Finally, a POTS Tracker That Actually Gets It
Guided standing test with Apple Watch HR auto-capture. Fluid and sodium tracking with POTS supplement presets. Levine/CHOP exercise protocols. Doctor-ready reports that make specialists take you seriously.
Built for the 1-3 million Americans living with Postural Orthostatic Tachycardia Syndrome. No more piecing together 5 different apps.
What is POTS?
Postural Orthostatic Tachycardia Syndrome is a form of dysautonomia -- a malfunction of the autonomic nervous system that controls involuntary functions like heart rate, blood pressure, and digestion.
The hallmark: when you stand up, your heart rate increases by 30+ bpm (adults) or 40+ bpm (adolescents) within 10 minutes, often exceeding 120 bpm. This isn't anxiety -- it's your autonomic nervous system failing to properly regulate blood flow.
The Numbers
- 1-3 million Americans affected
- 5:1 female-to-male ratio
- Average 4+ years to diagnosis
- Prevalence surged post-COVID-19
POTS patients often see 7+ doctors before getting diagnosed. Detailed standing test data and symptom logs give your doctor objective information to work with. That's what Leo provides.
POTS Subtypes
Neuropathic
Decreased sympathetic nerve function, especially in legs. Often associated with small fiber neuropathy.
Common treatment: Compression garments, midodrine
Hyperadrenergic
Elevated norepinephrine levels. Blood pressure rises on standing. Excess adrenaline symptoms.
Common treatment: Beta blockers, clonidine
Hypovolemic
Abnormally low blood volume. Both plasma and red blood cells may be reduced.
Common treatment: Fludrocortisone, IV saline, salt loading
Autoimmune
Triggered by viral illness or autoimmune response. Autoantibodies may be present.
Common treatment: IVIG, immunomodulatory therapies
Deconditioning
Physical deconditioning with reduced heart size. Often reversible with exercise.
Common treatment: Levine/CHOP reconditioning protocol
Subtypes overlap significantly. Many patients have features of multiple types.

Your Complete POTS Toolkit
Everything POTS patients need to manage their condition -- from daily tracking to doctor visits -- in one app.
Guided Standing Test
Killer FeatureThe poor man's tilt table test, reimagined. Step-by-step guided protocol with Apple Watch heart rate auto-capture at each timed interval. Audio and haptic cues tell you when to lie down, when to stand, and when to record. Automatically generates a clean HR curve chart with symptom overlay that you can share with your cardiologist or autonomic specialist.
- Apple Watch HR auto-capture
- Timed audio/haptic prompts
- Symptom logging at each interval
- HR curve chart generation
- Test history comparison over time
- PDF export for doctors
Fluid & Sodium Tracker
POTS management relies heavily on hydration (2-3L/day) and sodium intake (3,000-10,000mg/day). Quick-log with pre-loaded POTS supplement presets including Vitassium salt capsules, NormaLyte, LMNT, Liquid IV, Drip Drop, and plain salt tablets -- each with exact sodium content already calculated.
- Pre-loaded POTS supplement database
- Daily fluid goal with progress ring
- Sodium goal tracking (mg)
- Smart reminders throughout the day
- Correlate intake with symptom severity
- Weekly compliance trends
Exercise Reconditioning
Built-in Levine (Dallas) and CHOP exercise protocols -- structured reconditioning programs commonly recommended by POTS specialists. Flexible scheduling accounts for bad days. Starts with recumbent exercise (rowing, swimming, recumbent bike) and gradually progresses to upright activity over 3 months.
- Levine & CHOP protocols built in
- HR zone targets per session
- Flexible bad-day rescheduling
- No-equipment alternative exercises
- Monthly progression tracking
- Exercise tolerance logging
HR Position Overlay
Throughout the day, see your heart rate data tagged by body position -- lying, sitting, and standing -- pulled automatically from Apple Watch and HealthKit. Instantly visualize how much your heart rate spikes when you stand versus when you're resting, with daily trend charts and weekly averages.
- Automatic position detection via HealthKit
- Lying vs sitting vs standing HR bands
- Daily and weekly trend views
- Resting HR baseline tracking
- Tachycardia episode detection
- Share charts with care team
Brain Fog Tracker
POTS brain fog -- described as feeling "forgetful, cloudy, and unable to focus" -- affects the majority of patients. Track cognitive symptoms with a simplified scale based on the Fatigue and Altered Cognition Scale (FACs). Log brain fog severity alongside triggers (fatigue, dehydration, prolonged standing, poor sleep) to identify your personal patterns.
- Simplified FACs-based cognitive scale
- Quick daily brain fog rating
- Trigger correlation (sleep, hydration, standing)
- Cognitive symptom trend charts
- Compare foggy days vs clear days
- Share patterns with neurologist
Dysautonomia ER Card
An offline emergency card that explains POTS to ER staff who may not be familiar with the condition. Includes your POTS subtype, current medications and dosages, resting vs standing heart rate ranges, what helps (IV saline, lying flat) and what to avoid (forcing the patient to stand), allergies, and emergency contacts.
- Works offline -- no internet needed
- POTS subtype & diagnostic details
- Current medications & dosages
- Do's and don'ts for ER staff
- Emergency contact info
- Share via AirDrop or screenshot
POTS Report Card
Generate doctor-ready PDF reports organized the way autonomic specialists actually want to see data: standing test results over time, medication response patterns, fluid/salt compliance percentages, exercise program progress, and symptom frequency trends. Stop being dismissed -- let your data speak.
- Standing test trend charts
- Medication response analysis
- Fluid & salt compliance stats
- Exercise protocol progress
- Symptom frequency heatmap
- Export as PDF or share directly
Compression Garment Logger
Track which compression garments you wear, for how long, and correlate usage with symptom severity. Lower body compression (legs + abdomen at 20-30 mmHg) is most effective for reducing blood pooling. See whether compression days correlate with fewer symptoms.
- Log garment type & compression level
- Track hours worn per day
- Symptom severity correlation
- Compare compression vs no-compression days
- Garment reminder notifications

POTS Rarely Travels Alone
Leo's multi-condition system lets you track POTS alongside common comorbidities. Because managing the EDS/POTS/MCAS trifecta shouldn't require 5 separate apps.
Ehlers-Danlos Syndrome
In LeoHypermobile blood vessels contribute to blood pooling. Part of the EDS/POTS/MCAS trifecta.
Mast Cell Activation
Histamine release worsens tachycardia. 31% of POTS+EDS patients have MCAS.
Gastroparesis
In LeoDelayed gastric emptying. GI symptoms common in POTS. Leo has full GP tracking.
Migraine
In LeoVery common comorbidity. Shared autonomic dysregulation pathways.
Fibromyalgia
In LeoWidespread pain, fatigue, and cognitive dysfunction overlap significantly.
ME/CFS
Overlapping fatigue, post-exertional malaise, and orthostatic intolerance.
IBS
In LeoGI motility dysfunction. Autonomic nervous system affects gut function.
Long COVID
POTS is one of the most common post-COVID dysautonomia presentations.
