Stable — POTS Tracker

Condition-native tracking for POTS and dysautonomia — and the doctor report your cardiologist actually wants.

Stable is the daily tracker built specifically for POTS and dysautonomia — not another generic symptom diary. Log the symptoms that define the condition, run the lying-to-standing orthostatic heart-rate test, hit your salt and fluid targets, and turn it all into a dense, factual PDF designed for a cardiology appointment. Everything stays on your device — no account, no cloud.

What you get

Stable — POTS Tracker was built for exactly this.

The core features that make Stable — POTS Tracker different from the generic alternatives.

Condition-native logging

fatigue, brain fog, palpitations, dizziness, pre-syncope, headache, nausea, and tremor on a 0–10 scale — plus your own custom symptoms — in two taps.

Orthostatic heart-rate test

the lying-to-standing test built in, with Apple Health (Apple Watch) capture or manual entry, computing your delta and flagging a rise of 30 bpm or more.

Salt & fluid targets

set the sodium (mg) and fluid (ml) targets your care team gave you and count toward them with one-tap quick-adds.

Doctor Report (Pro)

a clinician-grade PDF — orthostatic vitals table with flags, daily symptom-burden chart, per-symptom frequency, sodium/fluid adherence, flare and pre-syncope episode logs — generated entirely on-device.

Insights & early warning (Pro)

correlations between symptoms and sodium, fluid, and HR delta; a flare timeline; and a 3-day trend signal.

The Levine Protocol (Pro)

track the 8-month recumbent-to-upright reconditioning program phase by phase, with a session log.

Private by design

no account, no cloud, no servers. Your health data never leaves your device.

A note from the studio

Every symptom tracker I tried treated POTS like a bad mood. None of them knew what an orthostatic delta was, or could hand my cardiologist a single page she'd actually read. Stable is that page — and the daily logging that earns it.

How it works

Three steps. No account. No tracking.

  1. 01

    Log in seconds

    Tap a symptom, set severity, add salt and fluids as you go. Run a standing test when you feel off. It all stays on your phone.

  2. 02

    See the pattern

    Stable surfaces what moves your symptoms — sodium, fluids, your standing heart rate — and warns you when a flare is trending.

  3. 03

    Bring proof to your doctor

    Generate the Doctor Report PDF and share it before your appointment — orthostatic vitals, flares, and adherence, on one clean clinical page.
