Stress and focus

The app reads subtle shifts in your heart rate and skin temperature – long before stress affects your work. It then offers a two‑minute breathing guide or a gentle nudge to stand and reset, keeping your focus sharp from morning meeting to final deadline.

Recovery and readiness

After a hard workout, the app calculates exactly how long your muscles and nervous system need to recover. It won’t just tell you to rest; it shows you when you’re ready to perform again, so you never waste a session or risk injury.

Sleep Quality

Your ring tracks deep sleep, REM, and overnight heart rate variability, but the app translates those numbers into one clear question: “Did your body actually recover last night?” You’ll see a simple sleep score and a personalised tip to improve tomorrow’s energy.
