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.

Condition-native tracking for POTS and dysautonomia — and the doctor report your cardiologist actually wants
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.
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.
02
See the pattern
Stable surfaces what moves your symptoms — sodium, fluids, your standing heart rate — and warns you when a flare is trending.
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.
