Help us improve HRV-based respiration: $1 credit per qualifying activity

We’re looking for athletes who can record activities wearing both a Tymewear sensor and a Polar H10 or Suunto HRM at the same time. Yes, two chest sensors simultaneously. We need paired data to keep improving the HRV-based respiration frequency algorithm under real-world conditions, see recent blog post

The system automatically scans new activities synced from Garmin. Any activity that contains both direct RF (Tymewear) and HRV-based RF with artifact correction below 5% earns a $1 credit to your AI Endurance account, applied automatically. Just wear the sensors and let Garmin sync as usual.

If you have a Tymewear and are willing to double up on chest straps for some of your rides and runs, we’d really appreciate it. More paired data means better RF estimates for everyone.

Hello, is this study still open?

yes still open
