After trying multiple sleep tracking and HRV solutions I stumbled across the Emfit QS. In the hope to combine HRV readings, reliable resting heart rate and sleep tracking, I order the device.
If you are into self-quantification and want to monitor your recovery status (like me being a triathlete) this device is great.
After setting it up and connecting it to the Wifi, this device is very much hands off. It detects when you go to bed and automatically syncs your data. You can access your data via their online platform. I am always excited to review my sleep data the next day. This tool has been a valuable addition and made heart rate and HRV measurements in the morning obsolete.
