Nagi – Migraine Diary

Understand your triggers

Free · In‑App Purchases

Log an attack with one tap. Nagi connects your attacks to your sleep, the weather and your cycle, and keeps everything on your phone. Now in English and French. Nagi is the migraine diary you fill in 10 seconds, and everything stays on your phone. Log an attack with one tap, complete it later. Nagi connects your attacks to your sleep, the barometric pressure, your cycle and your treatments, then shows you what keeps coming back before your attacks — without ever sending anything to a server. WHAT NAGI DOES • Logs an attack in seconds: intensity, location, aura, symptoms, triggers. • Tracks your treatments and what actually brings you relief. • Connects your attacks to the weather, your sleep, your heart rate variability and your cycle. • Flags the days to watch, in the morning. • Builds a clear report for your doctor, as a PDF or a CSV. YOUR DATA STAYS WITH YOU No account, no server. Your attacks are stored in a local database, on your phone: the developer has no access to it. You can export everything or erase everything in two taps, whenever you want. FREE, WITH NO TIME LIMIT Logging your attacks will always be free. Nagi Premium opens what needs history: your personal correlations, the days to watch, how well each treatment relieves you, and the report for your doctor. Nagi is a personal logbook. It is not a medical device: it makes no diagnosis and does not replace the advice of a healthcare professional. — Nagi Premium — auto-renewing subscription • Annual, after a 7-day free trial • Quarterly, billed every 3 months The price for your country or region is shown in the app before you confirm.

  • This app hasn’t received enough ratings or reviews to display an overview.

Widgets are here, and pressure finally reads the way it should. • Four home screen widgets: "I have a migraine" starts and ends an attack without opening the app, plus Calendar, Automatic context and Nagi's vigilance. • "Your context": sleep, recovery, pressure and environment, day by day, over 7 to 90 days, each with its expected range. Touch a bar to read that day's value. • Pressure now reads as a change, not an absolute value. Station pressure depends on your altitude — Nagi tracks the drop or rise over 24 hours, and how fast it happens. • Eight measurements tracked instead of three: sleep, recovery, restless nights, pressure, air quality, noise, heat and daylight. • During an attack, a second lock screen button logs a treatment. • Home tiles show the change since yesterday, and Settings › What's new keeps the version history. Fixes: usage measurement no longer runs from development builds, an open attack can no longer be started twice from a widget or the Watch, an evening reminder opened after midnight fills in the right day, the attack timer stays readable past an hour, and the paywall no longer opens twice.
