Designed for mid-migraine use: big buttons, no typing. Log episodes, pain, triggers and medication, correlate them with your sleep and steps from Health Connect, and hand your doctor a clean PDF.

Private by design
Health data is sensitive. Your diary stays on your phone; Health Connect data is read only with your permission and only on the device. Nothing is shared unless you export a PDF or opt into backup.
In your language
On first launch you pick your language. The app downloads a free on-device translation pack from Google (ML Kit) for it and translates its screens on your phone; you can change the language any time in Settings. Translations are automatic, so a phrase may read a little differently than a native speaker would put it.
FAQ
Is my health data uploaded?
No. Episodes, triggers and Health Connect data stay on your phone. The only way data leaves is a PDF you export or the optional cloud backup if you turn it on.
What does it read from Health Connect?
Sleep sessions and steps, with your permission, to correlate with episodes. You can revoke access in Health Connect at any time.
Is it medical advice?
No. It is a diary and statistics tool, not a medical device, and it does not diagnose or treat anything.
Does it support IBS?
Yes: an IBS / low-FODMAP mode (Pro) adds food logging and a reference list.
