Description
Log a migraine in under a minute. See your real triggers. Export a doctor-ready report — while your health data stays private on your device.
Calmgrid turns scattered attacks into a clear pattern: what set them off, what helped, and what to tell your doctor.
Free: • Attacks per week • Severity distribution • Duration averages • Weekday patterns
Pro: • Top triggers ranked • Top symptoms ranked • Medication effectiveness breakdown • Time-of-day analysis • PDF export for doctor visits • Custom date ranges
Your migraine data stays on your device. No account required. No cloud sync. Your health entries are never sold, shared, or used for advertising.
• Offline-first architecture • Local encrypted storage • Export your data anytime • Delete everything with one tap
To keep improving Calmgrid, we collect anonymous usage statistics and crash reports — never the content of your health entries. You can turn this off in Settings anytime.
• Dark mode reduces strain during attacks • Quick logging when you're in pain • Skip any step — flexibility when you need it • Haptic feedback for intuitive interaction • Calm, low-contrast interface • Available in 39 languages
