- **Real heart rate variability.** With SDK 4.33's HRV support, the calm
score and the per-session coaching line now factor in RMSSD (the
variability between successive heartbeats) when the watch's sensor
delivers it, on top of completion, heart-rate drop and breath-linked
swing. Without an HRV reading, the score falls back to exactly what it
did before.
- **Touch on the history menu** now uses the watch's own touch navigation
(SDK 4.33) instead of doing nothing — tap and scroll work like every
other menu on the watch.
