See how Nimbus Shield works
Every part of the app is designed around one question: does this help you understand your migraines?
Step 1 of 4
Log attacks and daily factors
Record attacks with pain level, symptoms, triggers and medications in seconds. Use the migraine timer to track duration, or try voice logging with on-device speech-to-text. Between attacks, log daily check-ins for water, sleep, exercise and stress.
- One-tap quick log, voice logging with on-device Whisper transcription, and preventive medication checklist.
- All data stored locally on your device. Voice audio never leaves your device.
Step 2 of 4
Review across multiple views
Your history is presented as a timeline, a colour-coded calendar and a weekly review with charts and statistics. Tap any day to view, edit or delete records.
- Calendar view shows migraine, clean and cycle days at a glance.
- No cloud sync means your history exists only where you keep it.
Step 3 of 4
Discover what affects you
Nimbus Shield analyses your records locally and surfaces findings across 19 insight categories—from triggers and sleep to weather pressure and medication efficacy. Every finding includes evidence-strength indicators. When there isn’t enough data, it says so.
- Premium insights include sleep correlation, weather sensitivity, seasonal patterns and trigger experiments.
- All analysis runs on your device—your patterns never leave.
Step 4 of 4
Export and share on your terms
Generate PDF doctor reports, monthly summaries, risk forecasts and a comprehensive year-in-review. Export your full database as JSON or CSV. Import data from other migraine apps. Nothing is shared unless you explicitly choose to share.
- PDF reports for 7, 30 or 90-day periods. JSON and CSV for full portability.
- Nothing is exported unless you explicitly choose to export it.

Important limitations
- Nimbus Shield is a tracking and informational tool, not a medical device.
- It does not diagnose, treat, cure or prevent any disease or condition.
- Findings depend entirely on the accuracy and completeness of information you record.
- Pattern identification may require weeks or months of consistent recording.
- Nimbus Shield cannot predict attacks with certainty.
- It cannot recommend or prescribe medication.
- It does not replace professional medical advice, diagnosis or treatment.
- Voice transcription uses an on-device model and accuracy depends on audio quality, accent and environment.
- Insights and correlations are observational, not clinical. Individual results vary.
