About

Calmgraph turns your daily stress into one number you can actually act on - fully on-device, no subscription. - Stress score (0-100) From Apple Watch HRV, resting heart rate, and sleep, measured against YOUR personal baseline rather than a single absolute value. The first 14 days are a calibration period shown as provisional. - Cause tags Tag work, sleep, exercise, caffeine and more, layered onto your score so you can see what may have moved it. - Weekly insight See what likely moved your score each week. These are correlations, not conclusions. - No Apple Watch? No problem Quick 1-tap check-ins give you the same visualization. - One-time purchase, not a subscription. All measurements are processed on your device. Nothing is sent off-device, collected, or used for advertising. Calmgraph is not a medical device and is not intended to diagnose or treat any condition. Consult a healthcare professional about any health concern. Pro: Widget · Breathing guide · Export.
