On-device stress tracking for Apple Watch.
Calmline reads your HRV from HealthKit, scores it against your own rolling baseline, and surfaces a Smart Stack card that promotes itself to the top of the stack exactly when stress is high.
A haptic-guided breath is one tap away, right on the wrist, the moment you need it.
Nothing leaves the device — the scoring, the history, all of it stays on your Watch and iPhone.
A card that rises to the top when your stress does.
Guided breathing one tap away, no phone needed.
HRV scoring and history never leave your devices.
