iPhone
Track every headache and migraine in seconds, then understand your own patterns. Your full history stays private on your device and is always yours to keep and back up.
Understand your headaches and migraines without giving up your privacy.
Cephalo is a headache and migraine diary that keeps every entry on your iPhone, so you can log an attack in seconds and see what your own patterns are telling you.
Track the moments that matter: when a headache starts and ends, how intense it feels, symptoms like aura, nausea, and sensitivity to light or sound, the medication you took, and the possible triggers around you.
YOUR DATA IS ALWAYS YOURS - FOR FREE
Cephalo's free tier never caps your history. Record as many entries as you like, keep your full timeline, and back up everything to a JSON file you control, anytime. Your diary is yours to own.
CEPHALO PLUS - SEE THE PATTERNS
Upgrade to Plus when you want help making sense of it all:
- Doctor-ready PDF report that summarizes your history in clear counts to bring to your appointment
- Pattern analysis that highlights what often appears before a difficult day
- Highlights of the conditions that have shown up before your harder days in the past
- Pattern and insight summaries across weeks and months
- Weather and barometric-pressure correlation views
- MIDAS disability trends over time
- CSV export for your own spreadsheets
Plus turns your own history into understanding. It helps you spot patterns and prepare for your doctor - it never diagnoses or treats.
