## What is Datalyst?

Find out what is really behind your symptoms.

Migraines that come out of nowhere. A gut that flares after some meals but not others. Bad sleep, low energy, mood swings. Datalyst helps you log your days in seconds and then shows you which foods, habits, supplements and routines line up with your worst and best days.

TRACK ANY SYMPTOM
• Headache and migraine severity, pain, bloating, fatigue, anxiety, mood, focus
• Sleep, energy, caffeine, alcohol, food, workouts, medication timing, supplements
• Any custom variable you name, on a scale or as a number
• One quick check in a day, or as many as you need

FIND YOUR TRIGGERS
• The Lab compares what you did with how you felt and shows real correlations
• Run a simple experiment on yourself: change one thing, keep logging, see if it helped
• Results measured against your own baseline, not a population average
• Trends over weeks and months, so slow patterns stop hiding

SEE IT AT A GLANCE
• Activity heatmaps and streaks make gaps and flare ups obvious
• A dashboard that leads with what your data is telling you
• Export your log as CSV to share with your doctor or analyze yourself

BUILT FOR HONEST DATA
Logging takes seconds, because a symptom diary you skip is a diary that lies. No nagging, no gamified health, and no pretending a correlation is a diagnosis.

PRIVATE BY DEFAULT
Your symptom log is yours. Privacy policy: https://www.datalyst.one/privacy

Datalyst is a self tracking journal, not a medical device. It does not diagnose, treat, or replace professional medical advice.
