We’ve made it easier to monitor your HRV in real time, practice Downtime, and track your progress. The new version enables you to take screenshots of what you’re seeing on your app and share them with your Coach, if you’re working with one. Below, we share a preview of the key features of the revamped app. We invite you to share your feedback after trying out it out.

Home screen

Instead of the chat box, the home screen now emphasizes your real time HRV and BPM, and your color zone, so you can see how you’re doing at a glance.

Lief mobile app

Tap on the big circle with your HRV number in the middle to see your overall Downtime practice stats expanded:

Clockwise from the top:

  • Your average HRV change after participating in a Downtime practice
  • Your overall success rate (i.e., how often did you increase your HRV after participating in a practice session?)
  • Your current HRV
  • Your average time to complete a Downtime practice session

HRV timeline

Your HRV timeline is still at the top. Similar to before, each bar represents your average HRV for that 5 minute period. We’ve simplified the appearance of the timeline to help focus your attention on the present moment. To see the color zones, simply tap on the timeline.

Downtime practice session

To initiate a practice session through the app, tap on the blank white circle on the bottom of the screen. You can choose however many minutes you’d like to practice. Generally, 3-5 minutes is an effective length of time to increase your HRV.

The Downtime practice session has been updated to make it easier for you to see your real time stats, and whether you’re creating a wave pattern by syncing your heart rhythm and breath rate.

You’ll notice the menu at the bottom has changed. We’ll explain each of the changes below.

This new feature helps you take notes on how you’re feeling in any given moment. To tag your feeling, slide your finger up until you find the feeling that best describes you in that moment. The options from bottom to top are: Fatigued, Sad, Stressed, Anxious, Neutral, Alert, Excited, Happy, & Calm.

After selecting one of these options, you’ll have the opportunity to write a brief note. This is your chance to reflect further on why you’re feeling the way you do in that moment. You’ll be able to access all your past moments under the Progress button, which we describe below.


You can track your HRV and Moments data under this button. Similar to before, you can see your historical data, including your average HRV by day, your Downtime practice success rate, and wear time under the Progress tab at the top.

If you change to the Moments tab, you can see all the feelings you’ve tagged using the Moment button. These are date and time stamped, so you can remember how you were feeling on any given day.


The chat box is now accessible through the bottom menu’s “Chat” button. If you’re working with a Lief Coach, this is where you can chat with your coach, see videos they share, and respond to the prompts they share each week.

Sign-Out: Use this function to sign out of the Lief app if you want to sign in with a different email and password.
