Track, Correlate & Share

Log symptoms, triggers, and treatments daily. Leo's correlation engine finds patterns across all your conditions and builds doctor-ready reports automatically. The connections it reveals — like how your sleep quality correlates with both POTS severity and migraine frequency — are patterns you'd never spot manually.

Cross-Condition Insights

POTS
Gastroparesis

POTS flares precede GI symptoms

In 78% of your gastroparesis flares, your standing HR was elevated the day before. Consider extra fluids on high-HR days.

Sleep
Migraine

Sleep under 6hrs triggers attacks

You're 3.2x more likely to have a migraine after nights with less than 6 hours of sleep.

Weather
All 3

Barometric drops affect everything

When barometric pressure drops >5 hPa, your POTS, gastroparesis, and migraine all flare within 24hrs.

Supported Conditions

Each condition pack includes curated symptoms, known triggers, episode templates, and condition-specific tracking tools

Gastroparesis

Available Now

Track gastric electrical stimulator (GES) settings, log daily symptoms using the validated GCSI scale (Gastroparesis Cardinal Symptom Index), correlate trends with device adjustments, and carry an offline ER card with your device information for emergency visits.

Gastroparesis — delayed gastric emptying — affects an estimated 5 million Americans and is commonly associated with diabetes, post-surgical complications, and idiopathic causes. Many patients rely on a gastric electrical stimulator (like the Enterra system) to manage chronic nausea and vomiting. Leo provides the most comprehensive gastroparesis management toolkit available.

Myalgic Encephalomyelitis / Chronic Fatigue Syndrome affects 1.3 million Americans with profound fatigue, post-exertional malaise (PEM), cognitive dysfunction, and unrefreshing sleep. PEM -- a disproportionate worsening of symptoms after exertion -- can be delayed by 24-72 hours, making trigger identification nearly impossible without systematic tracking. Leo's 72-hour lookback engine changes that.

New Daily Persistent Headache (NDPH)

Coming Soon

Daily severity tracking with baseline vs flare comparison, medication effectiveness scoring, trigger correlation analysis, and doctor-ready reports for a condition that's often misdiagnosed and poorly understood.

New Daily Persistent Headache is a chronic daily headache that begins abruptly — most patients can pinpoint the exact date it started — and never goes away. Often triggered by a viral illness, stressful event, or surgery, NDPH affects an estimated 0.03-0.1% of the population. With no FDA-approved treatment, tracking severity patterns, medication responses, and triggers is essential for finding what works for you.

These conditions frequently co-occur. Leo is designed to track them together, not in silos.

The Dysautonomia Cluster

POTSGastroparesisMigraine

Autonomic dysfunction affects heart rate, digestion, and cerebral blood flow. These three conditions share the same underlying nervous system dysfunction.

The EDS/POTS/MCAS Trifecta

POTSEDS (coming)MCAS (coming)

Hypermobile blood vessels, autonomic dysfunction, and mast cell overactivation. Nearly 1 in 3 patients with one has the others.

The Pain & Fatigue Overlap

FibromyalgiaIBSMigraine

Central sensitization connects widespread pain, GI dysfunction, and headache disorders. Weather and stress trigger all three simultaneously.

The Neuro-Autonomic Connection

EpilepsyMigrainePOTS

Seizures, migraines, and autonomic dysfunction frequently coexist. Shared neural excitability and autonomic pathways mean treating one often improves the others.

Lab Tracking

Condition-Specific Lab Tracking

Each condition automatically includes the lab panels that matter most — A1C and ketones for diabetes, CBC and iron for endometriosis, thyroid and inflammatory markers for fibromyalgia. Set personal target ranges, pin your most important panels, and track trends over time right from your condition hub.

  • Condition-aware defaults: each condition pack comes pre-loaded with its clinically relevant lab panels

  • Personal target ranges: set your own min/max goals (e.g., A1C 5.5-7.0%) alongside standard reference ranges

  • Pinned lab cards: your 2-3 most important panels shown as prominent cards with latest values and trend charts

  • Add any panel: track additional labs beyond the defaults — 16+ panel types available including CBC, CMP, lipid, thyroid, and more
