Unable to download the latest update on iOS 15 Pro
Unable to download the latest update of the App. Tried deleting the app, restarted the phone multiple times and different networks with no success.
Update broke the app on Day 2
I only got to use Lief for 1 day before version 8.1 bricked it. Now it’s stuck on the pulsing screen and won’t connect on either iPhone or Mac. Please fix ASAP — I’ll update this review once it works again.
Difficult to Connect
I like the Lief device when it is working. However, most of the time there is connectivity problem. A friend also has the same problem with Lief. Customer support is not much help.
Not reliable for the $$
When you pay over $230 for something you expect no problems. The self pacing doesn’t work 1/2 the time (the buzzing). The HR/HRV meter seems to work fine.
Awesome HRV-B device
This is the only wearable that’s taught me what to do to raise my HRV. The Downtime breathing has really helped me learn to regulate my nervous system and learn what my stressors are and how to work through them.
