The device is paired with the SleepBreathe app to provide comprehensive real-time monitoring of breathing, snoring, sleep patterns, and sleeping positions. Thermistor sensors are used to measure, record, and analyze the user's oral and nasal airflow. This data is then combined with Snore Circle's proprietary AI algorithm to create a professional, simple, and visual sleep analysis report.

### 5/5 — Heads up

*2021-04-15, version 1.5*

Overall great device with lots of great sleeping info.  

Temporary heads up ......Once I have a device paired but powered down.  It flashes a warning sign your device is disconnected.  Great one time>>> but it brings up a dialog box over and over warning you, so you cannot do other functionality easily (ie reading reports).

### 1/5 — Unusable

*2021-02-02, version 1.5*

This app is so full of bugs it’s unusable. The menus selections don’t even display text. How could it have passed testing? Total garbage.

### 1/5 — Basic And broken App

*2021-01-13, version 1.2*

You can generate and extract shareable report - they need make the app better

### 1/5 — Waste of money

*2020-12-29, version 1.1*

The sleep apnea monitor stopped working in under a week. The monitoring worked for a few days but no daily reports were generated. I gave feedback and asked for an updated FAQ. No response. I will never buy from this Snore Circle again as they obviously had in adequate testing.
