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 and calendar
Tag work, sleep, exercise, caffeine and more, layered onto your score. The calendar view shows a month at a glance, and you can tap any past day to fix its tags or check-in.
■ Weekly insight and tag correlations
See what likely moved your score each week. The Pro correlation report compares your average on days with a tag against days without it, and always shows the sample size. These are correlations, not conclusions.
■ Apple Watch and widgets
The Watch app and complication put your score on your watch face and let you check in from your wrist - free. Home and Lock Screen widgets are part of Pro.
■ Breathing guide and reminders
A 1, 3, or 5 minute breathing guide for the days that sit in the strain band. Daily logging reminders and a weekly review notification are optional.
■ One-time purchase and backup
Buy once instead of subscribing. There is no cloud sync, but you can export a backup to a single file and restore it on another device.
■ Monthly & yearly summary / Weekly history (Pro)
Averages by month and year, with the calm / mixed / strained mix. Past weeks with their average and what was moving your score.
All measurements are processed on your device. Nothing is sent off-device, collected, or used for advertising.
