get pinged exactly when I need it. I could even be in a meeting and I can just do the breathing exercise passively since the device vibrates under my shirt. The app sometimes has some connectivity issues and is a little buggy, but I’ve been noticing it getting better, and it hasn’t gotten in the way of reducing my stress.
-- Dued711, 2022-09-06

### ***** "Mindful HRVB app"
I’m new to HRVB and I think the app is great for getting familiar with what increases and decreases my HRV. It’s simple, easy to use and is a great reminder to breathe throughout the day when your body moves more toward a flight/flight response. Been using for a couple months and my average HRV has increased since then and I have a much stronger mind body connection. It’s been a great tool for me.
-- Ems SC, 2022-09-02

### ***** "This device changed my life"
As a bio-hacker, I’ve used many wearables. I love bio-metrics data as a means to monitor my health. What set the Lief apart was not only the the accuracy + efficacy (due to the clinical nature of the wearable), but also the critical benefit of having bio-feedback assignments delivered in real-time. It’s a more pro-active way to manage stress, and in this day and age, who doesn’t need that? While I greatly appreciate understanding my metrics from moment to moment, I have experienced even more meaningful benefit in employing their down-time breathing assignments each day. It’s done wonders for my anxiety and overall general sense of wellness.
-- SKT 12, 2022-09-01

### ***** "Highly recommend"
I love Lief for tracking HRV data! Highly recommend for anyone looking for a self regulation tool
