Calm - Heart Rate & Breathing

You check in with your body in minutes: measure pulse using your phone camera, follow guided breathing sessions, and see simple trends over time—without turning heart health into a chore.

Guided breathing: Structured sessions (including box‑style pacing) designed to help you downshift stress and wind down before sleep. Trends: Track patterns like resting heart rate direction so changes feel meaningful—not noisy single points. Built for privacy Your readings and activity stay on your device.
