How It Works
Passive intelligence.
Zero effort.
Your Watch collects. The weather shifts. Phoebe connects the dots and warns you before conditions align for an attack.
Step 01

Biometric Ingest

Sleep, HRV, heart rate from Apple HealthKit. Runs silently — no manual logging.

Step 02

Atmospheric Scan

Barometric pressure, humidity, temperature via WeatherKit. Your microclimate, not a city average.

Step 03

ML Prediction

XGBoost blends 27 features into a personalized Blended Risk Score. Accuracy improves over time.

Step 04

Proactive Alert

Pressure dropping and sleep was short? A contextual nudge hours before the pain window.

7-Day Forecast
See the week ahead.
Prepare, don't react.

Each morning, Phoebe shows your risk for the days ahead. A pressure front arriving Thursday? You'll know by Tuesday — with time to adjust sleep, schedule, and medication.

Bioweather Intelligence
Your weather isn't
everyone's weather.

Most people check the weather for rain. You check it for pain. Phoebe tracks barometric drops, humidity spikes, and temperature swings — pinpointed to your coordinates, updated hourly.

Voice Check-In
When it hurts too much
to look at a screen.

Hold the button and speak. “Severe right side, started an hour ago, took sumatriptan.” Phoebe logs severity, location, triggers, medication — without a single tap.

AI Health Assistant
Ask questions.
Get answers from
your data.

“What are my top triggers?” Phoebe answers from your diary only — no internet knowledge, no guessing. Your patterns, your data, your truth.

Intelligence In Action
Phoebe reaches out first.
Real scenarios. Real alerts. This is what a migraine early warning system feels like.
Pressure Front

Tomorrow looks risky.
Tonight matters.

8pm Wednesday. Pressure dropping 7 hPa by morning. Your HRV declining since lunch. Phoebe connects both signals.

Phoebe Alert
Tomorrow: 68% Risk. Barometric pressure dropping 7 hPa overnight while your HRV is below your 7-day average. Consider your preventive and prioritize sleep.
Morning Insight

Your sleep tells a story.

4.5 hours of sleep. Resting heart rate spiked to 72. Phoebe adjusts your risk before you feel a thing.

Morning Brief
Sleep was significantly below baseline. Combined with yesterday's weather shift, today carries elevated risk.
Voice Capture

Logging without looking.

Mid-attack. Lights off. You hold the button and whisper. Phoebe captures severity, triggers, medication — no screen, no forms.

Pattern Discovery

The trigger you didn't know.

After 30 days of passive data, Phoebe surfaces a compound trigger.

Phoebe AI
Your top compound trigger is poor sleep + pressure drop. This preceded 85% of your attacks this month.

Early Feedback
Tested by real sufferers.

“The barometric pressure tracking alone makes this worth downloading. I've suspected weather triggers for years but never had the data to prove it.”
Michael · Chronic Migraine

“Voice check-in is a game changer. During an attack I can barely see my phone. Being able to just talk and have it logged is exactly what I needed.”
Jacob · Episodic Migraine

“Showed my neurologist the PDF report and she was genuinely impressed. She wished more patients had data like this.”

Our Story
Built because someone
we love was suffering.

Phoebe was born from watching someone endure 15 years of chronic migraines — and realizing every app only records pain after the fact.

Named after the Greek Titaness of the Moon — because migraines, like tides, follow invisible rhythms.
